Meta is the Greek word for "over", and the "meta-tags" were initially designed to carry all sort of meta-information, meaning "information-about". Using meta-tags for specifying keywords or a description for a webpage is not an HTML standard convention, but it is a widely accepted use of the meta-tags.

You should add keywords in Meta tag which define your website. Most search engines still give high importance to Meta tag and use it as a determining factor for ranking a website. Some search engines give less importance to Meta tags but when you consider SEO, it's very important that you consider each small and big factor.

Back in the early days of the web, the search engines did not rely on links to determine how relevant a website is for a particular keyword. Instead they primarily looked at on-page factors to determine rankings. To get rankings and traffic, it was a competition of who could get their target keywords into all the right places of their website. One key spot to put their target phrases was the keywords meta tag.

First and foremost, your description must be relevant to your website. It should convey in a few words what your target audience should expect to get out of using your website. Your description should directly relate to both the title and the body content of your website. With that being said, every page on your website may not necessarily have the same description.

By inserting as many targeted keywords in the Keyword Meta-tag, they figured that they could influence the rankings of said websites by confusing the rather simple search engine algorithms of the time into incorrectly identifying their websites as qualified for those keywords; even though such keywords never appeared anywhere in the main body of text.

According to websearchworkshop.co.uk, SEO is the term used to describe the marketing technique of preparing a website to enhance its chances of being ranked in the top results of a search engine once a relevant search is undertaken. A number of factors are important when optimizing a website, including the content and structure of the website's copy and page layout, the HTML meta-tags and the submission process.

If your Title Tag reads "Online Job Directory" and your web page is about "online gambling" you are not only misleading your visitors, but you will most likely incur a penalty by the major search engines. The penalties imposed by search engines can be anything from a lower search engine results ranking to an all out ban of your entire site/domain.

Creating good content is essential. Each page should have useful content and include your important keywords. Don't try to stuff all of your important keywords onto a single page. Create pages around a theme, a small collection of keyword phrases. For instance, target 1-3 keyword phrases per page. Write a title that incorporates those keyword phrases.
