The recommended standard density

The recommended standard density for body text is 3-7% for each keyword you optimize on that page. Basically, this means that every keyword or key phrase should repeat 3-7 times for every 100 words. If keyword density goes over 10%, it looks suspicious to search engine spiders. Each web page should generally be optimized for no more than three keywords or phrases.

When the keyword is located in HTML headings, for example between <> < /h1 > or <> < /h2 > tags, it is considered important by the search engine spiders. Yet, putting keyword in the heading tags is not good enough, if the web page does not have actual text about this particular keyword.

Keywords that are located in the beginning of the web page text also matter, although not as much as keywords in the title or headings. The most important thing here is to understand that beginning of the page does not mean the visually viewed first paragraph of the text. So, check the source of the page in order to be on the safe side.

Spiders don’t read images; they just skip them with one exception. They can read text that describes the image in the ALT attribute of the <> tag. If there are images on your page, fill in the ALT attributes with some keywords about images that you describe.
