The best tip I can share as I ponder coming up to our 3 year mark at MandM is to set yourself realistic goals about how often you will post and try to stick to them; try to make it consistent to keep your readership happy.
For most of us it is not viable to post 5 entries a day but I find even if your readers work out that you will post a couple of times a week, every week, they will still come back.
Change your theme to be more SEO -ized. Most blog systems use horrible themes by default (ie: Wordpress). Even taking out the monthly archives link might help if it's good for readers too
First choose that kind of blogs which are allows you to put keywords.
Regular Update your blog.write your blog which must related with world exclusive news.by doing this you will get traffic.
to be updated about the topic that one has made with his blog, he can subscribe to google alerts and receive alerts about new content created regarding or in relation to his blog topic. by doing so, the author or the blog owner will also be updated on the new "stuffs" that are going around in his topic niche and can even create an up to time article about it. that is what I do and by doing so i am able to create fresh and up to date posts with it.
