With Big G, making it clear that 2009 will see changes where SEO is concerned and would include more SEM and Ad bases Optimizations, it only makes sense to list down some common practices and do’s and don’ts of SEO.
This is just a basic list type article on the do’s and dont’s of SEOs.
Do #1 The <title> tag in your HTML code is a must. This tag fits between the <head> and </head> tags. The <title> tag should contain the title of the page, with the title containing the keywords to be used for the content. It is preferable to have these keywords in the first part of the title itself.
Do #2 Page URL should contain the keywords selected. If content is served up dynamically it helps to have the pages being name as static .html files. For e.g. http://www.yoursite.com/keyword-title.html is a must do. Use of “-“ helps differentiate words for search engines.
Do #3 Keyword densities should be taken care of. The primary keyword used should have a keyword density of approximate 3-5% and secondary keywords used should have a density of approximately 2-3%.
Do #4 Anchor texts or text links should contain keywords, wherever possible. If you are getting backlinks or one way links from other websites make sure that these use keywords in the link backs.
Do #5 Use of heading tags is highly recommended. Use <h1>… <h6> tags wherever you can and wherever you can use them to highlight keywords, titles, etc.
Do #6 Use keywords in the beginning of the document content. This helps search engines index your keywords faster.
