Let’s find the technical issues silently suppressing your rankings and create a fix roadmap.
Technical SEO is the infrastructure everything else is built on. Get it wrong and nothing else matters.
Technical SEO is the practice of ensuring your website can be efficiently crawled, correctly indexed, and properly understood by search engines. Without a sound technical foundation, even the best content and most powerful backlinks will underperform — because Google cannot reliably access, interpret, or rank your pages.
Most websites we audit have critical technical issues that have been quietly suppressing rankings for months — sometimes years — without anyone noticing. A free 45-point technical SEO audit from Keyphrased will tell you exactly what is holding your site back, and in what order to fix it.
Get your free technical SEO audit →If Google’s crawler cannot reach your pages — because of robots.txt errors, redirect chains, broken internal links, or crawl budget waste — those pages cannot rank. Crawlability is the first thing we fix.
A page that is crawled but not indexed cannot rank. Canonical tag errors, noindex directives, duplicate content, and thin pages all cause indexation failures. We audit every page and fix the signals that prevent indexation.
Google uses Core Web Vitals (LCP, INP, CLS) as ranking signals. Slow pages lose rankings and users simultaneously. We diagnose and fix the specific performance bottlenecks suppressing your scores.
URL structure, internal linking hierarchy, breadcrumb schema, and information architecture all signal to Google what your most important pages are. Poor architecture dilutes ranking power across your entire site.
Every technical SEO service your site needs — in one specialist team.
From one-off technical audits to ongoing technical oversight — everything we do is prioritised by the ranking impact it will have on your specific site, not by how complex or impressive it sounds.
A 45-point forensic audit covering crawlability, indexation, Core Web Vitals, site architecture, canonical strategy, schema markup, internal linking, page speed, mobile usability, and AI search readiness — delivered as a prioritised action plan, not a spreadsheet of issues without context.

We identify the specific bottlenecks — image format, server response, render-blocking resources, layout instability — and fix them at the root cause.
Get started →Robots.txt auditing, crawl trap identification, redirect chain consolidation, crawl budget analysis via log file review, and sitemap optimisation — ensuring Google spends its crawl budget on the pages that matter and discovers new content faster.
Get started →Implementation and auditing of Schema.org structured data — including Organisation, LocalBusiness, Product, FAQPage, Article, BreadcrumbList, and sector-specific schemas. Rich results eligibility, Knowledge Panel enhancement, and AI search citation signals all flow from correct structured data.
Get started →Full technical SEO coverage for platform migrations, domain changes, URL restructures, and CMS switches. Pre-migration auditing, redirect mapping, crawl verification, and post-migration monitoring — protecting your organic rankings throughout the transition and recovering any losses fast.
Discuss your migration →Forensic diagnosis of traffic drops caused by Google core updates, HCU, Panda-style content issues, or Penguin-style link penalties. We identify the specific cause — technical, content, or link-related — build a prioritised recovery plan, and track recovery through subsequent algorithm updates.
Discuss your recovery →Information architecture review, silo structure planning, internal link hierarchy analysis, breadcrumb implementation, and URL structure consolidation. The way your site is organised directly influences how Google distributes ranking authority — and most sites do this badly.
Get started →Canonical tag strategy, noindex/nofollow auditing, duplicate content identification and consolidation, hreflang implementation for international sites, and pagination handling. We ensure Google indexes exactly the pages you want indexed — and deindexes the pages that are cannibalising rankings.

Every CMS and e-commerce platform has its own technical SEO quirks, traps, and limitations. We know them all — including the issues that platform-specific SEO plugins miss entirely.
Plugin conflict auditing, Yoast/RankMath configuration review, theme rendering issues, JavaScript-dependent content problems, and the crawl waste that default WordPress configurations generate at scale.
Faceted navigation crawl traps, duplicate product pages from variant URLs, collection page canonicalisation, Shopify’s default robots.txt limitations, and the pagination issues that cause Shopify stores to waste crawl budget at scale.
Product and category architecture, tag and attribute page indexation control, WooCommerce-specific duplicate content issues, shop page optimisation, and the crawl inefficiency that large WooCommerce catalogues generate without proper technical configuration.
Enterprise-level crawl configuration, layered navigation canonicalisation, multi-store hreflang setup, page speed optimisation for Magento’s notoriously heavy default configuration, and technical SEO for large catalogues of 10,000+ SKUs.
Webflow CMS SEO configuration, headless architecture technical SEO (Next.js, Gatsby, Nuxt), server-side rendering vs. client-side rendering for search engine accessibility, and the indexation challenges specific to JavaScript-first architectures.
Technical SEO consultancy for bespoke-built platforms, custom e-commerce systems, and enterprise CMS environments. We work directly with development teams to implement technical recommendations — with developer-ready specifications for every fix.
HubSpot CMS technical configuration, blog pagination and canonical settings, HubSpot-specific crawl issues, integration with Google Search Console and Analytics for full technical visibility, and pillar-cluster architecture setup.
Maximising technical SEO performance within the constraints of website builders — including the crawl inefficiencies, JavaScript rendering challenges, and canonical issues inherent to Squarespace and Wix that require specific workarounds.
The five technical SEO problems we find in almost every audit — and how we fix them.
These are not theoretical issues. They appear in the vast majority of technical audits we run — often on sites that have already had SEO work done by a previous agency.
Tag pages, author archives, internal search result pages, and filtered URLs eating crawl budget that should be directed at your commercial pages. Google never reaches your most important content because it is too busy crawling junk.
LCP above 4 seconds, layout shifts on mobile, poor INP scores on interactive pages — all directly suppressing rankings on Google’s page experience ranking signals. Most sites fail CWV on their most important commercial pages, not their blog posts.
Self-referencing canonicals missing, cross-domain canonical conflicts, pagination handled incorrectly, and product variant URLs all pointing to themselves rather than the canonical version — splitting link equity and rankings across duplicate pages instead of consolidating them.
Pages that exist on the site but receive no internal links — so Google either never finds them or assigns them negligible authority. Particularly common on e-commerce sites with large catalogues and on sites that have migrated without proper redirect mapping.
Sites with zero Schema.org implementation are invisible to the structured signals AI engines use to identify citation-worthy content. As Google AI Overviews, ChatGPT, and Perplexity handle more commercial queries, structured data moves from nice-to-have to non-negotiable.
From audit to clean bill of technical health — four steps.
We do not hand you a 200-row spreadsheet of issues and leave you to figure out what to fix first. Every audit is delivered as a prioritised action plan — ranked by ranking impact, not technical complexity.
Crawlability, indexation, Core Web Vitals, schema markup, site architecture, canonical strategy, duplicate content, mobile usability, and AI search readiness — assessed across your entire site and delivered in 48 hours.
Every issue ranked by its projected impact on organic performance — not alphabetically, not by severity alone, but by the specific revenue and ranking uplift fixing it is likely to deliver for your site and competitive landscape.
We implement fixes directly where possible, or provide developer-ready technical specifications for your development team. Every fix is verified post-implementation against Google Search Console, PageSpeed Insights, and crawl data.
Monthly technical health checks catch new issues before they suppress rankings — CMS updates, developer changes, and new content can all introduce regressions. Ongoing clients get continuous monitoring and a monthly technical health report.
Technical SEO fixes that moved the needle — with numbers.
Results from active clients. Names anonymised under NDA — full case study walkthroughs available on request.
A WooCommerce store had 18,000 pages indexed — but only 2,100 were real products or categories. Tag pages, internal search results, and attribute URLs were consuming the entire crawl budget. We implemented noindex directives across low-value page types, restructured the sitemap, and consolidated canonical tags across product variants. Google re-crawled priority pages within 6 weeks and organic traffic tripled within 4 months.
A B2B SaaS company had migrated to a headless Next.js architecture without verifying that Google could render their JavaScript-dependent content. 60% of their product and feature pages were in Google’s index but rendering as blank pages. We implemented server-side rendering for SEO-critical pages, fixed structured data injection, and rebuilt their sitemap. Rankings recovered within three Google crawl cycles.
A legal services firm was ranking on page 2 for their highest-value practice area terms despite strong content and backlinks. Technical audit revealed LCP above 6 seconds on mobile and significant CLS from unoptimised hero images and a late-loading cookie banner. We fixed image formats, implemented lazy loading, eliminated render-blocking resources, and resolved the cookie banner CLS. All 11 target pages entered the top 3 within 10 weeks.
What clients say about our technical SEO work — with the results to back it.
Technical SEO done properly is invisible to end users and transformative for rankings. Here is what clients experienced.
“We had spent 18 months on content and links and rankings barely moved. Keyphrased ran a technical audit and found that 60% of our pages were not being properly indexed. Three months after the technical fixes, we saw more ranking movement than in the previous year and a half combined.”
“Our agency before Keyphrased had done ‘technical SEO’ — but when Keyphrased audited the site they found 47 critical issues that had been missed or created by the previous work. The audit report was the clearest technical document I have ever received from any agency.”
“We were migrating from Magento to Shopify and were terrified of losing our rankings. Keyphrased handled the full technical SEO migration — redirect mapping, crawl verification, structured data — and we came out the other side with rankings intact and Core Web Vitals improved.”
Technical SEO questions — answered plainly.
Technical SEO can feel opaque. Here is plain-English clarity on the questions we get most. Can’t find yours? Just ask.
Ask us anything → Usually replied to within 2 hoursTechnical SEO is the practice of ensuring that search engines can efficiently crawl, render, index, and understand your website. While on-page SEO focuses on content and keywords, and off-page SEO focuses on links and authority, technical SEO addresses the infrastructure layer — site architecture, page speed, crawlability, indexation, structured data, and mobile performance. Without a sound technical foundation, content and link work will always underperform because Google cannot reliably access or interpret your pages.
Technical SEO typically shows results faster than content or link work because it removes barriers rather than building new assets. Crawl fixes and indexation corrections can show impact within 4–8 weeks as Google re-crawls affected pages. Core Web Vitals improvements can influence ranking within 2–4 weeks once Google’s data refreshes. Migration-related fixes can show impact within 2–6 weeks depending on crawl frequency. The key variable is how frequently Google crawls your site — which itself is a function of your domain authority and content update frequency.
It depends on the platform and the fix. Many technical SEO tasks on WordPress, Shopify, and Squarespace can be implemented without developer involvement and we handle these directly. For more complex fixes — server-side rendering changes, Core Web Vitals at code level, hreflang implementation at scale, or custom schema injection — developer access is required. If you do not have an in-house developer, we work with a network of trusted developers and can scope, specify, and manage implementation at an agreed day rate.
Our 45-point technical SEO audit covers: crawlability (robots.txt, crawl traps, redirect chains, crawl budget), indexation (canonical tags, noindex directives, duplicate content, sitemap accuracy), Core Web Vitals (LCP, INP, CLS across mobile and desktop), site architecture (URL structure, internal linking, breadcrumbs), schema markup (structured data completeness and validity), mobile usability, HTTPS and security, page speed, international SEO (hreflang where applicable), and AI search readiness (structured data for GEO). It is delivered as a prioritised action plan — ranked by impact — not a raw data export.
Yes — but JavaScript-heavy sites require specific technical SEO expertise that many agencies lack. Google’s crawler uses a two-wave rendering process for JavaScript: it crawls first and renders later, meaning JS-dependent content can take days or weeks to be indexed. We audit Google’s rendering of your JS content directly using the URL Inspection tool and Fetch as Google, then recommend the right rendering strategy — server-side rendering (SSR), dynamic rendering, or progressive enhancement — based on your specific framework and content requirements.
E-commerce sites face specific technical SEO challenges that do not apply to most other site types: faceted navigation crawl traps (filter URLs generating millions of near-duplicate pages), product variant URL canonicalisation, out-of-stock page management, category page pagination, Product schema for rich results, and crawl budget management at scale. These issues can cause Google to waste its entire crawl allocation on low-value filter pages — leaving commercial category and product pages under-crawled and under-ranked. Technical SEO for e-commerce is a specialism in itself.
Website migrations are one of the highest-risk technical SEO events a site can undergo. We provide pre-migration auditing (benchmarking current rankings, crawl data, and indexation), redirect mapping (ensuring every old URL redirects correctly to its new equivalent), crawl verification (confirming Google can access the new site structure), structured data transfer, and post-migration monitoring for 90 days to catch and resolve any ranking drops before they compound. A poorly managed migration can cause 50–80% ranking loss that takes 12+ months to recover from.
