20 Ways to increase your facebook likes and engagement

Advertise on Facebook to get more “likes”. This is the quickest way to grow your fan base.
Rotate your ads “DAILY” people get tired of hearing the same thing in conversation so change your ad! Conversion (CTR) rates can drop by 50% after the first 24 hours. Do not “set and forget”
Add Facebook Social Plugin Box to your Blog and Website (60% of my “likes” are achieved this way)
Free exclusive video that can only be viewed if you like the page.
Run a competition. Everyone likes a competition
Make it obvious on a custom landing page by providing a big bold “Like our Page”
Initially ask friends and family to like your page. A bit overdone but essential at the beginning
Offer a free e-book to obtain a “like” (just like you should be doing for email subscriber acquisition)
Post content from your blog to Facebook whenever you write a new post. Facebook users love receiving new content on Facebook without having to go looking for your blog. Treat Facebook as an extension of your blog.
Provide enticing high resolution photos. Compelling photos that are appropriate for your target audience will keep them coming back and make them share and so drive more likes from their friends
Ask questions regularly using Facebook’s native question app.
Include a link to your Facebook page in your email signature
Provide a compelling welcome video on your Facebook landing page
Simple but often missed: Add a “follow us” on Facebook button near the top of your website and blog pages
Create an incentivised “Like” page that gives people a reason to like your page.
Include the Facebook like button on your email HTML template so that people can like your Facebook page from the regular email newsletter
Add a large custom banner to your blog and website asking to “Like”
Add a link to your Facebook page as one of your three LinkedIn website links that are part of your LinkedIn settings in your profile
Add a newsworthy update that is relevant for your industry or market niche to your Facebook page every day
Offer “Special” including discounts to Facebook fans. The majority of Facebook users “like” a page to obtain a discount.
