What Does a Technical SEO Consultant Do? Tasks, Audits and Fixes
A technical SEO consultant diagnoses website infrastructure problems that make it harder for search engines to discover, crawl, render, index, and understand important pages. They investigate issues such as incorrect indexing directives, broken redirects, duplicate URLs, JavaScript rendering problems, weak site architecture, and performance limitations, then recommend or implement fixes based on their impact.
Technical SEO is important because valuable content cannot reach its full search potential if search engines cannot access or process it properly. However, fixing technical issues does not automatically guarantee higher rankings. Search visibility also depends on content relevance, quality, competition, and other factors.
For businesses in competitive markets such as New York, a technical SEO consultant can help identify the underlying website problems that should be addressed before investing more heavily in content or other SEO activities.
If your website needs a broader strategy covering technical SEO, local search, content optimisation, and organic visibility, explore my SEO services in New York to understand how these areas fit together.
What is a technical SEO consultant?
A technical SEO consultant is an SEO specialist who evaluates the technical systems and website structure that affect how search engines access and interpret a website.
Their work often involves analysing the relationship between URLs, crawlability, indexability, redirects, canonical signals, site architecture, JavaScript, structured data, and page experience.
Unlike a consultant whose work focuses primarily on keyword research or content writing, a technical SEO consultant investigates issues beneath the visible content of a page. They may work directly with developers, site administrators, marketing teams, and other SEO specialists to resolve those issues.
The exact scope depends on the website. A small service-business website might need corrections to indexing settings and internal links. A large eCommerce website may require more extensive investigation into faceted navigation, duplicate URLs, product indexing, and site migrations.
A good consultant does more than produce a list of technical warnings. They explain which issues matter, why they matter, how they should be resolved, and how to verify the results.
What does a technical SEO consultant actually do?
The work generally follows a process of investigation, prioritisation, implementation, and validation.
1. Audit website crawling and accessibility
Search engines need to discover and access the pages that a business wants to appear in search results.
A technical SEO consultant examines whether important pages are accessible to search-engine crawlers and whether the website’s navigation and internal links make those pages easy to discover.
Typical checks include:
- Broken internal links and inaccessible pages.
- Important pages with few or no internal links.
- Robots.txt rules that unintentionally block useful resources or pages.
- Server responses and HTTP status codes.
- Redirects, redirect chains, and redirect loops.
- XML sitemap accuracy and consistency.
- Website sections that are difficult to discover through navigation.
For example, an important service page may exist and look normal to visitors but have no meaningful internal links pointing to it. A consultant would investigate how the page is discovered, whether it can be crawled, and whether its position in the website structure makes sense.
Google’s technical requirements for Search explain that Google needs access to a working page with indexable content for it to be eligible for indexing. Meeting those requirements does not guarantee that Google will index the page. <Cite refs={[“turn616574view0”]}/>
2. Diagnose indexing and canonicalisation problems
Crawling and indexing are related, but they are not the same.
Crawling means a search engine accesses a URL. Indexing involves processing the page and deciding whether to include it in the search index.
A consultant investigates why important pages may be excluded, why Google may select a different URL than intended, or why duplicate versions of a page exist.
Common checks include:
- Accidental
noindexdirectives. - Conflicting canonical tags.
- Duplicate or near-duplicate URLs.
- HTTP and HTTPS or trailing-slash URL inconsistencies.
- Redirects to irrelevant or incorrect destinations.
- Sitemap entries pointing to redirecting or non-canonical URLs.
- Important pages returning errors instead of valid content.
Consider an eCommerce website with several URLs displaying substantially the same product information. The consultant would examine which versions should remain accessible, whether canonical signals are consistent, and whether unnecessary URL variations are creating technical complexity.
A canonical tag is a signal that helps Google identify the preferred URL, but Google can select a different canonical when its systems determine another version is more appropriate. <Cite refs={[“turn149052search1″,”turn149052search9”]}/>
The objective is not to force every URL into Google’s index. It is to make sure important, useful pages are accessible and represented correctly.
3. Investigate JavaScript rendering issues
JavaScript can power interactive navigation, filters, product experiences, and other website features. However, problems may arise when essential content or links are not rendered or exposed in a way that search engines can process correctly.
A technical SEO consultant may investigate whether:
- Important page content is present in the rendered HTML.
- Internal links use crawlable destinations.
- JavaScript errors prevent essential content from appearing.
- Navigation depends on interactions that crawlers cannot use as expected.
- Metadata or canonical tags are changed inconsistently after rendering.
- Error pages return appropriate status codes.
For example, a service page may appear complete in a browser, but an implementation problem could prevent its main content from being available to search engines in the expected way. The consultant should reproduce the issue, inspect the rendered page, and work with the development team on a suitable solution.
Google can process JavaScript, but its documentation explains that JavaScript-powered sites have additional crawling, rendering, and indexing considerations. <Cite refs={[“turn616574view1″,”turn149052search2”]}/>
The correct response is not to assume all JavaScript is harmful. It is to identify whether the implementation creates a real discoverability or indexing problem.
4. Improve website architecture and internal linking
Website architecture determines how pages are organised and how people and search engines navigate between them.
A technical SEO consultant reviews whether important pages have clear paths from relevant sections of the website and whether the URL structure reflects a logical organisation.
Typical tasks include:
- Identifying orphan pages.
- Reviewing navigation and directory structure.
- Improving contextual internal links.
- Finding unnecessary levels of navigation depth.
- Detecting broken links and redirecting links.
- Consolidating redundant or overlapping URLs when appropriate.
- Ensuring important service, product, and category pages are discoverable.
For example, a business might publish several helpful articles about a service but rarely link them to the service page that generates enquiries. A consultant can identify relevant connections and recommend contextual links that help visitors discover the next useful resource.
This is also where technical SEO connects with content strategy. Internal linking should reflect meaningful relationships between pages instead of inserting exact-match keywords into every link.
Google recommends making important content easy to find through internal links, including when preparing a site for its generative AI search experiences. <Cite refs={[“turn153104search0″,”turn153104search1”]}/>
5. Evaluate page speed and Core Web Vitals
A technical SEO consultant investigates performance problems that affect how quickly and reliably pages load and respond to user interactions.
The review may include Core Web Vitals, mobile performance, large page resources, layout shifts, slow server responses, and unnecessary scripts.
Common issues include oversized images, excessive third-party scripts, render-blocking resources, poorly configured caching, and inefficient page templates.
However, the consultant should diagnose the cause instead of treating a single speed score as the entire SEO strategy.
For example, an eCommerce website with slow product pages may need a combination of image optimisation, script reduction, template changes, and developer-level performance work. A simple image-compression plugin may not address the underlying problem if the main bottleneck is elsewhere.
Google uses Core Web Vitals within its ranking systems, but its guidance explains that good scores do not guarantee top rankings and should not be pursued in isolation from the overall user experience. <Cite refs={[“turn616574search0″,”turn616574search3”]}/>
The practical objective is to improve the experience for visitors while resolving technical issues that affect the website.
6. Review structured data and technical eligibility
Structured data helps describe information about a page in a standardised format that supported search features can understand.
A consultant may review whether relevant schema markup is implemented accurately, whether it matches the visible page content, and whether the implementation produces errors or misleading information.
Depending on the website, relevant markup may include Organisation, Product, Breadcrumb, Article, or other appropriate types.
For example, an eCommerce website may need a review of Product markup, while an informational article may benefit from suitable Article markup.
Structured data should describe the actual page, not information invented to obtain a search feature. Valid markup may make a page eligible for particular rich results, but Google does not guarantee that those features will appear. <Cite refs={[“turn616574search2″,”turn616574search4”]}/>
A consultant should recommend schema only when it fits the content and supported search features. Adding more markup is not automatically better.
7. Support website migrations and major technical changes
Website redesigns, domain changes, platform migrations, and structural changes can introduce technical problems if URL changes and redirects are not handled carefully.
A technical SEO consultant may help plan the migration before launch, prepare URL mapping, check redirects, review canonical tags, update internal links, and monitor the site after deployment.
Typical responsibilities include:
- Crawling the existing website and recording important URLs.
- Mapping old URLs to their relevant new destinations.
- Identifying pages that should remain, be consolidated, or be retired.
- Checking redirects and HTTP responses.
- Reviewing robots directives, canonical tags, and sitemaps.
- Verifying important pages after launch.
- Monitoring indexing and organic performance for unexpected changes.
For example, if a website changes its service-page URLs but does not redirect the old URLs properly, visitors and search engines may encounter broken destinations. A migration plan helps the team identify and reduce these risks before they affect important pages.
A consultant cannot guarantee that a migration will preserve every ranking. The goal is to prevent avoidable errors, maintain clear signals, and detect problems quickly.
8. Coordinate with developers to implement fixes
A technical audit only creates business value when important issues are addressed.
Some changes can be made through a CMS or SEO plugin. Others require developer access to templates, server configuration, routing, rendering logic, or other technical systems.
The consultant should be clear about which work they can implement and which work requires another specialist.
Useful implementation documentation identifies:
- The issue and affected URLs.
- Evidence showing the problem.
- Why it matters.
- The proposed fix.
- The person or team responsible.
- Any dependencies or risks.
- How success will be validated.
For example, a recommendation to fix canonical tags should explain which URL variations are affected, the intended canonical destination, why the existing configuration is problematic, and how to test the change after deployment.
This approach makes technical recommendations easier for developers and business owners to understand, approve, and implement.
What should a technical SEO audit deliver?
A professional audit should provide more than an automated crawl report or a list of errors from an SEO tool.
It should turn the findings into a practical action plan.
| Deliverable | What it should contain |
|---|---|
| Technical issue log | Identified problems, evidence, affected URLs, and relevant findings |
| Priority assessment | Which issues deserve attention first and why |
| Recommended fixes | Clear instructions suitable for the person implementing the changes |
| Implementation roadmap | Responsibilities, dependencies, and suggested order of work |
| Validation plan | How the team will confirm that each important fix works |
| Monitoring approach | Relevant Search Console, crawl, performance, and business indicators |
A useful audit also distinguishes widespread template problems from isolated URL issues. Fixing a shared template may address hundreds of affected pages, while a one-off redirect may require only a small correction.
The goal is to focus effort on the findings most relevant to the website’s health and business objectives.
For a broader review framework, see my SEO audit checklist for businesses in New York.
How does a technical SEO consultant prioritise problems?
Not every warning found by an SEO crawler deserves immediate attention.
A consultant should consider the severity of the issue, the importance of affected pages, how widespread the problem is, the confidence in the diagnosis, and the cost or risk of fixing it.
Consider this illustrative prioritisation framework:
| Priority | Example issue | Typical response |
|---|---|---|
| High | Important service pages are accidentally blocked or set to noindex | Investigate promptly and correct the directive if it is genuinely unintended |
| High | A migration redirects valuable pages to irrelevant destinations | Review URL mapping and correct the redirect strategy |
| Medium | Important pages have weak internal links | Improve relevant navigation and contextual links |
| Medium | A template has avoidable rendering or performance problems | Diagnose the cause and plan a safe implementation |
| Lower, depending on context | Minor technical warnings affecting few or unimportant URLs | Assess whether the issue creates meaningful impact before spending resources |
These categories are examples, not universal rules. An issue’s priority depends on the affected URLs, the website’s configuration, and the evidence available.
The important principle is to avoid treating every warning as equally urgent. A consultant should explain which findings deserve immediate work and which can wait.
When should you hire a technical SEO consultant?
You may benefit from specialist technical SEO support if your website shows symptoms that cannot be explained by content quality or keyword targeting alone.
Common situations include:
- Important pages are missing from Google Search.
- Organic traffic drops following a redesign or migration.
- Google indexes unexpected URLs or selects the wrong canonical pages.
- Search engines struggle to access important JavaScript-rendered content.
- An eCommerce website has extensive duplicate URLs or indexing problems.
- A site has technical issues that repeatedly return after superficial fixes.
- Your development team needs clear technical SEO specifications.
- You are planning a major platform change and need SEO risks assessed before launch.
A technical SEO consultant may be less urgent if your website has no material technical problems and the main challenge is a lack of useful content, weak product-market fit, or limited business demand. In those cases, other forms of SEO or marketing work may be more appropriate.
The right decision begins with diagnosing the problem instead of automatically purchasing a technical audit.
What is the difference between a technical SEO consultant and a web developer?
A web developer builds, maintains, and improves website functionality. A technical SEO consultant focuses on how the website’s technical implementation affects search discovery, rendering, indexing, and other SEO requirements.
These responsibilities often overlap.
| Technical SEO consultant | Web developer |
|---|---|
| Diagnoses search-related technical issues | Implements changes in code, templates, or systems |
| Explains affected URLs and SEO implications | Evaluates implementation requirements and technical risks |
| Recommends crawlability and indexability improvements | Updates routing, rendering, server responses, or other technical components |
| Defines validation criteria for SEO fixes | Tests the implementation and resolves development issues |
Some professionals perform both roles, but you should confirm the scope before hiring.
A good working relationship allows the consultant to specify the search-related problem and the developer to implement a maintainable solution.
Is technical SEO different from on-page SEO?
Yes. The two disciplines are related, but they focus on different aspects of a website.
Technical SEO addresses how search engines access, render, and process pages. On-page SEO focuses more heavily on visible content and page-level signals, including titles, headings, search intent, and the usefulness of the information.
For example, a service page may have excellent content but an accidental noindex directive. That is a technical issue. Another page may be accessible and indexed but fail to explain its service clearly or address the customer’s needs. That is more directly an on-page content problem.
Some issues cross both areas. A consultant may need to assess page structure, internal linking, and canonical signals together to understand the full situation.
For sustainable search performance, neither technical health nor useful content should be treated as a complete replacement for the other.
Does technical SEO help with Google AI Overviews, AEO, and GEO?
Technical SEO can help ensure that important content is accessible to search engines and eligible for discovery. That is relevant to both conventional Google Search and its AI-powered search experiences.
Google’s guidance for AI Overviews and AI Mode states that the same foundational SEO requirements remain relevant. To be eligible for supporting links in these experiences, a page must be indexed and eligible to appear in Google Search with a snippet; inclusion is not guaranteed. <Cite refs={[“turn153104search0″,”turn153104search3”]}/>
Technical work relevant to this foundation may include:
- Ensuring important pages can be crawled.
- Confirming that valuable content is available in an accessible textual form.
- Checking JavaScript rendering where applicable.
- Making important pages easy to find through internal links.
- Reviewing whether structured data accurately matches visible content.
- Maintaining a useful, stable experience across devices.
Answer Engine Optimisation (AEO) and Generative Engine Optimisation (GEO) describe approaches to improving how content is understood and discovered in answer-oriented and generative search experiences. They do not remove the need for technically accessible pages or useful information.
There is no special technical SEO setting, schema type, or AI text file that guarantees a citation in Google AI Overviews, ChatGPT, or another AI system. Google’s current guide to generative AI features in Search recommends established SEO practices, distinctive content, and a clear technical structure. <Cite refs={[“turn153104search0″,”turn153104search8”]}/>
A capable consultant should focus on specific problems and practical improvements rather than sell guaranteed AI visibility.
How do you evaluate a technical SEO consultant before hiring?
Before hiring a specialist, ask questions that reveal how they investigate problems and turn findings into usable improvements.
1. How will you identify the main problems on my website?
Look for a process that considers the business, important URLs, Search Console data, crawling, indexing, and relevant technical evidence.
2. Will you prioritise issues or simply provide a crawl report?
A useful audit should explain why issues matter and which findings deserve attention first.
3. Will you implement the fixes?
Clarify which tasks are included, which require a developer, and what implementation support costs extra.
4. How will you validate the changes?
Ask how the consultant will confirm that the fix works using appropriate crawling, URL inspection, testing, and monitoring.
5. Have you handled websites with similar technical complexity?
Experience with a website of similar size, platform, or migration complexity can be more relevant than a generic list of services.
6. How will you measure results?
The consultant should distinguish successful implementation from longer-term changes in indexing, search visibility, and organic performance. No one can responsibly guarantee a specific ranking.
Google also recommends evaluating an SEO provider’s previous work, communication, proposed methods, and approach to measuring success. See its guide to hiring an SEO. <Cite refs={[“turn149052search6″,”turn149052search5”]}/>

Frequently asked questions
What does a technical SEO consultant do?
A technical SEO consultant investigates and resolves website infrastructure issues that affect how search engines discover, crawl, render, index, and understand important pages. The work may cover redirects, indexing directives, canonicalisation, JavaScript rendering, internal links, site architecture, structured data, and performance.
What should a technical SEO audit include?
A suitable audit may include crawling, indexability, redirects, canonical signals, sitemap and robots.txt review, JavaScript rendering, internal linking, structured data, and page experience. The scope should reflect the website and produce prioritised recommendations with clear validation steps.
Can a technical SEO consultant guarantee higher rankings?
No. A consultant can identify and address technical obstacles, but rankings depend on additional factors, including relevance, content quality, competition, and Google’s ranking systems. Technical corrections do not guarantee a specific position.
Is technical SEO important for a new website?
Yes. Establishing sensible URL structures, internal navigation, indexability controls, and accessible content can prevent avoidable problems. However, a new website still needs useful content and a clear purpose; technical correctness alone does not guarantee rankings.
How does technical SEO affect AI search?
Technical SEO helps make content accessible and eligible for discovery. Google’s AI search experiences use the same foundational Search requirements, but meeting them does not guarantee inclusion in AI-generated answers or citations.
Does every website need a technical SEO audit?
Not every website needs an extensive audit at the same frequency. The appropriate level of investigation depends on the website’s complexity, current problems, recent changes, search performance, and business priorities. Significant drops, migrations, indexing problems, and complex sites often justify deeper technical review.
Final thoughts: Technical SEO should solve real website problems
A technical SEO consultant should do more than identify warnings in an automated tool. They should determine whether the issues are real, explain which pages are affected, prioritise fixes, and help your team verify the changes.
The objective is to create a website that search engines can access and process effectively while providing visitors with a useful experience. That technical foundation supports SEO work, but it does not replace relevant content, appropriate strategy, or ongoing measurement.
If your website has persistent indexing problems, technical errors, migration risks, or structural issues that are difficult to diagnose, a focused technical SEO review may be a useful starting point.
For businesses targeting New York, my SEO services in New York page explains how technical optimisation fits into a broader SEO strategy.
Choose the work that addresses your website’s actual needs, and judge its value by the quality of the diagnosis, the implementation, and the evidence gathered after the changes.
