Can competitors harm ranking
16 يناير 2009 
There's almost nothing a competitor can do to harm your ranking or have your site removed from our index. If you're concerned about another site linking to yours, we suggest contacting the webmaster of the site in question. Google aggregates and organizes information published on the web; we don't control the content of these pages.

Switching hosting companies or changing IP address
16 يناير 2009 
As long as your URL stays the same, your site's listing in Google shouldn't be affected if you switch hosting companies or change your IP address. We recommend migrating a site to a new IP address with the following steps: 1. Bring a copy of your site up at the new IP address. 2. Update your nameserver to point to the new IP address. 3. Once you see search engine spiders fetch pages from the new IP address (typically within 24-48 hours), it's safe to take down the copy of your site at the old IP address

AdWords or AdSense

AdWords or AdSense



Google's advertising programs are independent of our search results. Search results display on the left side of our results page; ads appear on the right and in the colored box at the top. Participation in an advertising program doesn't positively or negatively affect inclusion or ranking in the Google search results. Inclusion and ranking are free services; we don't accept payment to expedite inclusion or improve a site's ranking for particular keywords. Learn more about how Google ranks pages.

How often does Google crawl the web?

How often does Google crawl the web?



Google's spiders regularly crawl the web to rebuild our index. Crawls are based on many factors such as PageRank, links to a page, and crawling constraints such as the number of parameters in a URL. Any number of factors can affect the crawl frequency of individual sites.


Our crawl process is algorithmic; computer programs determine which sites to crawl, how often, and how many pages to fetch from each site. We don't accept payment to crawl a site more frequently. For tips on maintaining a crawler-friendly website, please visit our webmaster guidelines.

Site search box
16 يناير 2009 

Site search box



The site search box, which appears under the search results for some sites, lets you restrict your search to the selected site. For example, if the search box appears under the result for www.example.com, typing peanuts in the site search box will search the site www.example.com for the word "peanuts". It's the same as performing a site: search, like this: peanuts site:example.com.


The site search box makes it easier for users to refine their searches, and our experiments have found that this makes it faster to find the exact page they are looking for.


Webmasters don't have to optimize their sites to make the site search box appear. We don't display this box for all sites, but only when we determine - based on our user search data - that it would be useful to our users. As we refine this feature, the sites for which it appears may change.


You can also try other web search features supported by Google.
