I tried to buy instagram likes via SMM-World several times and I can share my experience. I will say right away that as soon as you start using such services, it is worth remembering several important points. Firstly, in terms of “indicators” you will really see how the number of likes grows, but in terms of engagement, everything is not so rosy. The likes that you buy are, in most cases, just bots or fake accounts. They do not leave comments and do not interact with your content. This creates the illusion of popularity, but in fact, does not give anything. Instagram is now actively monitoring activity on the platform, and if the algorithm notices that your posts are getting likes from inactive accounts, then your engagement will decrease, and your posts will be shown to fewer people. In the long term, this can even lead to your account starting to lose coverage, and all those likes that you bought will not only not bring any benefit, but will also harm your promotion.
