remember when both initially creating your blog and then promoting it to others.
While in the beginning blogs were created more for personal use, as the internet and businesses develop more and more companies are using blogs to help promote their business, but the foundations remain the same:
First and foremost keep your readers in mind; even if you have a blog that is full of nothing more than your personal rants, if you want people to keep coming back you need to make it easy to read and understand. Remember that in this day and age people using the internet will often spend a lot of time just skimming over pages so you need to capture and then keep their interest, the best way to do this is to keep your writing clear and concise, while it doesn’t need to be grammatically perfect (at least for a personal blog) it should at least make sense.
Try to provide useful and relevant information for your readers, no matter what subject your blog is about if you can give the viewers the information they want or find helpful they will keep coming back for more.
