No, not in any way whatsoever. Our members search engine optimize their websites and have seen how much the search engines love IconoSites websites. Our clean code is exactly how the search engines like it, which means you rank higher.
The reason that pointing a domain does not affect optimization is because technically your site is hosted with us. The reason we use the term "pointing" is because we dont provide traditional web hosting services such as FTP access, email addresses, etc. We only host the website itself. And it doesn't matter where your website is hosted -- all that matters is that your website is live on the internet, so that the search engines can crawl it.
