I know some of you may not yet know, so I think it is appropriate to discuss here the advantages and uses of Data Mining in SEO. We as bloggers, website owners, webmasters are all interested in driving traffic to our website and I think data mining can really help us in our effort to attract more visitors to our blogs and eventually create sales. How do we do this? First we need to find a good place where we can access what most people are looking for or interested in at a particular time and place that's when data mining algorithm comes in and we should know how we can inform those people that we have a nice blog that can supply the information they are interested or we can optimize our blog/website better for them to find it more easily. I hope this helps.
I know keyword research, but keyword research is rather based on historical data and not just keyword, how about how the people are talking about the keyword, we should know if they like, hate or just planning to buy, etc.
