Free web hosting services can be great! Many of these services have helped to lower costs and technical barriers for webmasters and they continue to enable beginner webmasters to start their adventure on the web. Unfortunately, sometimes these lower barriers (meant to encourage less techy audiences) can attract some dodgy characters like spammers who look for cheap and easy ways to set up dozens or hundreds of sites that add little or no value to the web. When it comes to automatically generated sites, our stance remains the same: if the sites do not add sufficient value, we generally consider them as spam and take appropriate steps to protect our users from exposure to such sites in our natural search results.


If a free hosting service begins to show patterns of spam, we make a strong effort to be granular and tackle only spammy pages or sites. However, in some cases, when the spammers have pretty much taken over the free web hosting service or a large fraction of the service, we may be forced to take more decisive steps to protect our users and remove the entire free web hosting service from our search results. To prevent this from happening, we would like to help owners of free web hosting services by sharing what we think may help you save valuable resources like bandwidth and processing power, and also protect your hosting service from these spammers:

• Publish a clear abuse policy and communicate it to your users, for example during the sign-up process. This step will contribute to transparency on what you consider to be spammy activity.
• In your sign-up form, consider using CAPTCHAs or similar verification tools to only allow human submissions and prevent automated scripts from generating a bunch of sites on your hosting service. While these methods may not be 100% foolproof, they can help to keep a lot of the bad actors out.
• Try to monitor your free hosting service for other spam signals like redirections, large numbers of ad blocks, certain spammy keywords, large sections of escaped JavaScript code, etc. Using the site: operator query or Google Alerts may come in handy if you’re looking for a simple, cost efficient solution.
• Keep a record of signups and try to identify typical spam patterns like 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, etc. Again, these may not always be conclusive.
• Keep an eye on your webserver log files for sudden traffic spikes, especially when a newly-created site is receiving this traffic, and try to identify why you are spending more bandwidth and processing power.
• Try to 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 to receive alerts for your AS.
• 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? There’s a number of tools you may find useful for language detection of newly created sites, for example language detection libraries or the Google Translate API v2.

Last but not least, if you run a free web hosting service be sure to monitor your services for sudden activity spikes that may indicate a spam attack in progress.

For more tips on running a quality hosting service, have a look at our previous post. Lastly, be sure to sign up and verify your site in Google Webmaster Tools so we may be able to notify you when needed or if we see issues.

If you're a webmaster or site owner, you realize the importance of providing high quality search on your site so that users easily find the right information.

We just announced today that AdSense for Search is now powered by Custom Search. Custom Search (a Google-powered search box that you can install on your website in minutes) helps your users quickly find what they're looking for. As a webmaster, Custom Search gives you advanced customization options to improve the accuracy of your site's search results. You can also choose to monetize your traffic with ads tuned to the topic of your site. If you don't want ads, you can use Custom Search Business Edition.



Now, we're also looking to index more of your site's content for inclusion in your Custom Search Engine (CSE) used for search on your site. We figure out what sites and URLs are included in your CSE, and -- if you've provided Sitemaps for the relevant sites -- we use that information to create a more comprehensive experience for your site's visitors. You don't have to do anything specific, besides submitting a Sitemap (via Webmaster Tools) for your site if you haven't already done so. Note that this change will not result in more pages indexed on Google.com and your search rankings on Google.com won't change. However, you will be able to get much better results coverage in your CSE.

Custom Search is built on top of the Google index. This means that all pages that are available on Google.com are also available to your search engine. We're now maintaining a CSE-specific index in addition to the Google.com index for enhancing the performance of search on your site. If you submit a Sitemap, it's likely that we will crawl those pages and include them in the additional index we build.

In order for us to index these additional pages, our crawlers must be able to crawl them. Your Sitemap will also help us identify the URLs that are important. Please ensure you are not blocking us from crawling any pages you want indexed. Improved index coverage is not instantaneous, as it takes some time for the pages to be crawled and indexed.

So what are you waiting for? Submit your Sitemap!this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com

Here's the second of our video blog posts. Matt Cutts, the head of Google's webspam team, provides some useful tips on how to optimize the images you include on your site, and how simply providing useful, accurate information in your ALT attributes can make your photos and pictures more discoverable on the web. Ms Emmy Cutts also makes an appearance.



Like videos? Hate them? Have a great idea we should cover? Let us know what you think in our Webmaster Help Group.

Update: Some of you have asked about the difference between the "alt" and "title" attributes. According to the W3C recommendations, the "alt" attribute specifies an alternate text for user agents that cannot display images, forms or applets. The "title" attribute is a bit different: it "offers advisory information about the element for which it is set." As the Googlebot does not see the images directly, we generally concentrate on the information provided in the "alt" attribute. Feel free to supplement the "alt" attribute with "title" and other attributes if they provide value to your users!this is a topic published in 2013... to get contents for your blog or your forum, just contact me at: devnasser@gmail.com
