I don’t know much about Instagram so this is going to be a short one. I won’t even bother with keywords. Let’s see if “writing for people” really works or if Google is full of shit with this recommendation (we both know the answer).

Here’s a short guide.

1. Compile a list of hashtags you want to target. Don’t use hashtags that are too popular, you need the ones with the number of posts below 10,000. Hint: find more than one hashtag, duh.
2. Add these hashtags to every post.
3. Buy likes. 50-100 per post is usually enough to secure a place in “top posts” by hashtag
   

   In case you don’t know what a top post is.

   4. Repeat when necessary, try to keep at least one of your posts at the top at all times, it’s simple.

Is this expensive?

No, there’s a reason it says “cheap trick” in the title. Here’s the price I pay per 100 likes:

100 likes are usually enough to secure the spot as I already mentioned. And you can do so for more than 1 post. My personal record is holding 6 out of 9 top post positions for my hashtags. Not sure if there’s a limit though, so go for all 9.

What risks are there?

I don’t think there are any. If you could get banned for buying likes this way I would buy a ton for all of my competitors. But don’t take my word for it and proceed at your own risk.
