Posted three new photos today with hashtags from the app he mentioned. 10 new followers, which is probably all I've had in the last 2 months. Interesting!
That app is shit, great for high volume tags but do you really want to be in a oversaturated space? Use Hashtagify for niche research and Websta Top 100 for some volume.
That and slamming #tfb, #followback, #f4f into the tag orgy helps. Enjoy 50-200 likes and 15-30 follows/post.
