When we optimize a web page, we optimize for two audiences: search engine spiders and readers. Each page should target both audiences.
Optimizing web pages for the major search engines is a very demanding skill. We need to pay special attention not only to text that appeals to search engine spiders, we also need to understand the human side of optimizing that text. Your conversion rates will depend on the ability to target the emotional needs of the reader, as well as the logical needs of the spiders.
It's imperative to think of the search engine optimization process as a long-term investment for your site. That's why it's so important to place the optimization work into the hands of an experienced firm like WebIt.
