In my opinion these paid likes doesn't matter for our sales. unless we buy an ad area from facebook and publish our page thorough that. In my suggestion by publishing page URL in concern groups and related area is matter to you.
Get a lot of friends and post your products and services to your wall, hoping your friends and friend's friends will see them too. Once a friend asking about your products, keep contact with them via messages. Ask them to 'not receive' your offer again if them is no more interests with your products. Now, how to add friends? I was use add me groups to add friends and it work for adding friends, but I agree this is not a real fans, they just want to add more friends like us. Another way to add friends is using tool like fb adder. Now I realize that online promotion is not as easy as a couple years a go.. There are many ways and media now but the competitors also hugely increased a lot..
You can promote your site through Facebook by posting or sharing your link in your wall or your friend's wall. You can also use Facebook Ads but you have to pay for them to advertise your site.
Some good techniques that I've learned is posting unique content. Post interesting information about your product that will get the viewers engaged on what they're seeing in their news feed. Always interact with all of the people that comment on your posts, connect with them and make them feel that they can relate to you. What is good as well, is try to find other pages that relate to your niche. Ask them if you can partner up with them, so when they see some interesting stuff on your page they can share it. That will add more volume to your page and the more it will get exposed.
Promote through facebook groups. Go to facebook and search facebook groups with keyword say "baby sign language" and post good advice that links to your blog post example " hey I just found a good article on ____ check out my blog post" something like that.
You can promote your website by sharing him on those walls who have 5000+ friends n you can also share on different groups...Its one of the best way to get genuine traffic towards your website easily.
This is a method that I found out about yesterday from watching Pat Flynn. He promotes his facebook page with a domain name patonfacebook.com . I thought that was awesome so I went and bought me one. chrisisonfacebook.com . he has some awesome facebook marketing techniques and set up too. The place I found it was smartpassiveincome.com/timeline-facebook-pages-guide/
post interesting information, pictures and videos also, a lot of the time someone might like a picture or video, then they will read what its about and therefore visit your site, but if there is just writing it may not catch as many people's attention. Posts don't always have to be about your site something interesting or different will get people to notice you and then get to know what your about. There are no magic bullets, just keep at it.
I have spent thousands of dollars on FB ads and FB contests (have given away iPod touches, iPads, cash, gift cards) and I am very disapointed with the number of new likes and traffic for the amount of money spent..
I just bought a domain name linked to my facebook page and I am promoting it like promote a facebook page. I know the qeustion was How to promote site through facebook but if you have a facebook domain name like http://chisisonfacebook.com mine, you can kinda kill two birds with one stone I think.
Than you, and yes it could be one way or many ways. You can add your website to your facebook page or affiliate offers.
