When you remove pages from the web, they will naturally drop out of Google’s index as we crawl your site again and note the changes. To speed up the removal process, you can use the URL Removal Tool in Webmaster Tools to request removal of your page.
You can also remove URLs on the Indexing page of the Custom Search control panel.
Remove individual URLs
- On the Custom Search home page, click the search engine you want.
- Click Setup.
- In the Sites to search section, select the URL(s) you want to remove, and then click Delete.
Remove multiple URLs using a Sitemap
To urgently remove multiple URLs from your Custom Search results, you can add those URLs to a Sitemap, and use the expires tag to indicate that the page is no longer valid. Then, submit that Sitemap for on-demand indexing.
To request a removal of a URL from a site, you must have verified your ownership of that site in Webmaster Tools.
Here's a sample of a Sitemap entry for a URL that needs to be removed from the Custom Search index:
<?xml version="1.0" encoding="UTF-8"?>
<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9">
...
<url>
<loc>http://www.example.com/expired.html</loc>
<expires>2011-06-21</expires>
</url>
<url>
<loc>http://www.example.com/also_expired.html</loc>
<expires>2011-06-21T18:00:00+00:00</expires>
</url>
</urlset>
You can use up to 10% of your on-demand quota for URL removals.
