Can anybody tell be how to increase page rank of a site .mine is 4 years old site http://smscollection.com but only has page rank of 2 in google
Pagerank 2 isn't that bad and the good news is its a start. What would really help is some links pointing to your site. If the sites that link to you have pagerank and do follow the links then this could quickly increase your pagerank. Esentially you are looking to increase the authority of your site and the quickest and easiest way I know of is links.
It doesn't depend on how old your site is. Its more or less based on the votes you get from other sites. if you cant create killer contents that people cant resist linking to, I suggest you start buying ads or links. But be weary. buying links, if caught by Google algorithm will penalize your site.
I managed to get a PR of 3 on one of my sites in a couple of months with several high quality links - it's not volume, it's quality. I had to reciprocate the links, but it did no harm at all. Just find similar sites with partners, and email around. I got a really good response from the folks I asked.
start link building and change your site content if you not got visit. make friend in social bookmarking sites. Use twitter.
The only way to increase pagerank is to build on backlinks, especially linked from high PR sites. Link baiting is a very good way to increase backlinks, and effectively your PR too. How about creating a tool with a link back to your site : PP ?
Try to put fresh content and regular update the blog/site. If the content is not fresh crawl rate of the website may decrease that is also one important factor in calculation of Page rank.
Do you need a high pagerank or a high search engine rank? Well a high PageRank doesn't mean that you'll have a high rank on search engines. It's still about anchor text links. Keep them varied and you will be doing a good job. People say I will sell links from high PageRank blogs/sites. So I need high PR. Well a high rank could give you more benefits than a high PR, and well even Google is now penalizing sites that sell PR. So just be sure what you want and what you want to do!
Try social Bookmarking, directory & articles submission, you can try link exchange to increase your page rank.
hmmm you have an old site but do you have lots of backlinks? PR heavily depends on the amount of backlinks your site has.
Why is the Pagerank all the time? Page ranking is ust a small part of your SEO plan. The ranking algorithm is complicated a lower page ranked site can actually surpass a higher ranked site. Rethink your SEO strategy. Page rank is a great determination of websites popularity; however, it won't be the major factor in gaining website traffic. I don't even worry about it anymore. It bounces up and down all the time. As long as my traffic is going up that's all that matters.
