What SearchScore is, and who it is for
Three scores, one audit. SearchScore scores a site on GEO, SEO and CRO from 300+ signals, free and instantly; its free audit reads your site and does not query the AI engines.[1]
A weekly tracker. The paid Tracker checks AI citations weekly across ChatGPT, Claude, Gemini, Perplexity, Grok and DeepSeek, with sentiment, position and competitor monitoring, and grades each plan's measurement against IAB quality standards.[1]
Consulting on top. A London consultancy behind it will ship the fixes, with one-off engagements carrying a 30-day score-improvement guarantee.[1]
Proofsource is an AI intelligence platform that shows which buyer questions name your brand in ChatGPT, Perplexity, Claude and Google AI Overviews, who gets named instead, and exactly what to fix.

Where each shines
Both tools are built well for different teams. Each point is a strength, read from that vendor's own pages.
Where SearchScore shines
- Six engines, including Grok and DeepSeek. Every Tracker plan covers six AI engines.[1]
- SEO and conversion in the same score set. GEO, SEO and CRO scores with fix lists, plus a free audit that needs no account.[1]
- Open about measurement grade. Each plan states whether its question count reaches IAB directional or decision-grade, which helps a buyer judge how much to trust the number.[1]
Where Proofsource shines
- Daily, not weekly. Proofsource re-reads every day on Custom. SearchScore scans weekly on every tier.
- Google AI Overviews on the panel. Proofsource reads ChatGPT, Perplexity, Claude and Google AI Overviews. SearchScore's Tracker engines are ChatGPT, Claude, Gemini, Perplexity, Grok and DeepSeek.
- No card for the trial. 200 answers. 25 Prompts/Question. Top AI engines. 2 days. Free. No card, no sales call. SearchScore's Tracker trial asks for a card. Each gap also comes with a drafted fix held for your approval.
Proofsource or SearchScore: the fair verdict
SearchScore is a strong choice for a team that wants weekly AI citation tracking on six engines alongside SEO and conversion scores, and values a published measurement grade.
Proofsource suits a team that needs daily reads on Custom, Google AI Overviews included, an interval on every share, and a drafted fix for each gap, starting from a free trial with no card.

Already using SearchScore?
You do not have to choose on day one. Here is how teams run Proofsource beside SearchScore and decide on their own data.
Keep SearchScore running
Nothing about trying Proofsource needs you to stop SearchScore. Your history and reports there stay where they are.
Bring your questions across
Export or copy the prompts you track in SearchScore and add them as buyer questions in Proofsource, so both tools ask the same things.
Run both side by side
Read the two for the same days on your own domain. Where the numbers differ, Proofsource shows the answers and the pages each engine cited, so you can see why.
Keep what serves your team
Many teams keep one tool for reporting and another for fixes. Pick on your own evidence, not on a comparison page.
Proofsource or SearchScore: what buyers ask
What AI visibility tools give a normalized score so I can compare my brand's AI presence to the market leader?
Tools that ask every brand the same questions, more than once, and report each share with its uncertainty. SearchScore asks each question twice and grades its plans by question count. Proofsource samples each question repeatedly and puts a 95% Wilson interval on every share, so you can see whether the gap to the leader is real.
How often does SearchScore scan?
Weekly on every Tracker tier, with on-demand hourly rescans on Scale. Proofsource re-reads every day on Custom.
Does SearchScore's free audit check the AI engines?
No. SearchScore says its free audit reads your site's own signals and does not query the AI engines; the paid Tracker does. Proofsource's free trial asks the engines your buyer questions directly.
How much does SearchScore cost compared with Proofsource?
The Tracker starts at £49 a month for 10 questions on six engines. Proofsource starts free, then Custom from $64 per brand per month (final price discussed on demo call).
