Fathom, Thanks for the thorough response.
Ok, now I think I have an idea of the basics. Let me pose a more specific question. I am a web design company and I have offices in Portland, Oregon, Washington DC, Atlanta, New York and Phoenix. I want to market our firm as if we are local in all 5 locations, but am afraid I will dilute my site by trying to market to each of these locales because that means I have 5 times the amount of keywords to deal with (portland web design, portland website design then atlanta web design and atlanta website design, etc).
When I first started this, I purchased 5 domains, atlantawebsitedesign.info, washingtonwebsitedesign, etc (I had read that having keywords in the URL mattered, but I have read otherwise since then). I built 5 sites that were similar in appearance but with different text catering to the local market. My goal was to appear in the Google results for each of the keyword phrases like "New york web design", "Atlanta Web Design", etc. I was not going to interlink the sites (re: I wasn't trying to do shady linking scheme to build
PR), but just couldn't figure out how to market locally without having specific sites targeted to each locale.
After reading a lot of posts I am starting to "rethink" my strategy. Perhaps it is better to have one site, my main gravitatedesign site with subdirectories like gravitatedesign/portland-web-design.htm, gravitatedesign/washingtondc-web-design, etc. If I went with this approach, I would have the following questions:
1. Should I use all of my locales in the title tag of my main index.htm page. Something like "Web design company with offices in Portland, New York, Washington, and Atlanta." I would provide a link from this page that would link to individual pages like portland-web-design.htm. My concern here is it seems that the title tag on the index page is wordy and I think I have read that the shorter more specific the title tag is the more weight to the targeted keyword. Which leads me to my next idea..
2. On my index.htm use a more general title tag like "Web Design, Print Design..serving the U.S." Then I would have this page link to my 4 or 5 local pages where they would be keyword rich in the body and the title tag.
3. I have my site listed in several web design directories. Regardless of which direction I take above, should I have all of these directories point to my main index.htm page, or should I have for instance my directory about Portland web designers point to my "portland-web-design.htm" page, and my Atlanta directory point to my "atlanta-web..." At first I thought it was more important to have everyone link through to my index page, but maybe that is not the best way.
That is probably a good starting point. I don't want to ask so many questions as to scare anyone away.
Happy New Year!
