In promotion, the most important thing is content. If you just have a lot of subscribers, but they will not interact with you on a social network, then Instagram will assume that your posts are not interesting and then it will stop showing your posts in the news feed of users. You can comprar seguidores instagram who may be interested in your content. There are other ways to attract customers.
For example, targeted advertising. Targeted advertising can only be run by business account owners. You can connect a work profile via Facebook, you can view account statistics and run ads. Statistics show the number of impressions, coverage and other indicators of publications on the page.
Another way is to buy advertising from bloggers. Many people trust the opinion of those they read on Instagram, and such advertising often looks like an honest review.
Whichever way of promotion you choose, it requires financial investments.
