What business categories are using Search Enging marketing the most?

Question

You see a lot of realtors buying AdSense ads... but who else is using Search Engine Marketing (SEM)? Clearly there's a lot of trollers, using link pages to grab clicks, but aside from them, what other business segments are using SEM?

- Automobile dealers?
- Big Consumer Products companies?
- Who?

Answer 1

Real estate is one of the fastest growing markets in SEO/SEM lately, but there is quite a bit of activity in travel/tourism, pharma, casinos, etc.

Hope this helps!
