If you go to Google.com and type “hamburgers,” “shoes,” “candy,” “grills,” “beer,” and hundreds of other terms of ambiguous local intent, Google will almost always show you local results on a map that’s tied to your IP address.

But type in “seo,” “seo company,” “web design company” and several terms related to these two types of businesses — heck, go ahead and specifically add in a city name like “seattle” or “houston” or wherever, and even include the state abbreviation like “wa” or “tx” — and Google will almost never show you local results on a map.

I’ve noticed this for SEO queries eg. SEO expert as well.

Seems that the local results are only limited to the top 3 or don’t show up at all.
I don’t see this to be a big issue since I believe the huge majority of small businesses that require SEO and web optimization services don’t search for such services online so much. I believe that the reason for this is that they don’t know that their website’s visibility can be enhanced by SEO.
