One strategy that works out quite well for me is studying dead or old websites. When there is an old blog that continues to generate some traffic despite not being updated in many years, I see what pages it still ranks for. There usually is always a topic or niche area worth investigating.
Do not search for the perfect niche right from the start. Identify a recuurring problem for which people need an answer and which can be answered better than the other answers currently available on Google. That is when you find a gud niche.
I mostly begin by finding issues that have been solved. Try to go through some online forums and even the search engine suggestions to see what issues keep arising and if the solutions provided are not effective. It is usually there that you can find a great opportunity in your niche.
Typically, I begin by looking at issues that are currently being worked on instead of seeking out some random niche. The way to do this is to check out forums like Reddit, Google searches, and more for actual questtions, and see if the pages ranked currently have holes in their content or if they are outdated.
One easy way would be by findiing out which topics interest u then seeing what kind of searches ppl r doing actively. U will have to find out which kinds of questions they r asking as well as sub topics that have not been written about much yet or have become old fashioned.
