Magento and WordPress Integration – Why Bother?
A lot of times before you finish developing your Magento store, it just so happens that you are already running a WordPress blog. This means that you actually have an online presence already established when you launch your new store. Having both a store and the blog is successful Magento and WordPress Integration.
Also, after your store is live and selling, you will still want to maintain your WordPress blog. This usually takes you to the point of decision: should I just leave it where it is, or should I integrate it as a blog inside my Magento store? This is not an easy answer, as the right answer as always, is that it depends.
