What technical SEO actually covers
Technical SEO is everything that affects how search engines access and understand your pages, apart from the content itself. A well-written page still fails if it is blocked by robots.txt, buried deep in the site, slow on mobile or duplicated across several URLs. Fixing these problems removes the ceiling on every other SEO effort.
Crawlability
Making sure bots can reach important pages through clean internal links, sensible robots.txt rules and no crawl traps.
Indexing
Checking what Google and Bing have indexed, removing thin or duplicate pages and fixing “Discovered, not indexed” problems.
XML sitemaps
Clean sitemaps that list only canonical, indexable URLs and are submitted in Search Console and Bing Webmaster Tools.
Canonicals and redirects
One preferred URL per page, correct 301 redirects and no chains or loops that waste crawl budget.
Site architecture
A logical hierarchy and internal linking so authority flows to key pages and visitors never get lost.
Schema markup
Structured data such as Organization, Article, FAQ and Product so search engines understand your content.
Mobile and security
Mobile-friendly layouts, HTTPS everywhere and no mixed-content warnings.
Errors and broken links
Finding 404s, soft 404s and server errors before they cost you visibility.
Core Web Vitals and page speed
Google uses real-user data to judge page experience. The three Core Web Vitals are Largest Contentful Paint (how fast the main content appears), Interaction to Next Paint (how quickly the page responds) and Cumulative Layout Shift (how stable the layout is). I test with PageSpeed Insights, GTmetrix and Search Console, then fix the causes instead of chasing scores.
- Compress and correctly size images, use modern formats and lazy-load media below the fold
- Remove render-blocking CSS and JavaScript and defer what is not needed immediately
- Set width and height on images and embeds to prevent layout shifts
- Improve server response with better hosting, caching and a CDN where it helps
- Cut unused third-party scripts that slow down interaction
My technical SEO process
Crawl and collect
I crawl the site with Screaming Frog and combine the data with Search Console, Bing Webmaster Tools and GA4.
Diagnose
Every issue is grouped by type and judged by impact, so one important fix is never buried under 200 minor warnings.
Prioritize
You get a roadmap sorted by impact and effort, with the reason behind each recommendation.
Implement
Where I have access I make the fixes myself; otherwise I give your developer exact, copy-ready instructions.
Verify and monitor
I re-crawl, request re-indexing for fixed pages and track results over the following weeks.
Problems I commonly find
- Important pages accidentally set to noindex or blocked in robots.txt
- Duplicate content from www and non-www, HTTP and HTTPS, or URL parameters
- Sitemaps that include redirected, broken or non-canonical URLs
- Orphan pages with no internal links pointing to them
- Missing or invalid schema markup
- Slow mobile pages caused by oversized images and heavy scripts
- Site migrations that dropped redirects and lost rankings
