Was taking months to work with Drupal and I have my own blog in Wordpress yet. It makes me stop and start to study really what is the better, for a correct SEO positioning.
I dont want migrate my blog in two days to lose our ranking, havent sense, there are really good mentions to our blog from some important sites as jQuery and I dont have so much but.. its important to save me prefered indexed information anyways.
There are a quick mode to work bringing information from other data containters, the node_import module could makes easy the task. The idea is to make a source CSV where whe can identify the information for our tables. We can choose the content type and relate one of each source field.
Well, go:
