Robots.txt change alerts
We continuously watch your robots.txt and immediately warn you if it changes — especially if a Disallow suddenly appears that blocks the site or important sections from search engines. A single accidental line after a deploy can drop the site from results, and it is usually noticed only from a traffic drop weeks later. Honestly upfront: this is an ongoing service that detects a change and notifies — it does not edit robots for you and does not manage indexing — fixing the file is up to you or your team.
Robots.txt change alerts — overview

Robots.txt change alerts is an ongoing (monthly) service: we regularly download your robots.txt and compare it against a fixed baseline. If the file changes — a Disallow/Allow appears or disappears, a directive for an important section changes, the sitemap link is gone, the file becomes unavailable or returns an error — you immediately get an alert with exactly what changed (a diff). Special attention goes to dangerous changes: an accidental Disallow: / or blocking key sections after a deploy, migration or CMS edits is a classic cause of a sudden drop from search. Honestly about the essence: this is detection and alerting, NOT editing robots and NOT managing indexing — we do not edit the file for you and do not "return the site to the index"; the fix is made by you or your team, our alert only catches the problem on the day it appears rather than weeks later from a traffic drop. And honestly about robots itself: it is an instruction-hint for search robots, not a hard command — well-behaved bots respect it, but indexing overall is decided by the search engine, and we do not guarantee it. False positives are possible on your own planned edits — so we update the baseline by agreement; if several teams edit robots there will be many planned alerts, and we tune the sensitivity together with you to avoid "noise". The check needs stable access to the file over HTTP(S) — hosting or firewall limits are possible. Coverage is the configured domains and subdomains; new ones are added together. Someone must react to an alert. An important boundary: this is control of robots.txt changes, not an SEO audit, not indexing setup and not sitemap management (there are separate alerts for the sitemap). If the site is tiny and robots is not touched for months, continuous monitoring may be overkill, but the cost of a mistake here is high and the service pays off with a single caught "Disallow: /". Picture this: instead of "search traffic collapsed, and two weeks later it turned out that after the release robots accidentally blocked the whole site" you get an alert on the deploy day and restore the line in a minute. The base price starts from 4,000 ₽ per month; it depends on the number of domains.
Problems we solve
- You fear robots accidentally blocking the site from search after a deploy.
- No one tracks robots changes, and the cost of a mistake is all your traffic.
- You learn about the problem only from a search-traffic drop weeks later.
- Several people/CMS edit robots, and it is easy to break something unnoticed.

FAQ
Will you fix robots if it blocked something?
No. We detect a change and immediately notify with a diff, but we do not edit the file for you and do not manage indexing. The fix is made by you or your team — our alert is there so you can do it on the day of the problem rather than weeks later.
Do you guarantee the site will be in the index?
No. robots.txt is an instruction-hint for robots, not a command; indexing overall is decided by the search engine. We only ensure robots does not accidentally block something important and notify of changes — but we do not guarantee indexing itself.
Will there be false alerts on our own edits?
Your planned changes will first show a divergence from the baseline — that is expected. We update the baseline by agreement when you make deliberate edits so real alarms do not get lost in the noise.
