Rewrite the title tag
Why
The page already ranks on page one and gets seen, but few searchers click. A title that matches the search better may turn more of those impressions into clicks.

Click-through drop · /pricing
The result is shown as often and as high as before, but fewer searchers choose it. The snippet is the likeliest place to look.
Clicks may return if the snippet is the cause. Measured 21 days after you mark it done.
Technical SEO · /blog/eu-vat-guide-2026
Without one, search engines have to guess which URL is the main version. Variants such as ?utm_source=newsletter can end up competing with it.
Ranking signals can consolidate on one URL. Measured 28 days after you mark it done.
Technical SEO · /services/accounting
A link on this page points to /old-tariffs, which returns a 404. Visitors and crawlers reach a dead end.
Visitors and link signals reach a live page. Measured 56 days after you mark it done.

Enter your domain. We read your robots.txt, your sitemap and your homepage, and show what can be improved technically.
One page, without signing in. A scan of all your pages, with your Search Console data, is part of the trial.
Honesty about uncertainty is a product rule. Every result is held to the same minimum.
Only 180 impressions in the baseline, below the minimum of 400. Lastmod says “not enough data” instead of showing a percentage.
900 impressions and a clear lift, but a second task was completed on the same page in the same window. The result is shown, flagged, and left out of the impact total.
2,100 impressions in the baseline, well above the minimum, and no other change on the page. The difference is large enough to report.
Illustrative examples, not customer data.
The band on a result says how reliable the measurement is, not how sure Lastmod is of a cause. It is not a claim of statistical significance. The thresholds are starting values that will be tuned as real data comes in.

Each step runs at its own pace. The figure says how often or how long; the window shows what Lastmod does in that time.
1 · Scans
Your Search Console data comes in every day. The crawler also walks your site every 7 days and records what is in the HTML. It checks your 25 pages with the most impressions and pages with an open task every time, a page that does not change less and less often, down to once every 14 days. Fixed rules turn that into findings, not AI.

2 · Check
You change your site yourself and mark the task done with the new text. About 30 minutes later Lastmod fetches your live page and looks for that text in it. If it's there, the measurement starts. If it can't check automatically, it says so.

Then Lastmod says so, rather than assuming.
3 · Measurement
The 28 days before form the baseline. For a title the measurement window runs 21 days, plus 3 days for Search Console to settle. With too little traffic, Lastmod says so instead of showing a percentage.

Lastmod asks ChatGPT and Google AI Mode the questions you approve, a few times a week, and counts how often your website is named or used as a source.
Data vs proof
Most tools stop at a dashboard of scores and a long list sorted by severity. Lastmod ranks what to fix, checks that it is live and then measures what changed.

Compare every limit →Audit tools typically stop at the list of issues. Lastmod ranks what matters, explains why, says how sure it is, and afterwards measures what happens to your clicks.
Technical checks, such as missing titles, canonical tags and broken internal links, only need your verified domain and an XML sitemap, so you can browse those findings without Search Console. Search Console access to your whole domain also works instead of a DNS record. You can turn a technical finding into a task without it; Lastmod then only checks the implementation, not the clicks. Measuring the result in clicks does need a working connection, which also unlocks quick wins, click-through drops and Core Web Vitals checks. You connect it during setup.
No. Lastmod never edits your site; you make the change yourself. If you opt in to IndexNow, Lastmod notifies Bing and other search engines that use it after you mark a task done. That is a notification, not an edit, and Google does not use IndexNow.
Your database and the application run in the EU. For AI analysis we send page titles, meta descriptions, headings, search queries and measurement results to Anthropic in the United States, under EU Standard Contractual Clauses. A few other providers handle limited technical data outside the EU. Every provider is listed on the sub-processor page.
After the free trial your account becomes read-only and your data stays. We never asked for a card, so nothing is charged. To continue, choose a plan in the app: businesses in the EU subscribe and pay there; otherwise contact us and we activate a plan. On Starter, analysis runs weekly instead of daily and history is kept for 90 days; Pro keeps daily analysis.
