Navigation Links:

Many people follow the habit of using pictures for creating interlinking but this can be replaced by adding alt attribute to your images. But by using navigational links you can create a lot of density in the keywords by using appropriate Anchor Text. In your navigation if you want to link to Search engine optimization page by using the anchor text search engine it will be better than just using an alt attribute to your images.

Breadcrumb links:

This links are the one which appear on the top of the pages which provide interlinks and sub links to different pages. For example in the website netZtrack .com under the link products we have links naming search engine optimization, social media marketing, pay per click management, and website designing.   This in this way includes lot of keywords which help in creating the traffic for the site.

Subject area links:

Content websites having different texts has got lot of subject which they can use as there anchor text. This is most useful in terms of websites which have a lot of subjects or in other words a lot of content to read.

Individual Page links:
