I'm building a new real estate website and need some pointers on navigation placement. This will be a large website that serves several counties in my area, so there will be a lot of pages to try to rank. The code and structure of the site is built in such a way that it has the capability to rank well with proper content and SEO, so my question is this.
The navigation on this website comes with a 7 tab top menu and a full right column navigation menu that will carry from page to page. My initial thought was to link all the pages I want to rank from the top drop down menu for visibility purposes, but on the other hand, it seems if I do this that the search engines will have to run through all those pages linked to the top nav before getting to the contents of any given page, thus watering down the keywords and content for each page I'm trying to rank.
For this reason, it seems a better SEO plan to keep the top nav pretty light on page links and instead run the other pages I want to rank down the right column nav, which would then be read by the search engines "after" reading the page content for any given page I'm trying to rank. Can anyone tell me if this is a good SEO plan or not? My concern in putting all the pages I'd like to rank in the right column nav is that it will make those pages more difficult to rank because they are now the very last thing on every page that the search engines will read. If I put them in the top drop down nav, they would be the first thing the search engines read.
