• Superclean provides links to your new site at supercleandesign.com. We will create a portfolio page and often a case study... all optimized for your target keywords and phrases.
• If we can come up with an interesting angle, we can provide a link from Boegerweb.com Incoming links from our long-established sites help give you a boost.
• Make adjustments to your page titles, URL's, and taxonomies as needed based on Analytics and Webmaster Tools.

Some sites become more successful at showing up quickly than others. We've had clients hit their targets while we were still in testing phase of their site! Others -- in very competitive keyword fields -- have taken 2 or 3 months to start climbing the ranks of Google. Our sites do tend to climb the rankings of Yahoo! and Bing more quickly than Google (and we are not sure why.)
