Algoroo vs GSC Guardian (2026): which should you pick?

Pick Algoroo if

• Fits if your rankings just dropped and you want to see whether all of Google moved that day
• Works for sites ranking in Australia, with google.com.au beside google.com

Look elsewhere if

• Not for you if you want your own rankings tracked, as it doesn't do that at all
• Skip it if you need a market other than google.com or google.com.au
• Too light for real analysis, since the keyword set behind the score isn't published
• Watch out: the Weekly Winners and Losers sections have their data switched off and were empty when read
• Watch out: it's a web page only, with no app, API or integrations

Pick GSC Guardian if

• Fits if you explain traffic drops in Search Console against Google's updates
• Works for agencies keeping a dated record of changes on client sites

Look elsewhere if

• Skip it if you don't have a verified Search Console property, as it works nowhere else
• Too light for page checks, since it adds notes to graphs and checks nothing on a page
• Watch out: project-tool integrations, automatic rules and a multi-account dashboard wait on a Pro version with no date or price
• Not for you if you're not on Chrome, and the developer hasn't identified itself as a trader, so EU consumer rights don't apply

Algoroo

• It measures movement across its own keyword set; it does not track your site's keywords or positions.
• Only google.com and google.com.au are covered, on desktop and mobile.
• The keyword set is not published; the site describes it only as thousands of carefully selected keywords.
• The page has Weekly Winners and Losers headings, but their data calls are switched off and both lists were empty when read.

GSC Guardian

• It works only inside Google Search Console, so it needs a verified Search Console property.
• It is listed for Chrome only, in English (US) on the store, though the listing names nine interface languages.
• Integrations with project tools, automated annotation rules and a multi-account dashboard are listed as coming in a Pro version, with no date or price.
• The Chrome Web Store notes the developer has not identified itself as a trader, so EU consumer rights do not apply.

Algoroo

Daily roo score

Each day's ranking movement across the watched keywords, up and down, is summed into one figure; a high roo means unusually volatile results.

Color-coded timeline

Ordinary days stay green, while days with unusual movement turn orange or red, so a likely algorithm change stands out on the chart.

Google update notes

When Google discloses an algorithm update, Algoroo adds it as an annotation on the matching day of the chart.

Two markets, two devices

Switch the chart between google.com and google.com.au, and between desktop and mobile results.

Today's summary

A short note compares today's score with yesterday's and counts the days since the last orange or red spike.

History back to 2017

The data behind the google.com desktop chart starts in July 2017, so a current spike can be set against earlier updates.
