The formula for calculating PageRank is patented and a closely guarded secret; according to Google, PageRank is determined by looking at more than 500 million variables and 2 billion terms. But even though you can’t know all the details of Google’s formula, there are some things you can do to increase your PageRank.

1. Inbound Links
   The most important factor in determining PageRank is the number of high-quality websites that link to your webpage. Think of it as a voting system: when one page links to another page, Google considers that a vote for the other page. The more votes a page gets, the more important that page must be and the higher its PageRank. Votes from more important pages are considered more important, meaning that a link to your site from a page with a high PageRank will increase your PageRank more than a link from a page with low PageRank. Links from sites that have content related to your website’s content are also more valuable than links from unrelated websites.
2. Internal Linking and Structure
   How you structure your website is important to maximizing PageRank. Here are a few tips:
   • Make sure your website has a clear hierarchy and important links are made up of text rather than images.
   • Don’t let the structure of your website get too “deep”; having to follow several links in order to get to a page from your site’s homepage generally decreases that page’s PageRank.
   • Make sure every page is linked to by at least one text link, and avoid dangling links (links to pages that don’t contain any links themselves).
   • Include a site map that links to your website’s important pages.
   • Don’t put too many links on any one page.
3. Quality Content
   Having a lot of interlinked pages is good for PageRank, but only if the content on each page is original and useful. Good website content will encourage other websites to link to your pages (see Tip #1), and Google penalizes websites for containing content that is duplicated elsewhere on the Internet.
4. Use SEO Techniques
   Don’t forget to optimize for your target keywords, so Google knows what your website is about. Good Search Engine Optimization is key to improving your search engine ranking and is a factor that Google takes into consideration when calculating PageRank.

Following these tips should improve your Google PageRank, but be prepared to wait a few weeks before you see results–with the millions of websites on the Internet, it will take time for Google to reevaluate your website.
