A witty person will never go for buying facebook likes as they are costly, considered wasteful and don’t have large benefits. By following the stated ideas you can attract as many likes on you page as other can generate by paying hefty amount.
If you also run your website, then you should introduce a like button or tab on the website that will promote your facebook without any cost on all pages of your website. If you also have accounts on other social networking sites such as twitter or Instagram, invite your followers from there to your facebook page.
In general users are tempted to invite all the people in their friends list to like their page. But remember that it is of no use to invite those users who have no interest in your brand. They might like your page as you asked them but they will never be interested in interaction with your posts. So only invite those people who have some kind of attention in the content that your page posts about.
If your want users to go excited your facebook page and visiting it regularly, one immense idea is to organize some kind of contest or a promotion. When users will participate in those contests, they will also share it with their friends and friends will also like to join the contest. In this way your facebook advertisement will increase a lot.
You should not only be promoting on websites and social media sites but also in your daily life in offline mode as well. Those people who pay visits to your office, you should be inviting them to your page. Also in a few words describe the content of your page to those people whom you meet on routine basis at work or school. You can also share link of your facebook page on your visiting card and on the bill receipts or on some vouchers as well. Create a URL that is very easy to keep in mind.
The main priority of yours should be to remain calm and interesting depending upon what you post. You should give special discounts or bonuses to regular users. You can also post general news that will also attract few users. Do not copy and paste someone else’s content. You can be humorous sometimes, and can share jokes as well. Remember first make a plan that what exactly are you going to post. Never post any uninteresting stuff on your facebook page in a hurry.
If you are newbie, and you can afford to spend little money, then spend it on running ads. If you were willing to buy facebook likes, then it is much cheaper and better to buy facebook ads. For that you can even start with little amount of 50$ that will attract 100-200 new fans. On this low payment to facebook, you will see good increase in likes.
