I feel getting in touch with professors who specialise in your research interests plays an important part in getting accepted. This way, you can inquire whether the prospective programme focuses on the research you have in mind. Personally, I will email the professor a brief outline of my interests and then the research I hope to do and ask for their opinion.
As to getting rejected, I was rejected flat out by about a dozen places this time. More than half of those rejections were from earlier applications where I was still unaware that we can actually get in touch with individual professors. Luckily for me, I received a couple of offers later on, and for those applications, I tried to establish some correspondence with the faculty members.
Don't lose heart. Take this time to focus your research interests and find programmes which fit you. Hope this helps.
