The Buffer blog has published a really useful post looking at how to make the most of Instagram, by using its search function. One particular piece of advice often missed comes from photographer Allen Harper:
Some hashtags are vastly more popular than others; however, popularity doesn’t always translate to effectiveness. For example, you’ll notice that #photooftheday, #like4like, #instagood, #iphoneonly, etc. are extremely popular. Unfortunately, since so many users throw these similar tags on their images, it means that their photos are buried in the pool within seconds and become virtually undiscoverable.
Nothing earth-shattering, but great, solid advice that will last.
