Semrush rebuilt SEOquake, its free Chrome extension for page-level SEO checks

Semrush shipped a rebuilt version of SEOquake on 2026-09-09, its free Chrome extension for running page-level SEO checks without leaving the tab. The update ships as a Chrome Web Store push, so anyone who already has the extension gets it on the next background update.

The count of on-page checks moves from 22 to 28. The new ones sit alongside the old on-page items (title, meta description, headings, image alt, URL structure, internal links, keyword density) and cover technical and social signals: HTTP status and HTTPS, canonical tags, robots and indexing directives, Schema.org markup, viewport and responsive design, Open Graph, and Twitter Cards. The Audit view groups them by category and shows character counts on titles and meta descriptions.

Two views, and a bar that stays open

The rebuilt extension separates a quick check from a deeper report. Quick View is the popup that opens on click and gives a snapshot across Page Info, Content, Audit, Schema, and Semrush tabs. Full Report opens the full page-level analysis, with dedicated panels for auditing, keyword density, links, comparisons, and Semrush data.

SEObar is back after being left out of an earlier rebuild. It is the on-page bar that pins selected metrics to the top or bottom of every page as you browse, without needing to reopen the popup. Semrush says SEObar was one of the most-requested features to return. You choose which metrics show, where the bar sits, and whether it uses a light or dark theme.

The Links report separates internal from external, and shows anchor text, follow or nofollow status, and HTTP status per link. This is the outbound view from the page itself, not backlinks pointing at it. Keyword density covers phrases from one to four words, flagging whether each term appears in the title, description, or H1. Semrush is careful to state that keyword density is not a ranking formula and there is no ideal percentage to target.

Exports move to CSV for keyword density, links, and comparison data, and PDF for the audit report.

What was cut, and where the data went

Several metrics were dropped because the underlying services stopped providing the public data. Google Cache dates went with Google retiring cache links in 2024. Index counts from Google, Yahoo, Bing, Yandex, and Baidu were pulled, along with Yandex IKS. Older on-page checks for meta keywords, Flash, frames, and microformats were also removed as no longer meaningful.

The SERP overlay is not in this release, and neither is on-page nofollow or noindex highlighting. There are no Firefox or Opera builds this time; Chrome is the only officially supported browser, though the extension installs in other Chromium browsers (Edge, Brave, Arc). Semrush has not given a timeline for the missing pieces, and says user feedback will inform priority.

Semrush metrics inside SEOquake include Semrush Rank, an estimate of United States organic traffic, Traffic Cost, and backlink data, with the depth depending on whether the user is connected to a Semrush account and which plan is on it. The core page-level analysis stays free without an account.
