Something I come across alot. People want to set up a brand new micro site, and think it will just genereate traffic. This isnt the case anymore, your site will conflict with your main site. Read on for 2 min to see why.
The question of whether or not to utilize microsites is an interesting topic of discussion for SEO. On the one hand, microsites allow organizations to segment information and focus a site clearly on one topic. For instance, it’s not uncommon for an organization or association that hosts conferences to have a separate conference-focused website for registration and information aside from the main organization website (as Search Engine Land does with the SMX conference site). Or, if you own several car dealerships, you may want or need to have a separate website for each dealership location.
