I have purchased a domain for which I will develop a web site in a few months. I am wondering if I go live with a 1-3 page site now, will this start the clock with Google for when they will allow the site to rank? Or should I wait until the site is fully developed and then go live?
Put up the content As long as you have unique and fresh content, it will be fine. Use robots.txt to block out the bots for your 'Under construction' pages (if any)
