There are two possible explanations. First, check the limits of the package you have purchased. Certain limits apply to our packages.
If that is not the reason, it may be that our "Spider" can't find all of the pages on your site. In many cases, this can occur if there are portions of your site not linked in some way to your home page.
Since our Spider works primarily by "crawling" from link to link on your site, unlinked pages are sometimes missed. To help us get a more comprehensive scan, you can place a "Sitemap" file on your site, which will tell our Spider where to look. For details on how to create this file, please visit http://www.sitemaps.org
