I'm launching a new website within the month. The site will start out as an information/how-to site and may eventually turn into small sales related to the how-tos. I'm considering a brick and mortar and this new website would be the site for the B&M if I go that route. If I don't go B&M, then I plan to build the site and income from Adsense, small sales and then sell the site sometime down the road.
So, would like some advice along the lines of things I must do and things you wish you had done had you known what you know now but you're too far down the road to turn back now, particularly with SEO in mind.
