SEO changes monitoring for your websites

SEOtto is an SEO monitoring tool. It crawls your site as often as every hour, compares each page with the last crawl, and alerts you when a change can cost you search traffic: a noindex tag, a robots.txt block, a broken sitemap or a changed title or canonical. You fix it before Googlebot comes back.

Free SEO checker. Paste any URL to test it the way a search engine reads it:

What SEOtto does.

SEOtto checks your website for problems that can remove pages from Google. It runs the same checks every day or every hour, compares the results with the last crawl, and tells you what changed.

01

Add your site

Enter your website's address. SEOtto finds your pages in your XML sitemap, or follows your internal links if there is no sitemap. There is no plugin to install and no Google account to connect.

02

SEOtto checks every page

It reads each page the way Googlebot does: the status code, noindex tags, the canonical, the title, the meta description and the H1. It also reads robots.txt, the sitemap and the SSL certificate. This runs every day, or up to every hour on Pro and Agency.

03

You get an alert when something breaks

By email, Slack or webhook. The alert says which page broke, what changed and how to fix it. When nothing changes, SEOtto sends nothing.

Overview
The demo account has four made-up sites. The site with the worst problems is at the top. Fix first, on the right, lists the six critical problems.

Technical SEO issues, found before Search Console reports them.

Search Console shows an error after Google has crawled the page. SEOtto shows it when the page changes on your site. Below are four common problems, and what each one looks like in SEOtto.

Organic search traffic

last 9 weeks

Tuesday's deploy

Analytics shows it, three weeks later

A traffic line that is flat until a deploy, then declines slowly. SEOtto raises an alert in the hour of the deploy; the decline is visible in analytics about three weeks later.

Noindex tag on live pages

A noindex tag tells Google to remove a page from search results. It often reaches the live site by mistake, from a staging setup or from the WordPress setting “Discourage search engines from indexing this site”. SEOtto checks the meta robots tag and the X-Robots-Tag header on every page.

  • A critical alert after the crawl that finds it
  • What the page said before, and the day it changed
Pages
SEOtto pages report filtered to noindex: three URLs with noindex, nofollow, the previous value (not set) and the date of the change

robots.txt blocking Googlebot

One line in robots.txt, Disallow: /, stops Google from crawling your whole site. The pages still open in a browser, so nobody notices. SEOtto reads robots.txt at the start of every crawl, the way Googlebot reads it, and keeps every version.

  • A critical alert when robots.txt blocks the whole site or Googlebot
  • Also checked on every crawl: the sitemap, the redirect to https, www and non-www, and the SSL certificate
Checks
SEOtto site checks: robots.txt allows crawling fails because of Disallow: / for User-agent: *, the other site checks pass, and the robots.txt file as served

XML sitemap errors

When your sitemap returns an error or comes back empty, Google finds your new pages more slowly. Your server logs nothing, because nothing failed on its side. SEOtto loads your sitemap on every crawl and counts the URLs in it.

  • An alert when the sitemap fails to load, is empty, or loses 20% or more of its URLs
  • Every issue says what it means and how to fix it
Issues

404

URLs in the sitemap, last 8 crawls. 214 yesterday, then a 404.

Title tag, meta description, H1 and canonical

A new theme or a plugin update can change these tags on hundreds of pages at once. SEOtto saves them for every page on every crawl. It flags tags that are missing, duplicated or too long, and canonicals that point to a different page.

  • A preview of how the page may look in Google
  • Character counts for the title and the meta description

Track SEO changes on every page.

SEOtto compares every crawl with the one before. Each difference is saved with the date, the old value and the new value.

  • Old value in purple, new value in blue
  • On every page: status code, noindex, canonical, title, meta description, H1, redirects, Open Graph and structured data
  • For the whole site: robots.txt, line by line, and the sitemap
  • Change history kept for as long as the site is monitored
Changes
SEOtto changes feed: HTTP status from 200 to 404, a robots.txt diff that adds Disallow: /, and a canonical URL before and now

SEO alerts by email, Slack and webhook.

You get one message per crawl, and only when an issue opens or is fixed. It names the page, says what is wrong and what to do. The first crawl of a new site sends no alerts.

  • Email on every plan. Slack and webhooks on Pro and Agency
  • Choose the lowest severity each channel gets
  • Accept an issue you meant to have, and it stays quiet until the value changes
Email
SEOtto alert email: robots.txt blocks the entire site, and /customers returns 404, each with what to do
