SEO Rank Tracker

Rank tracker (SEO Intelligence add-on). Measures a domain's LIVE Google position for each keyword, stores every measurement, and reports the change since the previous run — so the second call onwards you get movement, not just a number. With `auto` left on, the keywords keep being re-measured once a day and the history builds by itself. Returns per keyword: current position, previous position, change, the ranking URL, and who holds the top spot. `position: null` with `measured: true` means it was checked and is NOT in the scanned depth — that is a real answer, not missing data. `depth` is how deep to look (20 default, up to 100); deeper scans cost proportionally more because the provider bills per result. `device`: desktop or mobile — they rank differently. Reading the stored history back is FREE through seo_rank_history; it does not re-measure. Costs SEO add-on credits per keyword; top up → Add-ons.
