Meta tags are not the only solution for organic search engine optimization. They are simply one piece of the overall search engine optimization process. The title tag and the meta description tag are what searchers see in the search engine results pages (SERPS). So optimize these tags and include a marketing message to help users click on your website. Here are some basic Meta Tag rules with 2008 standards applied.
TITLE TAG RULES (HTML Tag) The Title Tag is the most important part of a Web page to optimize. It appears at the top (title bar) area of the Web browser and as the first line in the search engine results page. On most search results pages the title tag is used as the main link to the site in the listing. Most importantly the search engines use them to determine the theme of the website. Here's how to use the TITLE tag most effectively:
Place the TITLE tag within the tag
Should contain the most important keyword that appears on the Web page
Limit to 40-70 characters including spaces between
Place the most relevant keyword phrase at the beginning of the text
Don't blatantly repeat the keyword.
Don't use stop words such as "the", "a", "as", "of"
Should read well and contain a marketing message
DESCRIPTION TAG GUIDELINES ( Meta Tag) The Meta Description Tag is an important part of a Web page to optimize and appears as the second line in the search engine results pages. It basically provides a brief description to the visitor about your webpage and sets their expectations. Place your Meta Description Tag directly below the TITLE tag. The difficult part is optimizing this tag for both the spiders and your site visitors. Here are some tips to remember when optimizing your Meta Description tag:
Limit the number of characters to 180
Blend keywords that appear on the Web page with a strong marketing message and call to action
Limit the use of stop words and don't repeat words
Keep keywords unique to the Web page
Write in complete sentences and keep important keywords at the beginning of the description
Place tag within the section of the HTML code
H TAG RULES (HTML Tag) H tags are built-in function of HTML that shows the text within this tag as a header. They are assigned a value (1 being the most important) and repeated on the same page. The most common use of the H tag is the title or top line of text that appears on the web page, the header.
Use H1 tags for the header or most important text of the page
Use CSS (Cascading Style Sheets) to control the color and size of the tag
H tags give some extra importance to the words within it
ALT TAG RULES (HTML Tag) You will most likely want to include some images on your site. The Alt text can usually be seen by hovering over a picture with the cursor in a browser. A helpful way to boost your search engine ranking is to include the ALT attribute, which means alternative text. This tag is read by search engines and they also contribute to the on-page optimization.
