A lot of companies have been asking me what are the primary needs for building a strong SEO foundation.
The honest trust is you need diversity and quality. The higher end inbound links will support the majority of your SERP ranking ability. But, the lower quality, possibly higher quantity backlinks can be great for targeting keyword anchor texts.
Backlinks? From where you might ask.
Every place you can. Don't spam one style of backlinks, especially if its automated and of low quality. Try to build a lot of contextual links, inbound links that are supported with strong amounts of unique content and imagery. This will get indexed the quickest and benefit you as they grow and gain higher page rank from Google, Yahoo, and Bing over time.
Since Google's Panda update has changed the search engine environment for all keyword terms, you've got to focus on writing really high quality content. Keep topics focused and giving useful information to your visitors, this will help lower your bounce rate and get you to an authority status earlier. Some SEO's will say that authority websites need 1,000+ pages to really get the big traffic numbers, so I say, start writing!
