For a new pinterest account to start taking off, you have to be patient because this is not Instagram, the first month is usually the hardest, it is the phase where the algorithm is testing you and your impressions are very low, at this stage, the important thing is that you focus on publishing fresh pins daily without expecting to see immediate results, it's normal to feel like you're talking to yourself, but Pinterest needs that time to understand what your content is about.
The real movement begins to be noticed after having been active for a couple of months, by then the impressions really start to rise and you may have your first viral pin that gives you a big boost, most accounts only start seeing consistent traffic after several months, which is when old pins you left archived start ranking in searches, it's a snowball effect that accumulates over time, it's not that one day you wake up and everything explodes.
Of course, it all depends on you being consistent, if you publish a lot of pins one day and then disappear for weeks, the algorithm punishes you and you have to start almost all over again, the recommendation for a beginner is to start with a sustainable rhythm, even if it is one pin a day, but without failing, in the end, on pinterest the one who wins is not the one who publishes the most, but the one who never stops publishing.
