Have anybody used http://like-ex.com/ for increasing fan page likes? I'm just new for it. Its gud to use?
The likes you get are mostly from fake accounts from people who use the same page. See it works like this: You give your account access token that is then saved and later used for everyone else using the same service. Since nobody want's to use their real account for such "illegal" service, the likes you gain are totally useless unless you just want to boost the numbers. Boosting numbers is not good, because then facebook will determine your edgerank poor because those fake profiles never interact with your page. Low edgerank = low reach = dead page. So there you have it, you're welcome.
Rather than using a tool to increase fan page likes, with 'fake' fans, do the work to earn 'real' fans that will actually interact with your page and become customers. Contact your email list and ask them to like your page and write on your wall. Link your social networks together so your Twitter followers know you're on Facebook and Facebook followers know you're on Twitter, etc. If you have print media include your Facebook and Twitter info. Run contests on your social networks. Ask your current followers to share your pages with their friends. There are a lot of options to increase your fans. It might take longer to increase fans naturally than if using a tool, but the fans you get naturally are more likely 'real' fans that will stick around.
