For Escrow payment release verification and for 45 day guarantee verification, we use the Google Rank Checker provided by KeywordTools.org at https://www.keyword-tools.org/en/google-ranking-live-check/
You would enter one of your guaranteed keywords into the "Your keyword" blank and then you would paste your Yelp page URL into the "example.com" URL blank.
Note: Per our contract, you must turn off personalization to check the ranking. This is due to cached results that can take a little longer to disappear for you.
After clicking the "Research" button and waiting for it to load, you will be presented with that specific ranking for the URL using that keyword.
If the ranking shows as #-/- or anything over #50, that is a success per the contract.
If it's time to verify your guaranteed keywords (due to YelpDelete.com notifying you we were successful for a specific guaranteed keyword) and Keyword-Tools.org is not working for more than 48 hours, the keyword position will be verified using https://smallseotools.com/keyword-position/
