WordPress Speed Up Service | WordPress Website Maintenance Packages I have read an advice before that in order to improve your SEO, you need to submit to article directories. Is this still applicable today? Do you still submit to article directories? If so, what types of articles do you submit? Are they unique articles or articles that are already found on your blog? Do they need to be of high quality or is it okay to just submit low quality articles? I'm asking this because I saw a wordpress plugin that allows you to use articles from The Guardian with the condition that you don't alter the content - the links and the adverts, etc. I wonder if this is doing well for the Guardian as it definitely would result to a lot of duplicate content.
