This is such a useful tool if you want to get the most reach out of hashtags on Instagram, I highly recommend hashtagsforlikes. Its also very cost effective, only being $2.5 per week.
This helped me grow a serious following on Instagram, I didn't realize the importance of hashtags, this tool helps me use relevant up to date hashtags targeted towards my audience, growing my reach.
Great service, customer support was awesome if I needed anything to do with my account. I love how the dashboard offers so much value and new things are being added all the time.
