1. File size - Always be reminded that web pages of a particular website should be light in terms of file size. It would be hard for search engine spiders to categorize an overly heavy web page filled with HTML "junk text".

2. Content - An extremely readable content is an important key to remember in order to create a rich content code that will help in optimizing the content of any web page. Always maintain a good content to code ratio. By doing this you will also prevent an overly heavy web page; ensuring a file size that is ideal for search engine spiders to categorize the site.

Cascading Style Sheet (CSS) is an important tool to use in order to benefit Search Engine Optimization (SEO). CSS is used to refine a certain page in order to achieve a page that is spider friendly. Spider friendly page means a page that is created with maximized keywords making it easier for "web crawlers" to recognize and categorize them properly.

Websites designed with the use of CSS are ranked higher than table-based websites because of the following reasons:

1. CSS codes are more accessible because CSS codes are cleaner making them easily readable by search engine spiders.

2. CSS designed web pages load faster than table-based web pages because the code weight is low and lighter than table-based web pages.

Thank you for sharing this information

CSS makes your website SEO friendly because search engines spiders are actually very lethargic. They do not go through the bundles of HTML codes to get to the indexed codes. Font tags and tables make the HTML code very cumbersome; thus, reduce the accuracy of the results. If you use external CSS files to design and determine the design attributes; the HTML code will be clean and it will result to better search engine rankings.

thx you !!
