The Hidden Back-End
AI agent series · the hidden back-end

What's really running
beneath your website.

When you visit a website, you see a homepage. What you don't see are the technical mechanics running behind it, each one affecting whether Google ranks that site on page one or page ten, whether visitors stay or bounce, and whether the business grows.

The website iceberg

Most of your website is below the waterline.

The website icebergAbove the waterline, what owners see: homepage design, contact form, blog posts, navigation menu and photo gallery. Below the waterline, what an audit checks: Core Web Vitals, schema markup, crawl budget, canonical tags, hreflang tags, robots.txt and sitemap, image optimization, redirect chains and JavaScript rendering.ABOVE THE WATERLINE · WHAT OWNERS SEEBELOW THE WATERLINE · WHAT AN AUDIT CHECKSHomepage designContact formBlog postsNavigation menuPhoto galleryCore Web VitalsSchema markupCrawl budgetCanonical tagsHreflang tagsrobots.txt and sitemapImage optimizationRedirect chainsJavaScript rendering
Nine invisible mechanics

Most owners have never heard any of these words.

Core Web Vitals
LCP, INP and CLS
Loading, responsiveness and visual stability scores. Google uses them as part of its page experience signals. INP replaced FID as a Core Web Vital in March 2024.
Schema markup
Structured data
Code that tells search engines what a page is about, which enables rich results such as stars, FAQs and events.
Crawl budget
What gets visited
How much of a large site Google chooses to crawl. Waste it and important pages can go unvisited.
Canonical tags
One page, one address
Tell Google which version of a page is the real one, so duplicate URLs don't split your ranking signals.
Hreflang tags
For multilingual sites
Tell Google which language version to show to which user.
robots.txt and sitemap
The map for crawlers
Misconfigured, they can block your best pages from ever being indexed.
Image optimization
Size, format, alt text
Oversized images slow pages and hurt Core Web Vitals. Alt text helps accessibility and image search.
Redirect chains
Every extra hop costs
Chains slow pages and make crawling harder. They can usually be collapsed to a single redirect.
JavaScript rendering
What crawlers can read
If a search engine can't render your scripts, it may not see your content.
What we check

An audit report, in plain English.

  • Page speed and Largest Contentful Paint
  • Structured data coverage across pages
  • Redirect chains
  • Broken internal links
  • Images missing alt text
  • SSL certificate status and expiry
  • Pages blocked in robots.txt that shouldn't be

Each finding goes into your approval queue with a suggested fix. Nothing on your site changes until you approve it.

Retail conversion from speed
+8.4%
A 0.1-second improvement across four mobile speed metrics raised retail conversion rates by 8.4% (and travel by 10.1%) in a study of European mobile sites.

What happens when these break, and nobody notices
Slow pages
Sales leak quietly
Small speed losses across every step of a visit add up to lost conversions, and nobody gets an alert for it.
Missing structured data
Harder for machines to read
Without it, search engines and AI systems have to guess what your page is about, and you are less likely to get rich results.
A robots.txt slip
Pages drop out of search
One wrong line can block crawling of entire sections of a site, often noticed only when traffic falls.
Duplicate versions
Split signals
www and non-www, or http and https, competing as separate sites can split the authority you should own outright.
