Technical SEO services your rankings stand on.
Crawlability, indexation, site speed and Core Web Vitals, put right so search engines can reach, understand and rank every page. The groundwork that makes all your other SEO work.
Technical SEO is the backbone, not an afterthought.
If search engines cannot crawl, render and index your site efficiently, nothing above it works: content cannot rank, links cannot pass authority, and your organic visibility never improves. Technical SEO finds and fixes the issues holding everything else back.
It matters most at scale. The larger your site, the more a small efficiency gain in how Google serves your pages compounds into traffic and conversions, which is why technical SEO is so effective for big ecommerce catalogues.
Anicca’s SEO team have over 30 years combined experience with SEO, we’ve seen and diagnosed most issues a site could face. See below for just some of what our technical SEO services cover
What technical SEO covers
Five technical shifts that decide whether you rank.
Google rewards sites it can crawl cheaply and serve fast, and judges experience on real interactions. The technical bar keeps rising, and weak foundations quietly cap everything you do above them.
Core Web Vitals are an experience signal
INP replaced FID, and real-user LCP, INP and CLS feed Google’s page-experience signals. Lab scores are not enough; the field data is what counts.
JavaScript rendering is where pages disappear
Heavy client-side rendering can hide your content from crawlers. Server-side or edge rendering keeps pages search-accessible.
Crawl efficiency scales with your catalogue
On large sites, faceted navigation and parameter URLs waste crawl budget. Controlling what gets crawled and indexed is where the gains are.
Indexation is now selective
Google indexes less of the web by choice. Thin, duplicate or low-value URLs get left out, so signalling the right canonical set matters more than ever.
Structured data feeds AI answers too
Clean schema helps both rich results and the systems behind AI Overviews understand and cite your content.

What brands ask about technical SEO.
What is technical SEO?
Technical SEO is the practice of making sure search engines can crawl, render and index your site. Google weights on-page factors like headings, URL structure, metadata and content, but if those elements are not search-accessible, they cannot be valued for ranking. Issues like slow loading or incorrect indexation signals quietly cap your organic traffic.
What is a technical SEO audit?
An audit is your roadmap to a more search-accessible site. It draws on Search Console, dedicated crawlers and manual checks, and may recommend Core Web Vitals improvements, navigation and rendering changes, robots and sitemap tweaks, schema deployment, canonical and indexation fixes, and notes on duplication or content quality, including issues unique to your site’s architecture.
Why is technical SEO important?
It is the foundation everything else stands on. Without a search-accessible site, content is less effective, and inbound links and digital PR have no impact if Google is blocked from indexing your pages. The larger your site, the more technical SEO multiplies your existing gains by helping Google reach more of your content more easily.
How well does technical SEO work for ecommerce?
Particularly well. Large stores have hundreds or thousands of product pages, each a ranking opportunity, and often suffer indexation issues around filtered or faceted navigation. Serving those pages more efficiently in search, and indexing the right ones, tends to drive meaningful traffic and conversion uplift.
How long does a technical audit take?
For most sites we complete an audit in around two days; larger sites can take up to five, though that is rare. Each separate domain counts as its own site, so a .co.uk and a .com would each need their own audit. We always agree an up-front cost that does not change without reason.
