There are two ways to add your site to Search Engines.
1 - You can submit your site to the Search Engine 2 - Meta tags embedded in your script
1- Most search engines allow you to submit your site for free to be approved and added to their search engines. To do this you go to their main page and find about the site i.e. Google. At the bottom of their web page is About Google. When you click on this it will redirect you to "About Google" help area and under the Heading of "For Site Owners" there is a section where you can submit your site. Simple add your url and after approximately 2 weeks your site will appear in their listings if approved.
2 - Meta Tags On the 110mb panel under Webmaster Tools in the HTML section there is a "Meta Tag Extractor" and "Meta Tag Generator".
Meta Tag Extractor - Simply put your url into this and it will extract the tags you need. In some cases it will not find anything if you do not have enough words repeating on your site.
Meta Tag Generator - Place your information that you would to appear when a search is done. This will generate the script for your meta tag. Simply paste this into the body of your web page scripting and make sure you have closed your head before this. It is best to do this for all your web pages as each one displays a different topic that people might search for.
