How to increase the density of a keyword without being punished

A site's keyword density is higher then the site's ranking the more benefits, of course, this is also a degree of about 2%-8% between us here, how to effectively increase the density of keywords and will not be the search engine penalty

I. Title

Put keywords in the title will directly affect the ranking, so we should put the more important keywords in the front, the rational use of title tags can be very good for our keyword density increase. Of course not in the title stack a large number of keywords generally 2-3 for the best.

Ii. META Tags

In the site of the keyword and description of the label, we should also put the keyword we need, this role and title tag role is the same, he will directly affect our site rankings. I remember yesterday to help a friend check the site, found that his site keyword and description tags are written "home" I asked him if you want users to search the home page into your site? Asked clearly, he did not know the role of these two labels. General keyword set 3-5 can be, set too much will not make our keywords can have a good ranking, but will let our home page weight too dispersed. The best way to describe the label key is to repeat it.

Third, picture description

Search engines do not read pictures, but he can read the description of the picture, so adding a description in the picture will also be counted into the keyword density. The description here is not to let us accumulate keywords in the picture, but in the appropriate time to add 1-2 keywords on it.

Four, the bottom copyright statement

We can change the bottom of the copyright statement to our keywords to improve the density of our keywords, and the appropriate keyword bold, italic and so on. Not too much.

Although said the site's keyword density high on the site's ranking is very good, but we must remember not to accumulate keywords, if the accumulation of the situation, then the site was the search engine down the right he is entirely justified.
