Haven inserted the keywords, you should then get others linking to you to use a few of the keywords in your meta tags to link to you. You ranking should shoot up if you can get some decent sites linking to you with those keywords.
The Meta tag in html is not a required tag when you're creating your web pages; many pages don't use the tag at all, and I must confess that I've not used it on my home page, although I put it into this page by way of demonstration. To put it briefly, the meta tag is used by search engines to allow them to more accurately list your site in their indexes. Sometimes.
If you simply produce your home page and register the URL with a search engine, or a number of search engines, their spider programmes will (eventually) toddle along to your site to index it. Now, each of the search engines does this slightly differently. Altavista for example will grab everything in your document and index it, but will only show the first 250 characters in its description. Consequently, if your site included say, 'Thanks to:....' right at the beginning, this is what Altavista would show in its description, and it wouldn't give the viewer any idea of what your site actually covered. Of course, not all search engines work this way; I'd suggest you ferret around a little bit to see exactly how the popular engines work, and certainly the major two or three such as Altavista, Lycos, Yahoo, Infoseek and Excite. It therefore makes sense to ensure that your opening paragraph is carefully written to ensure it accurately reflects what your site covers.
However, you may be able to exert a certain amount of control over how your site is indexed by the use of the meta tag.
Meta keyword tag is supposed to be summary list of vital words on page. They were both proposed to make using web easier. Sadly, webmasters over years have abused meta tags so much that search engine creators had to de-emphasize their importance in their algorithms.
Meta tag is a special HTML tag that is used to store information about a Web page but is not displayed in a Web browser. For example, meta tags provide information such as what program was used to create the page, a description of the page, and keywords that are relevant to the page. Many search engines use the information stored in meta tags when they index Web pages.
You can run your site url through a meta tags analyzer tool. That will indicate if your title, description and keywords are being used correctly. For many sites, they are usually too long or too short. It is about getting a nice balance and striking a happy medium.
