Uptime and SEO for every site you ship

Freelance developers and small agencies who look after several client sites and want to know when one goes down or slips in search, before the client notices.

Each page is checked at the interval you set for it, down to every few minutes. Every check records the HTTP status and the response time, which feed the uptime figures and the charts. You can also require a text on the page, so an error page that still answers normally counts as down.

The page is rendered in a real browser as a mobile visitor sees it, then checked across ten topics. You get a score out of 100, a score per topic and a list of what to fix with the values we measured. Each page is analysed again every week by default, or daily or monthly if you prefer. Site-wide checks complete it: missing pages that answer 404, one address for the site, email authentication (SPF, DMARC) and titles shared by several pages. Each analysis is compared with the previous one, and you are alerted when a page stops being indexable or its score drops by 10 points or more.

Yes. Every page has its own status page behind a private link that you choose to share. It is not listed by search engines, and your notes and contacts never appear on it. You can also keep the status pages of a domain to yourself.

In the language you choose for each domain: English, French, German, Spanish or Italian. The status pages, the PDF reports and the alerts sent to the contacts of the domain follow it. Your own client area stays in English.

To you by email, as push notifications on your phone or computer if you turn them on, and to the contacts you add on each domain: email addresses, Discord or Slack. You get one message when a page goes down (a failure is checked again 20 seconds later, then once more a minute later, and only alerts if it still fails, so a short blip never does) and one when it is back. When several pages of a site fail together, they share one message, and a site that keeps dropping sends at most one of each every 15 minutes.

Kolteo installs like an app from your browser: "Add to Home Screen" on a phone, "Install" on a computer. Turn the push notifications on in your profile and the alerts of your sites reach that device, in addition to the emails. On an iPhone, add Kolteo to the home screen first.

Yes, if the site uses Matomo or Google Analytics. Connect it on the domain with access that can only read: the domain page shows the visits, sources, top pages and countries of the last 30 days, and the monthly report the visits of the month. Kolteo only reads totals, never the data of a visitor.

Yes. Every domain is checked once a day. You are warned 14, 7 and 1 day before its HTTPS certificate expires, right away if it becomes invalid, and 30 and 7 days before the domain name expires. A few extensions, such as .io and .eu, do not publish their expiry date: Kolteo then says so instead of guessing.

Only what you choose. Each page has a status page you can share, and contacts you tick get a monthly PDF report on the 1st, with your logo: uptime, incidents, SEO with what was fixed during the month, the visits of the month if the site uses Matomo or Google Analytics, and renewal dates. By email it comes attached, on Discord and Slack as a summary with a download link.

On servers in Frankfurt, in the European Union. Kolteo has no advertising or tracking cookies and never sells data. The privacy policy details what is kept and for how long.

Up to three domains per account and ten pages per domain. Pausing a domain stops its checks without losing its history.

Yes. Kolteo is in beta: every feature is free, with three domains and ten pages per domain, and no credit card is asked. We first want to see how freelancers use it, and your feedback shapes what comes next.
