If I buy a article database from other, how should I add them to my site?? What is the best if:: 1. day by day post a few article. 2. Add all of them to the site once Thanks !!
Do it day by day - Google loves to see fresh content all the time; otherwise you risk losing your daily (or hourly) crawls!
Day by day is best, but there are some programs that let you load the content ahead of time. Wordpress for example will let you load up all the posts and then set the time to go live in advance, which is nice.
