Google has a "memory" and lets assume your client keeps searching their own site...for whatever reason. Over time, after they've searched a term, and clicked the site... Google will weight that higher for them only.

I'm not positive this is your clients case - but could be it. Another issue that could be impacting it is the local search results. Your clients local returns could be impacting placement versus your default location results.

Hope that helps you figure it out.

Ah I found the problem. It was my Advanced search that I had all languages and not english so it gave different rankings.

Thanks for your time buys.

Sorry, no top 100 rankings for those 2 keywords, so much for keyword domains.

BUT

Checking 100 other crib terms turned up some matches (only getting ranked in Google, not yet Yahoo/Bing)
