This isn’t just about keywords by market which is endlessly fascinating, but it also says a lot about their markets…. the sheer volume of terms in SF compared to, say, Portland is pretty intriguing.

750+ pages of terms for SF, 521 for LA, 443 for Chicago, only 59 for Sacramento, 63 for Portland, etc.  Enter your city and see if it is at all worthwhile or interesting for you.

Cheers… just thought I would share.

Also….

I apologize for posting the below (I had published the keywords, but didn’t feel comfortable with them, now I just list the #), as it is the nefarious naughty words of net searches… but I doubt this will be up for long, due to searches like this tarnishing yelp’s equity with user base searches like #35, #47, and #60 among other less illegal or salacious terms on the SF search term board (like #99).  Ouch, yelp.  Ouch.  If these pages are removed, I will post the terms.  Frankly, they are sort of disturbing. =/  Can any SEO people suggest what these are?  I cannot believe they are organic searches?
