Free web hosters
Free web hosting services can help to lower costs and technical barriers for webmasters, enabling new site owners easily create their own websites. Unfortunately, spammers often take advantage of these services to quickly and inexpensively create dozens or hundreds of sites that violate our quality guidelines and add little or no value to the web.Google makes a strong effort to take action only against individual spammy pages or sites. However, in some cases, when the spammers have pretty much taken over much or all of the free web hosting service, we may take action on how the free hosting service as a whole appears in search results in order to prevent spam from being shown to our users.
If you have a free hosting service, here are some ways to reduce or prevent spam:
Tell users that you don’t allow spam on your service
Publish a clear abuse policy and communicate it to your users, for example during the sign-up process.
Block automated account creation
Monitor your service for abuse
- Keep an eye on your webserver log files for sudden traffic spikes, especially for newly created sites.
- Monitor your free web hosting service for phishing and malware-infected pages. For example, you can use the Google Safe Browsing API to regularly test URLs from your service, or sign up for Safe Browsing alerts.
- Come up with a few sanity checks. For example, if you’re running a local Polish free web hosting service, what are the odds of thousands of new and legitimate sites in Japanese being created overnight on your service? A number of tools are available to detect the language of newly created sites—for example language detection libraries or the Google Translate API v2.
Identify spammy accounts
Keep a record of signups and try to identify typical spam patterns, such as:
- Form completion time
- Number of requests sent from the same IP address range
- User-agents used during signup
- User names or other form-submitted values chosen during signup.
