SEO web design is a skill that can be learned and it comes with experience after working on different SEO projects. On-site optimization is as much important as the link building.
Getting a good position on Google or any of the other search engines is not as difficult task, but there are certain rules to follow. If you follow this properly the result should be in your favour.
So, there are some point to consider when you designing your website or web pages.
(1) Almost everybody knows about Meta Tag and many people claim that “META TAG” is not used by search engine. But in my view its used by search engines. If you 'Google' Article Services you will finds my website right at the top in the #1 position for that keyword. Check the description that Google provides right under the title: that is exactly as it is in the 'Description' tag that I have on the site. So don't let anybody tell you that Google doesn't use the Description tag, because they do. So do Ask and MSN (now Live Search), and Yahoo also uses it, but not the whole thing exactly as written.
(2) META Keyword Tag: Google isn't interested in your keyword but it is interested in relevancy with your keywords, page text and ALT tag. Google will not entertain any duplicity in keywords. They have the LSI algorithm now that will determine the meaning of your page from the character strings it contains. The algorithm is programmed to calculate a relevance factor from the vocabulary you use in relation to the rest of the vocabulary on the page.
(3) The H (Header) tag: H1 is the most important. The heading for each main section in your page should be contained within H1 tags, and many pages have only the one set of such tags. Subheadings, containing secondary keywords, should be contained within H2 tags.
(4) The ALT attribute. Use 'Alt = ' within the Img tags of your images and graphics. This lets the search engines know what the graphic is about: search engines do not read graphics, and the Alt attribute offers you the chance to use your graphics meaningfully with respect to SEO web design.
5) Your text formatting can be used to emphasize to search engines what the important text on your page is. Thus, if you use bold text, underscoring or italics, they indicate the important words and phrases. Thus, use the STRONG and U html tags in your heading.
