Com lets you take MasterCard, Visa, American Express, and Discover. The problem that many of us have run into is each of the six major search engines use slightly different algorithms to determine placement. A web page that places well in one search engine may be relegated to obscurity in the others. I believe that the answer is no. Good placement with multiple keywords can be achieved through the use of portal pages.
Portal pages are pages that are designed to place well in the search engine for a keyword or phrase.
They can also be optimized for one particular search engine. These pages then provide links into the substance of your web site. Now before someone accuses me of spamming the search engines, let me make it clear that I am still talking about pages of value and substance. The pages I am advocating are merely optimized to give the page its best chance at good placement. It is essentially having a customized entry page for each search engine and keyword or phrase.
