SEO & retail data
Google's November 2026 core update is rolling out across every site and language in the fortnight before Black Friday. The steadiest move for UK online shops is to leave rankings to settle and use the time to make product pages load faster on phones.
What Google has started
Google has begun rolling out its November 2026 core update, as Search Engine Roundtable reported. Google expects the rollout to take about two weeks. It describes it as "a regular update designed to better surface relevant, satisfying content for searchers from all types of sites."
PPC Land notes that every site in every language is in scope from 10:07 Pacific on November 10. That timing puts the rollout right in the run-up to Black Friday and Cyber Monday, the busiest selling window of the year for many UK retailers.
During a core update, rankings can move day to day. Pages may drop, recover and shift again before the rollout finishes. A snapshot taken halfway through often looks different from the one taken a week after it ends. For that reason, rewriting product or category pages mid-rollout means reacting to numbers that are still changing.
Why phone speed is the better use of the time
While the update settles, the safer work is on what shoppers notice when they arrive. Slow loading on a phone is high on that list. A shopper who waits too long for a product page may simply go elsewhere, whatever the page's ranking.
Online shopping matters to UK retail. Online accounted for 28.3% of UK retail sales in September 2026, according to ONS figures in Sayu's study. That figure covers one month and all types of retailer, so individual shops will see their own mix.
On speed, 70% of the 491,119 websites UK Chrome users visited on phones in September 2026 passed Google's Core Web Vitals, Sayu's study found. The rest were too slow to load, too jumpy or too slow to respond for at least a quarter of visits. On phones, loading speed is the test these sites fail most often: 80.8% have a good loading score, against 89.4% for responsiveness to taps and 90.2% for layout stability. These figures come from Chrome users only and cover all kinds of websites, so they describe the wider web rather than shops alone.
Speed matters here because it affects sales and customer patience. Nothing in Google's announcement says slow sites will be hit by this update.
What this means for UK businesses
- Wait before rewriting. Rankings can keep moving until the rollout ends. Judge any changes on data from after it finishes.
- Keep a record. Note your main pages' positions and traffic now, so you can compare them once things settle.
- Test on a real phone. Open your best-selling product and category pages on a mobile connection and see how long they take to show.
- Fix the heaviest pages first. Large images, autoplay video and extra scripts are common causes of slow loading.
- Freeze big site changes close to the sale. Small speed fixes are lower risk than redesigns in the busiest week.
