Zivaro Website Check.

If you found ZivaroSiteCheck in your server logs, this page explains it. Someone typed your website address into a free check that reads a site the way a customer's phone does.

Last updated: 5 November 2026

What it is

Zivaro Website Check, at check.zivaro.co.za, is a free tool for South African small business owners. It scores a website on what helps a customer pick up the phone: speed on mobile data, real photos, reviews and prices, tap to call and WhatsApp, how current the site looks, and whether links and buttons work.

Anyone can type in any public website address, so a visit does not mean the site's owner asked for it. Zivaro also runs the same check on sites it is researching.

What it reads

  • Up to 10 public pages, loaded one at a time with a pause between them, in a phone sized browser.
  • Your robots.txt and sitemap.xml.
  • A plain request to each internal link it finds (up to 40), to see whether it loads.
  • Your home page address is also sent to Google PageSpeed Insights, which runs its own test.

What it never does

  • It never fills in or submits a form, logs in, or clicks through a checkout.
  • It never requests admin or hidden paths such as /wp-admin or .env, and runs no security or vulnerability tests.
  • It never visits a page your robots.txt disallows for it.

How it identifies itself

The browser sends a normal mobile Chrome User-Agent with this added at the end:

ZivaroSiteCheck/0.1 (+https://zivaro.co.za/website-check)

Plain requests (robots.txt, sitemap, link checks) send:

Mozilla/5.0 (compatible; ZivaroSiteCheck/0.1; +https://zivaro.co.za/website-check)

How to block it

Add this to your robots.txt and the check will stop before it loads any page:

User-agent: ZivaroSiteCheck
Disallow: /

Or email me at hello [at] zivaro [dot] co [dot] za with your domain and I will exclude it.

What is kept

The address that was checked, the result, and a one-way hash of the IP address that asked for the check. Full results are deleted after 30 days. Nothing is collected from your visitors.

Who runs it

Kent Weyers, trading as Zivaro, a one-person web studio in Durbanville, Cape Town. The privacy policy covers the rest of this site, and hello [at] zivaro [dot] co [dot] za reaches me with questions or complaints.
