There are many companies that offer free likes for your social media accounts. You can use these free likes in any way you want i.e. for your business, to boost a post that you want more audience, or simply to boost your online presence.
Depending on the company, you can get free likes by sending the company the link to the post you want. For companies that offer free likes, there might be some charges for other aspect such as you may need to sign up for an account and register for the package offered with that type of account. The registration fee is usually minimal and you can boost a designated number of posts. There are also companies that offer unlimited post to be boosted, but the registration fee might be slightly higher.
You need to understand the volume want and what do you need it for. It’s better to go with the package with the lowest number of boost so you can monitor the response from your customers before moving on to higher number of likes from the company.
