Last week we wrote about why we stopped reporting weekly performance deltas. A single week-on-week number was hiding what actually happened in between, so we replaced it with a 7-day score series and let the digest reason over the full week instead of two snapshots. That was a step in the right direction, but not the whole answer.

We’ve improved SiteVitals performance reporting so it does more than tell you a metric is slow. It now helps explain why, what is involved, and what to investigate first.

A single week-on-week number sounds precise. For PageSpeed in particular, the results over the week can vary hugely. Taking a single snapshot and deriving performance off the back of 2 values can be very missleading and misrepresent the actual situation.

Agentic AI browsing has gone from a research demo to a line item on your traffic logs in about eighteen months. Claude, ChatGPT, Perplexity's Comet, and a growing list of purpose-built agent frameworks are now visiting websites not to read them for a human, but to act on a human's behalf — filling in a form, checking a price, calling an API, deciding whether your site is even worth the trip. That's a different audience with different needs, and most of the web hasn't caught up.

We've added a small but useful check to SiteVitals seo monitoring: viewport meta tag detection. This single tag tells a mobile browser how to render the page. Without it, phones default to showing the page as if it were on a desktop screen, then shrinking the whole thing down to fit. It sounds more technical than it is. Here's what it means.

An XML sitemap is one of the last things most people think about when it comes to their website. It's just something that most CMS platforms generate automatically. You tick the box and move on. For the majority of sites, it is never really reviewed again - perhaps once when you submit it to Google Search Console, but that's probably it. But the audience for your sitemap has changed significantly recently, and it probably deserves more respect.

Internal linking has always been one of those SEO fundamentals that gets mentioned in every checklist and then, largely, ignored. It sits below the fold of most audits — something to fix if you have time, after the title tags and the schema and the Core Web Vitals. We think that's the wrong priority order, and we've built a new check into SiteVitals to make the case.

When we built the original SEO dashboard, the brief was straightforward: flag the technical issues that hurt search rankings. Missing title tags. Broken links. Noindex directives left in by mistake. But the landscape has shifted over the past few months and the list of things site owners and administrators need to consider to appear in AI-assisted search keeps growing and getting more complicated.

The SiteVitals AI Audit extension for Chrome is now live in the Chrome Web Store — same audit panel, same instant feedback, now in the browser most of you are actually using day to day.

Web agencies are sitting on a stream of legitimate maintenance work their clients need but never ask for. Here's how AI is making that conversation easier to start.

We're pleased to announce that the SiteVitals AI Audit extension for Firefox has been approved and is now available on the Mozilla Add-ons store.

Semantic HTML isn't just good practice, it's how AI systems identify, trust, and cite your content. Here's what we now check and why it matters.
