What do you use for SEO? Any software or taking any professionals pay service
for good SEO as it's one of the most important thing for site popularity and page ranking?
Actually, I have done neither. I wouldn't know how to use software to make my SEO better. I do not understand how the software works.
Basically, I write to the interests of my readers. I feel that if I give them information they need and supply it in a better fashion than other sites, they will come stay at my site.
I try to make my content relevant to the topic so I kind of think my SEO works in naturally.
One of the best things that I ever did was buy a bunch of SEO related books from Amazon. I learned a lot from these books. If you are looking for a software product which can help you with SEO then you should have a look at the free version of Web CEO which includes many great tools.
