Use Popular & Relevant Hashtags
Search Google or Webstagram to find popular hashtags, which are used to organize photos. You can then use the relevant trending hashtags to you or your industry to gain more visibility for your photos, which should generate more interaction. For example, the top 10 hashtags are: #love, #instagood, #me; #like, #follow, #cute, #photooftheday, #tbt, #followme, and #tagsforlikes.
You can also use Instagram autocomplete to find relevant hashtags for your industry.
While hashtags are an important asset when attracting new followers, you don’t want to go overboard. Instead of posting an entire paragraph of hashtags, try to select one to three hashtags per photo. Any more than three will seem spammy.
