How Algorithms Affect Your Website (2026 Guide)
A visitor lands on your website, waits three seconds for it to load, and leaves. You never find out they were even there. Google notices the same thing happening across thousands of visitors, and quietly starts showing your site to fewer people. Neither of them sent you an email to explain why.
In 18 years running Optimise Your Marketing from Cromford Mills in Derbyshire, I have lost count of the number of East Midlands businesses who assumed a drop in website enquiries was a marketing problem, when it was actually a two-second delay in page load time quietly working against them on every single visit.
This post builds on a point from our guide to how algorithms fit into every part of the BIG12: Google and your visitors now judge your website through largely the same lens. Here is exactly what that lens is measuring.

For years there was a gap between what made a website rank well and what made a website convert well. That gap has almost closed. Google's ranking system now weighs page speed, mobile responsiveness, clear navigation and low friction because these are exactly the things that determine whether a real visitor stays or leaves. A website built for people is now, largely, a website built for the algorithm too.
What Core Web Vitals Actually Measure
Core Web Vitals are the specific algorithmic signals Google bakes directly into its ranking system, and they break down into three measurable parts.
Loading speed
Google measures how long it takes for the largest visible element on a page, usually a hero image or headline, to fully load. Slow-loading pages are penalised in rankings and abandoned by visitors at almost exactly the same rate.
Responsiveness
This measures how quickly your site reacts the moment someone taps a button or link. A page that looks loaded but lags on the first interaction creates exactly the kind of friction Google's algorithm is built to detect and downgrade.
Visual stability
Nothing frustrates a visitor faster than a page that shifts under their thumb as images and adverts load in. Google tracks this directly, and penalises pages where content jumps around after the visitor has started reading.
Google is not grading your website on a curve anymore. It is running the same test a frustrated visitor runs every time they land on a slow page, and it is grading you exactly the same way they would. Stuart Baddiley, Optimise Your Marketing
The On-Site Algorithms Nobody Thinks About
Your website's own internal search bar runs an algorithm too, matching what a visitor types to what you actually have on the site, and a poor match sends them straight to your competitor's search results instead. Recommendation algorithms, the "you might also like" or related content sections, quietly decide whether a visitor sees one page and leaves or explores five and enquires. Most businesses never audit either of these, despite building their entire acquisition strategy around getting people to the site in the first place.
Clear navigation and low friction checkout or enquiry forms feed directly into these same systems. A confusing menu structure does not just frustrate a human, it makes it harder for both your own on-site search and Google's crawlers to understand what your site is actually about.
When a Derbyshire service business fixed speed before spending on ads
A client across the East Midlands was about to increase ad spend to fix a falling enquiry rate. Before we touched the ad account, we rebuilt their site for speed and mobile responsiveness, cutting load time by more than half. Enquiries rose 34% from existing traffic alone, before a single extra pound was spent on ads.

Website sits right next to SEO, Google and Lead Generation in the BIG12, and a slow or confusing site quietly undermines all three at once, no matter how good the traffic driving people there is. This is exactly what we build for in our Squarespace builds for Derbyshire and East Midlands businesses, and it is why we teach it as one connected system in our online marketing training, alongside our wider guide to where algorithms fit into every part of the BIG12.

Knowing that page speed and mobile responsiveness matter is the easy part. Actually auditing every page, compressing images, rebuilding a confusing navigation structure, and testing on real mobile devices, that is where most Derbyshire and East Midlands business owners run out of time.
That is the gap we close. In 18 years of applying the BIG12 for UK SMBs, the websites that convert consistently are never the ones with the cleverest design, they are the ones built to load fast and get out of the visitor's way.
If your website has felt slower than it should, or enquiries have quietly dropped, it is worth finding out why before you spend another penny driving traffic to it.
