Google From Ranking Your Site

Fix What Moves Rankings
Why Rankings Stall
Your Content Can’t Rank if Google Can’t Properly Crawl It
You can publish great content every week and still see flat rankings. The culprit is usually technical — pages that aren’t being indexed, signals that contradict each other, or a site that loads too slowly for Google to spend time crawling deeply.
🕷️ Crawlability Problems
- Pages blocked in robots.txt by accident
- Orphan pages with no internal links pointing to them
- Crawl budget wasted on low-value URLs
- Duplicate content confusing which page should rank
⚡ Speed & Stability Problems
- LCP above 2.5s — a direct ranking signal failure
- Layout shift (CLS) that Google flags as poor experience
- Render-blocking scripts slowing every page load
- Uncompressed images adding seconds to mobile load
📋 Indexing & Signal Problems
- Canonical tags pointing to the wrong URL
- Missing or malformed XML sitemaps
- Hreflang errors on multilingual sites
- Pages indexed that should be excluded — and vice versa
What We Fix
Our Technical SEO Services
We cover every technical layer — from the way Google crawls your site to how AI search engines interpret your content structure.
Full Technical SEO Audit
The starting point for every technical engagement. We crawl your entire site and produce a prioritized report — not an automated list of 400 issues with no clear next step.
- Complete site crawl using professional tools
- Indexation status check for every key page
- Crawlability & crawl budget analysis
- Duplicate content & canonical review
- Internal link structure mapping
- Prioritized issue list — high, medium, low impact
- Actionable fix recommendations per issue
Core Web Vitals Optimization
Google uses LCP, CLS and INP as ranking signals. If your site fails these, you’re at a disadvantage on every search result page — regardless of how good your content is.
- LCP diagnosis & fix — images, fonts, server response
- CLS elimination — unstable layouts, ad shifts, late-loading elements
- INP improvements — JavaScript execution, event handling
- Page speed analysis (mobile & desktop)
- Render-blocking script identification & removal
- Image compression & lazy loading implementation
- Pre-launch CWV checks on redesigns
Crawl & Indexation Management
Google has a limited budget to crawl your site. We make sure it spends that budget on the pages that matter — and that every important page is actually being indexed.
- robots.txt review & correction
- XML sitemap creation & submission
- Crawl budget analysis & optimisation
- URL parameter handling configuration
- Orphan page identification & internal linking fixes
- Google Search Console indexing issue resolution
- Log file analysis for large sites
Site Architecture & Internal Linking
How your pages link to each other tells Google what’s most important on your site. A weak architecture is one of the most common reasons strong content fails to rank.
- Full internal link audit
- Silo & topic cluster architecture planning
- PageRank flow analysis across key pages
- Anchor text diversification
- Broken internal link identification & fix
- Breadcrumb & navigation structure review
- Link depth reduction for buried content
Schema Markup & Structured Data
Schema markup tells Google — and AI search engines — exactly what your content means. It’s the difference between a plain search result and one with rich results, FAQ boxes and AI Overview citations.
- Schema implementation for service, product & FAQ pages
- Organization & LocalBusiness schema setup
- Article, Review & HowTo schema
- BreadcrumbList for navigation clarity
- Google Rich Result eligibility testing
- AI Overview & AEO-optimised content structure
- Structured data validation & error fixes
HTTPS, Redirects & Technical Health
Redirect chains, mixed-content errors and duplicate versions of your site quietly leak link equity and confuse crawlers. These are fixable — and fixing them often produces quick ranking improvements.
- HTTPS configuration & mixed-content audit
- Redirect chain detection & consolidation
- Canonical tag audit & correction
- 404 error identification & redirect mapping
- www vs non-www & trailing slash consistency
- HTTP header analysis (status codes, cache headers)
- Duplicate site version detection
Mobile & International SEO
Google indexes mobile first. If your mobile experience is broken or inconsistent with desktop, your rankings reflect that — even if desktop looks perfect.
- Mobile usability audit (Google standards)
- Mobile page speed assessment
- Viewport & responsive design checks
- Hreflang implementation for multilingual sites
- International URL structure review
- Country targeting settings in Search Console
Site Migration SEO
Redesigns, platform changes and URL restructures can wipe out years of rankings if not handled carefully. We plan migrations so your hard-earned traffic survives the move.
- Pre-migration crawl & ranking baseline
- Full redirect mapping (old URL to new URL)
- Canonical & internal link update planning
- Post-launch crawl verification
- Search Console re-submission
- 30/60/90-day ranking monitoring post-launch
What We Measure
Technical SEO Health Covers More Than Page Speed
Most tools give you a speed score and call it a technical audit. Real technical SEO covers six distinct health areas — any one of them can be the reason a page stalls at position 8 instead of reaching position 2.
- Crawlability: Can Google reach, follow and understand every important page?
- Indexation: Are the right pages indexed — and the wrong ones excluded?
- Page experience: Do LCP, CLS and INP all pass Google’s thresholds?
- Architecture: Does internal linking distribute authority to key pages?
- Structured data: Does schema markup match page content without errors?
- Security: Is HTTPS correctly configured with no mixed-content issues?

Our Process
How a Technical SEO Engagement Works
We don’t hand over a 300-row spreadsheet and wish you luck. Every engagement runs through the same clear process, from discovery to confirmed fixes.
Site Crawl & Data Collection
We crawl your full site, pull Search Console and Analytics data, and gather the complete technical picture before drawing any conclusions.
Issue Identification
We go through the crawl data manually — not just accepting what a tool flags. Some “errors” don’t matter. We know which ones do.
Prioritized Audit Report
You receive a report organized by impact — fixes that will move rankings first, low-priority housekeeping second. No noise, no filler.
Fix Implementation
We fix the issues directly — or provide developer-ready instructions if your team handles implementation. Either way, we follow through.
Verification
Every fix is verified in Search Console, recrawled and confirmed. We don’t mark something as done until it’s actually fixed in Google’s eyes.
Ongoing Monitoring
Technical issues reappear — new pages get added, plugins update, redirects break. We monitor for regressions and catch problems before they impact rankings.

FAQ
Frequently Asked Questions About Technical SEO
What is technical SEO and what does it cover?
Technical SEO covers everything that affects how search engines crawl, index, and rank your website — page speed, crawlability, indexation, site architecture, schema markup, HTTPS, mobile usability, redirects and more. It’s the foundation that on-page content and link building rely on to actually work.
How is a technical SEO audit different from a regular SEO audit?
A regular SEO audit covers on-page content, keywords, and backlinks alongside technical factors. A technical SEO audit goes much deeper on the engineering side — crawl behavior, JavaScript rendering, server response codes, log file analysis, structured data errors and Core Web Vitals — issues that require technical knowledge to identify and fix properly.
What are Core Web Vitals and do they affect rankings?
Core Web Vitals are three specific performance metrics Google uses as ranking signals: LCP (Largest Contentful Paint — how fast the main content loads), CLS (Cumulative Layout Shift — how stable the page is as it loads) and INP (Interaction to Next Paint — how responsive the page is to user input). Pages that fail these thresholds are at a measurable disadvantage in rankings.
My site looks fine. Do I still need a technical SEO audit?
Yes — most technical problems are invisible to users. A page can look and work perfectly in a browser while having crawl errors, duplicate content issues, broken canonicals or missing schema that affect how Google treats it. A visual check tells you nothing about indexation status or crawl depth.
How long does a technical SEO audit take?
A thorough audit for a small-to-medium site typically takes one to two weeks, depending on site size and complexity. Larger sites with complex architectures take longer. We don’t rush audits — a missed issue is a missed ranking opportunity.
Do you fix the issues or just report them?
Both. For issues that can be fixed directly in the CMS or settings, we fix them. For issues that require developer input, we produce clear, developer-ready instructions so there’s no ambiguity. Either way, every fix is verified in Google Search Console before it’s marked as resolved.
What is schema markup and why does it matter?
Schema markup is structured data added to your HTML that tells search engines — and AI tools like Google’s AI Overviews — exactly what your content represents. It enables rich results (FAQ boxes, review stars, breadcrumbs) in search results and makes your pages more likely to appear in AI-generated answers.
Can you help if we’re redesigning or migrating our website?
Yes. Site migrations are one of the most common causes of sudden ranking drops. We handle pre-migration crawls, redirect mapping, post-launch verification and monitoring — so your traffic survives the move instead of disappearing for six months while you figure out what went wrong.
How is your technical SEO different from running a site through a tool like Semrush or Screaming Frog?
Those tools generate data. We interpret it. A raw crawl export tells you what exists — it doesn’t tell you what actually matters for your rankings, what can safely be ignored, or what to fix first. Our value is in the analysis and the prioritization, not the crawl itself.
