Another link on your personal Facebook profile
Put a URL to your Facebook fan page under the 'Website' area of the Contact Info section of your personal Facebook profile.
Add your Facebook Page url to your email signature
Think about how many emails you send per day. Now imagine each email you send is a chance for someone new to find out about your fan fan page … Stick your Facebook URL in your email signature along with a 'Like Us' call to action, and a reason why people should visit and 'like' your Page, eg "Like us on Facebook for exclusive vouchers and discount codes!"
Blog about your Facebook Page and give reasons why people should 'Like' you
If you have a company blog, why not create a post specifically to promote your Facebook presence?
You should give something interesting to your readers to like your fan page and in your blog post for instance, exclusive offers, news to their feeds, sneak peeks atcoming products. Do not beg them to like you; just give reasons why they'll benefit and watch the like box numbers trickle upwards.
Add a Facebook 'Like' box to your website or blog
Get the code for a Facebook Like box (Google 'Facebook Like Box' or visit https://developers.facebook.com/docs/reference/plugins/like-box/ to find the Facebook Developers page) and embed this in your blog or website's sidebar. When you set the box up, make sure you check the options to 'Show Faces' and 'Show Stream'. This will ensure that the Like box shows anyone who sees it the profile photos of any of their friends who already like your page, as well as a scrollable, clickable preview of your most recent status updates.
Although most Facebook "Like" boxes are placed in website sidebars, I have read of some people's success in inserting them underneath blog posts instead. In this position, the widget works as a call to action like "Did you enjoy reading my blog post?" Then, click "Like" to keep in touch on Facebook … "Why not experiment with your" Like "box position to see if you notice any difference?
Promote your Facebook Page in your car, office and on business cards
Anywhere you can display your Facebook fan page address is free advertising for you. Just think how many people would see a car bumper sticker with your address on, or sign in the office or store window asking visitors to 'like' your page. In addition, combine offline and online by letting the people you meet in real life know about your fan page by getting its URL printed on your business cards.
Add Your Facebook Page URL to your Twitter page
Lots of tweeters still use the web-based version of Twitter, and your profile background is a prime piece of web real estate just begging for you to take advantage of. Cross-advertise and use Twitter to promote your Facebook page, both as an image on your Twitter background and in your Twitter profile's bio if you have room.
