Well, I started a new blog, and I'm wondering, do you hop straight into building back links (which is what I meant by SEO, I already have it optimized in terms of content), or do you wait a bit? My blog is only 3 days old, I haven't built a link to it yet, and it has been indexed. Should I wait a week before I start or what? I know I knew someone who would say post at least once a day for 20 days before building back links.
Well, If you gain few quality links early no harm either, a month after you may plan a campaign. I suggest better work on building quality contents and gain 5/6 quality links. I can't see any reason posting a daily blog, but creating useful contents over a period of time will get you lots readers and natural links. [IMO]
It's no harm if you start SEO camping form today. As first you will get back link it will give your site quick ranking. It's no harm to start SEO from the day of build site
You should start now, as was mentioned get a few relevant back links to your blog. Be consistent. I know some who have had sites ranked for "long tail" keywords within a week or two.
