I always assumed SEO was simply a buzzword that meant "using content that makes sense". Obviously it gets a little bit more complicated than that, using realistic search terms in header tags and things, but that was a far as it got.
I was speaking to someone today about this, and they said how there's a second aspect to web design. Submitting sitemaps to Google. A weekly sitemap submission to Google was a way to seriously boost rankings.
Is this true, and how can this process be automated?
