Question on SEO for a Local Services Business

Let me preface this by saying I am very new to SEO, but it looks like that is what this group is for!

I am starting a small, residential cleaning business and trying to work SEO into my strategy.

After doing keyword research on my competitors, the most highly searched words that generate the most traffic for some of the bigger local players are keywords like:

- "cleaning services [my location]"

- "maid services [my location]"

- "cleaning company [my location]"

​

All of the top SERP's for these keywords are not blogs or in-depth content, but home pages/service pages for different cleaning businesses in the local area. When I think SEO, I normally think how to tutorials, comparisons etc. but it seems like in this niche, people just want to see your offering on your home page and book a clean and don't need to read up on the space first and learn about the different supplies you need to deep clean a house, for instance.

In this context, should I simply focus my effort on optimizing my home pages/service pages or is there something I am missing and should I also be looking in to more blog posts?
