@Phil Rozek 1.) True enough: lots of law firms do have tonnes (clunky Canadian spelling) of links. A response in two parts:
a.) Follow those three links. You'll see that they don't take you to the home page but rather, a deeper page, with some textbook optimization for the keyword "car accident lawyer". That exact phrase appears in the page title, h1 and an h2 heading. It's also in 2 of the 3 URLs. (The third uses "/accident-attorney/car-accidents/".) Note that the URLs you see in the SERPs aren't always what you get. Bottom line: those pages were created to be found for that specific search.
b.) The anchor text of many of the backlinks is optimized for "car accident lawyer". In fact, one site has a backlink from the domain campuspress.yale.edu using the anchor text "hire a car accident lawyer"! (Impressive!) And in cases where the anchor text is just the URL, well, that too is optimized for the keyword "car accident lawyer".
So, between the page content and the anchor text of the backlinks pointing to those pages, Google is obviously pretty confident that those pages are relevant for the search "car accident lawyer". (I suppose these days it's relevant page + site E.A.T.)
2.) We all know the 3-pack/local finder is different from the organic rankings. And I'm sure we've all seen a 3-pack where one of the listed businesses didn't have a website. No website means no backlinks, which I read as an important (but still confusing) clue about how the 3-pack is determined. Or, at least it shows you that you can get in the 3-pack with no backlinks whatsoever.
Getting to the top of the organic rankings, however, appears to be more influenced by backlinks. There's a good reason I mentioned the chain "Massage Addict" previously. I have a client whose massage therapy clinic is at the top of the 3-pack (for the keyword "massage" and for a search done in the same postal code as the clinic) but is second in organic to "Massage Addict".
My client has about 40 good backlinks. Massage Addict has about 12k. (No comment on their "quality".) And Massage Addict dominates organic results around Ontario, even in cities where they don't have a location.
I'd be happy to have
@JoyHawkins weigh in. In another thread about backlinks Joy commented that Sterling Sky was able to get good rankings for clients without doing any (or much?) backlink building. My question: 3-pack/local finder rankings only? Or, also getting good organic listings for lawyers without tonnes of backlinks?
Ooof... that post is way too long...
