Does SEO all about merely the number of links pointing to your webpage?
I am asking this because even if we talk about so much other things, end of the day, we are only building links to our webpages. Sometimes we getting the links for free thorough bookmarks, comments, directories that will fade away as time passes by.. or through paying some amount we are getting the links. So is that all about how many links I am getting?
And about the quantity Vs quality of links, do I still have to run after web pages that have PR more than 3? Or I can links from the low profile websites also? Because I am seeing some people out rank others by simply doing the link building, doesn't matter if the PR is high or low.
Your suggestions and thoughts would be a lot helpful for me.
