Title tags
Length, keyword loss and truncation risk scored on every change.
SiteGauge watches every on-page signal that moves rankings (title tags, canonicals, noindex, headings, schema, robots.txt and sitemaps) and tells you, in plain English, the moment something drifts.
Paste any URL and watch SiteGauge capture it. Pick the area to track and set an alert, right here. No sign-up needed to look.
Most change monitors just diff text. SiteGauge understands SEO, so a removed canonical screams while a reworded sentence stays quiet.

When a meaningful SEO change is detected, SiteGauge sends the diff to Claude and gets back a plain-English summary, the likely ranking impact, and an importance score from 1 to 10, so a junior can triage and a director can act.
The H1 on /pricing changed from "Simple, transparent pricing" to "Plans", removing the primary keyword, and a noindex tag was added. The noindex will drop this page from search within days. This looks unintended, likely a template regression. Recommend reverting the noindex immediately.
No agents, no proxies, no code. Paste a URL and you are monitoring.
Paste a page, a list, or a whole sitemap. Pick the SEO workflow so on-page signals are weighted above body copy.
A cheap hash check runs first; full render, screenshot and AI analysis only fire when a real, scored SEO change is confirmed.
An alert lands in email, Slack, Teams or a Google Sheet, with an AI summary, an importance score and a before/after diff.
Watch every client site for regressions, prove value with white-label change reports, and never get blindsided by a dev deploy.
Get told the moment a release strips a canonical or noindexes a template, weeks before it shows up in Search Console.
Catch accidental title and meta rewrites from the CMS, and keep your structured data and internal links intact.
By the time GSC shows the drop, the change is weeks old. SiteGauge tells you the day it ships.
