Before Google penalized eBay’s search standing, eBay authored a study claiming Google Search ads are useless
Two things: it appears that Google Ads provide little of value; and, it you point that out, Google appears to do the equivalent of ‘burning down the house’ in order require the use of ads, even if they provide no value. It changes its ranking algorithm to remove your links from the top searches.
Looks like buying Google Ads is more a form of tribute than a benefit. Google gets paid in order to keep an online company’s search rankings high. A zero-sum approach rather than a win-win.
So besides grabbing all our data to sell without recompense, Google requires tribute from online companies. More and more they are degrading the usefulness of their main purpose to exist – search. I routinely now get highly ranked pages that do not have my search terms anywhere on the page. Totally useless.
Perhaps time to check out Duck, Duck, Go.
