With their most recent design, it’s nigh impossible to even identify an ad from a search result.
Start and maintain a $100/month adwords account, and magically, one's domain gets free SEO (moving up in ancillary search results) --> every S.E.O advice on the internet openly states this.
This is what Google used to be like. They have fallen a long way from this high ground.
With most results above the fold being ads these days, this is a pretty tone deaf message to put out there.
