Create an Instagram page, you can receive a lot of collateral benefits on Instagram from your activities on Facebook.
Post at a minimum of 4 to 6 times per day. And spend a few days populating your page with posts before you start any type of promotion.
Boost every single post you publish. Use small amount per post. Usually this is $5 to $10, for just one day (images will get the most engagements in terms of reactions, shares, and comments. Videos will receive a lot of views, but less actions.)
