The tags are designed to assist search engines in sorting and categorizing web sites. When writing META tags for your HTML documents, create several tags and incorporate them into each page of your web site. Then resubmit each page of your site to all the search engines and directories. Make sure you use keywords in both the descriptive paragraph and in the keyword listing. Do not overdo using keywords, though.
Some search engines use the tags to index sites, but some have grown suspect of their use.
Your site could be dropped if you lace your document with keywords. They throw a site together and register with search engines without giving any thought to what they expect from their site and how their businesses may change in the coming months. Plan carefully every detail of your site before you register it with search engines and directories. Keep in mind your ultimate goal for the site and how your business may change. When determining the contact person for your site, think long-term.
