More web pages of useful & relavent content = more relavent search engine traffic
Here’s why:
Adding pages to your site is like putting out extra nets to catch relavent prospects.
Search engines see bigger web sites as more prestigious and reliable and useful.
The more content you have, the more reasons you give other sites, particularly bloggers, to link to your site spontaneously, without being asked.
Value to prospects
Organic search engine results tend to be seen as non-biased, and they therefore are able to provide visitors that are more valuable. The overall conversion rate, or the rate at which searchers take a desired action on a site, is 17 percent higher for unpaid search results than the rate for paid (4.2% vs. 3.6%) . Trends also have shown that more of the sales that result from search engines originated in organic search listings
Relevant and usefulness
Prospects also have rated organic search engine results as more relevant than paid results. On Google, 72.3 percent felt that organic results were more relevant, while only 27.7 percent rated paid results as more relevant. Yahoo offered similar results, with 60.8 calling organic results relevant compared to only 39.2 percent for paid .
