The crucial thing: Always remember to add hashtags to your new post no later than 10-15 minutes after the publication.
Our tool starts performing the analysis right after you post new content (within the first minutes).
At the next stage of analysis, it monitors how the photo is positioning for given hashtags in time. It scans the current position in recent posts for these hashtags.

That’s why when you change the hashtags – those changes aren’t taken into consideration, cause the tool has already downloaded previous data (with hashtags).
