Here is an interesting article which tells you in no uncertain terms how to maintain your blog audience, and its from the Sponsored Reviews blog, no less. You can read this interestingly elaborative blog post written by Jarrod Hunt at 27+1 Tips for Building and Maintaining a Blog Audience. There were several suggestions were made in order to not only gain but also ensure that you have a consistent number of blog visitors. Things like making sure that SEO principles are applied to your blog template, getting the right blogging platform (I would recommend WordPress) and staying on course and blog regularly with proper grammar and little spelling mistakes are some things which may already be familiar to some. I do, however, notice that the Sponsored Reviews URL relies on the default WordPress link, so I would like to suggest to them to ensure that they should check out the readable permalinks in order for search engines like Google to spider the blog quickly and efficiently.
I do feel the need need to add one more suggestion of my own on how to maintain a blog audience and that is to uphold the maxim: write the truth and nothing but the truth. There is no point pretending to be who you are not on your blog while in real life you are actually somebody else. As the way things will go, there will be those who do not like you not because your opinions lack merit, but because they are infuriated that you are actually on the scene conveying opinions that are opposed to theirs in the first place.
The only way to deal with these sort of people is just ignore them and move on. These people may even have their own blogs and if they see that you are captivating an audience, they will try to shoot you down via their own blogs. But ignore them. If they want to complain or make noises or jump up and down trying to get your attention, simply write about something else. Your audience will love you because you are who you are, despite external pressures.
