Don't submit similar articles on your own website. This can damage the position which you have. This may also dilute your link count and drop your site's page ranking. Get a seo company to provide fresh content from time to time if you are not in a position to do it.
A web site metatag is where you add a description of what the page is about. Rather than a few words just like you might include in the name label, the meta tag has space for some well-constructed sentences. For powerful search engine marketing, do not merely repeat what you already have within the name label!
