The 3 most important HTML tags in search engine optimization are title tags, header tags, and ALT text. Let's take a closer look at each HTML tag.
Title tags
Most of the major search engines give the most relevance to keywords in the title tags within the Web page. As such, every page should have a title tag. In general, I have found that short keyword rich descriptions in title tags work best.
Good title tag:
<TITLE>Search Engine Optimization</TITLE>
Not so good title tag:
<TITLE>SEO.com - Search engine optimization tips, tricks, news, resources, tools and much more besides!</TITLE>
Header tags
Many of the major search engines place a lot of relevance on keywords in header tags (H1, H2 and H3). As such I recommend that you sprinkle keyword rich header tags on your Web pages.
Sample header tags:
<H1>Search Engine Optimization</H1>
