Great content. Although I disagree with ‘the best times to post’ section. It is important to understand your audience. For example, if your brand/business is in high school, there will be low engagement until 2-5 when they are out of school. I highly suggest using instagram analytics (a subsidiary of facebook analytics) which gives you all of the details on when your followers are active. https://www.facebook.com/help/788388387972460
Real estate can potentially earn you more money than the stock market. Over the long term, investing in the stock market will earn you an average annual return of 7%, adjusted for inflation, according to a number of studies. DiversyFund can’t guarantee how its investments will perform in the future — no one can — but historically, it has earned an annual return of 17% to 18%.
The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you.
