If you don't already have a Webmaster Tools account, add your site to Google Webmaster Tools. Make sure to add and verify all your sites, including subdomains. You should do this using the same Google Account you use for Custom Search.
Before requesting indexing of URLs in a Sitemap, check the following:
- Only Sitemaps submitted by a verified site owner are eligible for indexing. If you don't already have a Webmaster Tools account, add your site to Google Webmaster Tools. Make sure to add and verify all your sites, including subdomains. You should do this using the same Google Account you use for Custom Search. Alternatively, another site owner can add you as an owner.
- Create an XML Sitemap listing the pages you want Google to index on demand. In its simplest form, a Sitemap is a list of URLs on your site, although you can also use Sitemaps to give search engines additional information about your content. You must be a verified owner of all the sites and URLs listed in your Sitemap. You can submit multiple Sitemaps using Webmaster Tools, but all the URLs you want indexed immediately must be listed in a single Sitemap. Create a Sitemap.
- Upload your Sitemap to your server and submit it using Webmaster Tools. You can also submit using robots.txt and ping, but submitting using Webmaster Tools gives you access to Google diagnostic data, which can be very useful in troubleshooting problems.
You can ask Google to crawl a specific page or Sitemap to discover links to other pages on the same domain. All new pages on the same domain as the specified page or Sitemap will be added to the index, and will be crawled and indexed. In addition, Google will periodically revisit this page or Sitemap to discover and crawl new links.
Request ongoing indexing of content linked from a specific URL:
- On the Custom Search home page, click the search engine you want.
- Click Setup, and then click the Indexing tab.
- In the Index Now section, click URLs in a Sitemap. If the Sitemap you want is listed, select it. If not, type the URL to the Sitemap in the New Sitemap section.
- Click Index now.
Each URL Google discovers and crawls in this way counts against your indexing quota. If you exceed your quota, Custom Search won't index discovered URLs until quota is freed up.
