Cumulative effect

[mikescotty]

<a name="_GoBack"></a>I have a real estate client who creates individual property sites (mini-sites), each with their own URL (123MainStreet.com), each linking to 2 or 3 diverse pages on the main broker site (main site). There are a couple thousand on these pages at any one time, feeding into a large broker site.

The SEO effect of these mini-sites is that there are many incoming links to the main site from various URLs, however, the mini-sites have little SEO relevance, given that there are few, if any inbound links to the mini-sites themselves, and the mini-sites only exist for the market life of a property.

My question is: Does it make more SEO sense to create a series of pages (externalsite.com/123mainstreet) on a single site that already has good traction and relevance?  The inbound links to the main site will have more relevance, but they will all be coming from the same domain (or subdomain).  And although the links will all be coming from the same external site, the inbound links will be from a variety of pages on external site to a variety of pages on the main site.

Any insight would be appreciated.

YES!

This is what I would do.  The more powerful site should toss them higher into the SERPs right away... and they will enrich the site with fresh content for search engines ... lots easier to manage and less costly.
