Optimizing Your Site for Both Google and Yahoo!
I learned a lot from this short article! It clarified the differences between advertising with Google and Yahoo! According to this article, because I built my Web Site with the proper meta tags, URL, and keyword density, I should start my advertising with Yahoo first! And then after I've got inbound links to my site, then advertise on Google.
“Yahoo places emphasis on website URLs, meta tags, and keyword density. These factors can be analyzed on any website with a limited amount of effort, allowing Yahoo to quickly and easily rank websites properly”. Quote from article.
