Web Design & Search Engine Optimization

How Can Web Design Affect Search Engine Optimization & Corresponding Rankings?

Directory editors will actually review your site and be critical of issues that you might not be.Search engine spiders can't see what you and I see so they must rely on the specific algorithms set for them. Some of these algorithms are going to depend on design issues in your web site.When directories or spiders become confused or slowed down because of design issues, your page becomes less relevant.

Web Design Considerations When Preparing For Search Engine Optimization...

Use Cascading Style SheetsBy using CSS, you are specifying certain factors such as font, color, paragraph style, etc. all in one place of your page instead of throughout your page. By doing this, you will make your content appear to be more prominent throughout your pages and will make it easier and quicker for a search engine spider to get through your pages. Keep in mind that all CSS is not compatible with the Netscape browser.

When Preparing For High Search Engine Rankings, NEVER:Submit an unfinished site. Submit a site that includes words such as "Under Construction". Include text on your home page that says something like "report broken links here". Include a phrase such as this on your contact page. Never on your home page. Include illegal content within your site. Use hidden text / links, tiny text / links, same color text / links as the background - this is considered spam and you can be banned from major engines and / or directories if you do this. Use clear or transparent images.

Following the above tips will give your site one more added boost to increasing the accessibility of your pages for better indexing and ranking potential.
