Quick answer
What does a technical SEO expert do?
When you hire a technical SEO expert, you get a specialist who makes sure search engines can crawl, render and index your website. They fix indexing errors, duplicate pages, redirects, sitemaps, robots.txt, site structure, schema markup, mobile issues and page speed. This builds the base that content and links need to rank.
Key takeaways
- Technical SEO makes sure Google can find, read and index your pages.
- Common issues are indexing errors, duplicates, broken redirects and slow pages.
- Google Search Console is the main free tool to spot problems.
- Site migrations and redesigns need technical SEO planning to avoid traffic loss.
- Schema markup helps search engines and AI tools understand your content.
- Hire project-based for an audit and fixes, monthly for large or changing sites.
What does a technical SEO expert do?
A technical SEO expert checks and fixes the parts of your website that affect how search engines crawl, render and index it. They focus on structure and code, not on writing content.
When you hire a technical SEO expert, you get someone who reads your site the way a search engine does. They find pages Google cannot reach, pages it should not see, and pages that compete with each other.
Main tasks a technical SEO specialist handles
- Full crawl of the site to find errors, redirects and orphan pages
- Fixing pages marked 'Crawled - currently not indexed' or 'Discovered - currently not indexed' where possible
- Canonical tags and duplicate content control
- XML sitemap and robots.txt setup
- Redirect chains, loops and broken links
- Site structure, URL format and internal linking
- Schema markup for organisation, services, products, FAQs and articles
- Mobile usability and Core Web Vitals
- hreflang for sites in more than one language or country
- JavaScript rendering checks for React and similar sites
Technical SEO vs on-page SEO vs off-page SEO
Technical SEO fixes the site's base, on-page SEO improves each page's content and tags, and off-page SEO builds trust through links and mentions. All three work together.
| Type | Focus | Examples |
|---|---|---|
| Technical SEO | How the site works | Indexing, speed, sitemaps, redirects, schema |
| On-page SEO | What each page says | Titles, headings, content, images, internal links |
| Off-page SEO | What others say about you | Backlinks, reviews, brand mentions, local listings |
A technical SEO specialist often works with a general SEO expert. If you need full SEO, see our SEO experts. For local rankings in Maps, see our Local SEO experts.
Why are my pages not indexed by Google?
Pages are often not indexed because Google sees them as low value, duplicate, blocked, poorly linked or too slow to crawl. Search Console's Pages report shows the reason for each group.
| Search Console status | Common cause | Typical fix |
|---|---|---|
| Excluded by 'noindex' tag | Noindex left on by theme or plugin | Remove tag on pages that should rank |
| Blocked by robots.txt | Wrong rule in robots.txt | Correct the file |
| Duplicate without user-selected canonical | Same content on many URLs | Set canonicals, merge or redirect |
| Crawled - currently not indexed | Thin or similar content | Improve content, internal links |
| Discovered - currently not indexed | Low crawl priority or weak links | Better internal links and sitemap |
| Page with redirect | URL now redirects | Update internal links and sitemap |
| Not found (404) | Deleted or moved page | Redirect or fix links |
How does a technical SEO audit work?
A technical SEO audit crawls your site, checks Search Console data and lists issues by priority. You get a clear fix list, not just a long tool export.
- 1
Access and goals
We get read access to Search Console, Analytics and the site, and agree on key pages and markets.
- 2
Crawl the site
We crawl every URL to find status codes, redirects, canonicals, titles, depth and links.
- 3
Check index coverage
We compare what is crawled, what is in the sitemap and what Google has indexed.
- 4
Review speed and mobile
We check Core Web Vitals and mobile layout on key templates.
- 5
Check structured data
We test schema on key pages and plan missing types.
- 6
Prioritise fixes
We rank issues by impact and effort and share a simple fix plan.
- 7
Fix and verify
We make or guide the fixes, then request re-crawl and track results.
Many fixes need code changes. Our web development experts can apply them if your own developer is busy.

Technical SEO for site migrations and redesigns
A site migration or redesign is the riskiest moment for SEO. Without a redirect plan, you can lose rankings that took years to build.
Migration checklist
- Full list of old URLs with traffic and links
- One-to-one redirect map from old to new URLs
- Titles, headings and content kept or improved on key pages
- Staging site blocked from Google during build
- Noindex and robots rules removed at launch
- New XML sitemap submitted in Search Console
- Internal links updated to new URLs
- Daily checks for 404 errors in the first weeks after launch
Signs your site needs a technical SEO check
- Traffic dropped suddenly after an update, redesign or plugin change
- New pages take weeks to appear in Google
- Search Console shows a rising number of excluded or error pages
- Wrong pages rank for your main keywords
- Old URLs still show in search results after a move
Domain changes, moving from HTTP to HTTPS, platform changes (for example WordPress to Shopify) and URL structure changes all count as migrations. Plan them with a technical SEO expert before work starts, not after traffic drops.
Schema markup and AI search: why structure matters
Schema markup tells search engines and AI tools what your content is about in a clear, machine-readable way. It can help pages qualify for rich results and be understood better.
- Organization and LocalBusiness schema for your brand details
- Service and Product schema for what you sell
- Article and BreadcrumbList schema for blog and site structure
- FAQPage and HowTo where content fits the format
Clean structure, clear headings and correct schema also help AI search tools read your pages. To grow your presence in AI answers, see our AI SEO experts. Google's own guidance is at Google Search Central.

Frequently Asked Questions
What is the difference between technical SEO and regular SEO?
Regular SEO usually covers content, keywords, on-page tags and links. Technical SEO focuses on the site's base: crawling, indexing, redirects, sitemaps, speed, schema and structure. Technical SEO makes sure search engines can read your site, so content and links can do their job.
How much does a technical SEO audit cost in India?
Cost depends on the number of URLs, the platform, how many issues exist and whether we also apply fixes. A small business site needs less time than a large store with thousands of products. You get a clear written quote after a free call and a quick look at your site.
How long does it take to see results from technical SEO fixes?
Some fixes, like removing a wrong noindex tag, can show results within days after Google re-crawls. Others, like improving site structure or content quality, may take several weeks to a few months. Search Console helps track progress page by page.
Why does Google say crawled but not indexed?
This means Google visited the page but chose not to add it to the index for now. Common reasons are thin or similar content, weak internal links or low overall site quality. Improving the page, linking to it from strong pages and removing near-duplicates often helps.
Do I need a technical SEO expert for a website redesign?
Yes, if your current site has traffic you want to keep. A technical SEO expert plans redirects, keeps important content and checks the launch. Without this, a redesign can cause a sharp drop in rankings and leads.
Can a technical SEO expert fix my Shopify or WordPress site?
Yes. Both platforms have common technical issues, such as duplicate collection URLs on Shopify or tag and archive bloat on WordPress. Our experts know these platforms and can fix most issues with settings, theme edits or small code changes.
Does schema markup improve rankings?
Schema markup is not a direct ranking boost, but it helps search engines understand your content and can make pages eligible for rich results. It also helps AI tools read your business details more clearly, which supports visibility in AI answers.
Can I hire a technical SEO expert for one problem only?
Yes. Hourly hiring works well for a single problem such as a sudden indexing drop, a redirect issue or a sitemap error. If the issue points to bigger problems, the expert will suggest a full audit.
