SEO Keyword density and Internal links

Set Keyword Density
The search engine determines the relativity of the content through keywords within the content. If your content includes the right density of keywords, that is the percent of times your keyword appears on a page relative to all the words on a page, the content has a greater chance of displaying in the search engine pages when a user types related search keywords in the search engine’s search field. The placement of the keywords should be natural and not affect the quality of the content. The optimal keyword density varies, but generally 2 to 5 percent is a good range. It is important to check the 
keyword density for each of your website pages. This helps you identify how well the content is optimized for search engines. You can use many tools to check the density of a specific keyword on your website page; one example is www.gorank.com/analyze.php.

Use Internal Links
Internal links refer to the links on your web page and links to other relative content within the same website. For example, you can use a keyword in an article as a link to a related article on the same website ( example: view our Magento Eccomerce SEO.) These links are very important because the greater the number of internal links you have, the higher your website rank. The internal links play an important role in increasing page views because website visitors click internal links to view other pages on the website. Also, you can add internal links to a web page by mentioning related topics. There are different web tools that help you check the internal 
links, such as www.google.com/webmasters/tools and www.seochat.com/seo-tools/site-link-analyzer. Unlike the Google Webmaster Tools, SEO Chat lets you check website internal links without creating a website account.
