One of the most important things to keep in mind is that it doesn't happen overnight. I have had my Instagram page for about 5 years. I did not know what to expect when I made it, especially since in was nothing like how it was before. It used to be personal, photos of what I was doing on that day in that moment.
My page content has changed multiple times. From what I can remember it went from personal to longboarding to art to landscapes to portraits. I've even abandoned it a few times to try to make other ones. Instagram pages are very niche orientated. The accounts with consistent and similar content are the ones that grow. Every time I chose to leave the account I have hurt my engagement. People don't like change.
One of the other things I've learned recently is that they also don't like you deleting your own content. At the end of last year, I chose to purge my page of all the "bad" photos I posted, which caused my engagement to drop. I started this year with only a fraction of what I had at the end of last year.
I would consider my page now as much a portrait page as a landscape one. I want to grow it into a portrait page.
I had two goals at the beginning of this year, which will branch out into a few more that I will talk about eventually. The first goal was to take more portraits. I think that I have been doing a pretty good job of it so far. The second was to meet more people. Lately, I have been doing ok at this. Going to meetups has really helped me meet others. Doing photoshoots has also helped me. One of the things that I wished I had continued with was the stranger's challenge. It was supposed to kill two birds with one stone by meeting others while taking portraits.
All I can do is continue to do what I do and do it as best as I can. These two are the two photos with the highest engagement of my Instagram right now. Another one of my goals that stemed from the two was to have a portrait be the most liked photo on my instagram. And yesterday it happened with the photo of Taylor.
