Hashtags work similarly to keywords in that they help your pins be discoverable by Pinterest users. In this Ultimate Marketer’s Guide to Pinterest, hashtags have been described as being more of a categorical element, and less of a tool to help your content show up in Pinterest search results, so don’t rely on them as heavily as you would keywords to get your content in front of searching users.
May I ask why you use 2 different scheduling companies to schedule pins ? I’m using boardbooster to schedule my content to group boards and my own boards and also pinning others’ pins on my own boards. 70 % are others pins and 30% my own. Im pinning about 60 to 70 pins/day and the follower growth has been miserable. I’m also on group boards (currently about 10+ group boards.working on joining more). I’m trying to understand if it helps to use tailwind too vs just board booster
