Google fixes a rank for each website based on the keywords in domain name,content,design of website, TLD, Domain age, number of visitors,loading capacity etc.Over 80% of the Internet's users go to a search engine before reaching a web site.When someone types a product into a search engine, and if our web site is listed at the top of these results, they may visit our site and chances are there that they may become our customer.
You can increase pagerank by good quality in the site/blog ,regular updates,interlinking posts,SEO methods,Good website design & uptime,social media,affiliate marketing etc.
SEO(Search Engine Optimisation) is the best and steady way to improve a site's page rank.I have used the SEV(Search Engine Visibility) from XnYnZ.com
as they provide keyword and suggested topics,submit the site to over 100 search engines and also provide reports which eventually improved my website traffic.
