salam every one, this is a topic from google web master centrale blog:
Webmaster level: Advanced

Today we’re introducing a tool that enables you to disavow links to your site. If you’ve been notified of a manual spam action based on “unnatural links” pointing to your site, this tool can help you address the issue. If you haven’t gotten this notification, this tool generally isn’t something you need to worry about.

First, a quick refresher. Links are one of the most well-known signals we use to order search results. By looking at the links between pages, we can get a sense of which pages are reputable and important, and thus more likely to be relevant to our users. This is the basis of PageRank, which is one of more than 200 signals we rely on to determine rankings. Since PageRank is so well-known, it’s also a target for spammers, and we fight linkspam constantly with algorithms and by taking manual action.

If you’ve ever been caught up in linkspam, you may have seen a message in Webmaster Tools about “unnatural links” pointing to your site. We send you this message when we see evidence of paid links, link exchanges, or other link schemes that violate our quality guidelines. If you get this message, we recommend that you remove from the web as many spammy or low-quality links to your site as possible. This is the best approach because it addresses the problem at the root. By removing the bad links directly, you’re helping to prevent Google (and other search engines) from taking action again in the future. You’re also helping to protect your site’s image, since people will no longer find spammy links pointing to your site on the web and jump to conclusions about your website or business.

If you’ve done as much as you can to remove the problematic links, and there are still some links you just can’t seem to get down, that’s a good time to visit our new Disavow links page. When you arrive, you’ll first select your site.


You’ll then be prompted to upload a file containing the links you want to disavow.


The format is straightforward. All you need is a plain text file with one URL per line. An excerpt of a valid file might look like the following:

# Contacted owner of spamdomain1.com on 7/1/2012 to

# ask for link removal but got no response
domain:spamdomain1.com
# Owner of spamdomain2.com removed most links, but missed these
http://www.spamdomain2.com/contentA.html
http://www.spamdomain2.com/contentB.html
http://www.spamdomain2.com/contentC.html

In this example, lines that begin with a pound sign (#) are considered comments and Google ignores them. The “domain:” keyword indicates that you’d like to disavow links from all pages on a particular site (in this case, “spamdomain1.com”). You can also request to disavow links on specific pages (in this case, three individual pages on spamdomain2.com). We currently support one disavowal file per site and the file is shared among site owners in Webmaster Tools. If you want to update the file, you’ll need to download the existing file, modify it, and upload the new one. The file size limit is 2MB.

One great place to start looking for bad links is the “Links to Your Site” feature in Webmaster Tools. From the homepage, select the site you want, navigate to Traffic > Links to Your Site > Who links the most > More, then click one of the download buttons. This file lists pages that link to your site. If you click “Download latest links,” you’ll see dates as well. This can be a great place to start your investigation, but be sure you don’t upload the entire list of links to your site -- you don’t want to disavow all your links!

To learn more about the feature, check out our Help Center, and we’d welcome your comments and questions in our forum. You’ll also find a video about the tool and a quick Q&A below.




We would reiterate that we built this tool for advanced webmasters only. We don't recommend using this tool unless you are sure that you need to disavow some links to your site and you know exactly what you're doing.

Q: Will most sites need to use this tool?
A: No. The vast, vast majority of sites do not need to use this tool in any way. If you’re not sure what the tool does or whether you need to use it, you probably shouldn’t use it.

Q: If I disavow links, what exactly does that do? Does Google definitely ignore them?
A: This tool allows you to indicate to Google which links you would like to disavow, and Google will typically ignore those links. Much like with rel=”canonical”, this is a strong suggestion rather than a directive—Google reserves the right to trust our own judgment for corner cases, for example—but we will typically use that indication from you when we assess links.

Q: How soon after I upload a file will the links be ignored?
A: We need to recrawl and reindex the URLs you disavowed before your disavowals go into effect, which can take multiple weeks.

Q: Can this tool be used if I'm worried about "negative SEO"?
A: The primary purpose of this tool is to help clean up if you've hired a bad SEO or made mistakes in your own link-building. If you know of bad link-building done on your behalf (e.g., paid posts or paid links that pass PageRank), we recommend that you contact the sites that link to you and try to get links taken off the public web first. You’re also helping to protect your site’s image, since people will no longer find spammy links and jump to conclusions about your website or business. If, despite your best efforts, you're unable to get a few backlinks taken down, that's a good time to use the Disavow Links tool.

In general, Google works hard to prevent other webmasters from being able to harm your ranking. However, if you're worried that some backlinks might be affecting your site's reputation, you can use the Disavow Links tool to indicate to Google that those links should be ignored. Again, we build our algorithms with an eye to preventing negative SEO, so the vast majority of webmasters don't need to worry about negative SEO at all.

Q: I didn’t create many of the links I’m seeing. Do I still have to do the work to clean up these links?
A: Typically not. Google normally gives links appropriate weight, and under normal circumstances you don't need to give Google any additional information about your links. A typical use case for this tool is if you've done link building that violates our quality guidelines, Google has sent you a warning about unnatural links, and despite your best efforts there are some links that you still can't get taken down.

Q: I uploaded some good links. How can I undo uploading links by mistake?
A: To modify which links you would like to ignore, download the current file of disavowed links, change it to include only links you would like to ignore, and then re-upload the file. Please allow time for the new file to propagate through our crawling/indexing system, which can take several weeks.

Q: Should I create a links file as a preventative measure even if I haven’t gotten a notification about unnatural links to my site?
A: If your site was affected by the Penguin algorithm update and you believe it might be because you built spammy or low-quality links to your site, you may want to look at your site's backlinks and disavow links that are the result of link schemes that violate Google's guidelines.

Q: If I upload a file, do I still need to file a reconsideration request?
A: Yes, if you’ve received notice that you have a manual action on your site. The purpose of the Disavow Links tool is to tell Google which links you would like ignored. If you’ve received a message about a manual action on your site, you should clean things up as much as you can (which includes taking down any spammy links you have built on the web). Once you've gotten as many spammy links taken down from the web as possible, you can use the Disavow Links tool to indicate to Google which leftover links you weren't able to take down. Wait for some time to let the disavowed links make their way into our system. Finally, submit a reconsideration request so the manual webspam team can check whether your site is now within Google's quality guidelines, and if so, remove any manual actions from your site.

Q: Do I need to disavow links from example.com and example.co.uk if they're the same company?
A: Yes. If you want to disavow links from multiple domains, you'll need to add an entry for each domain.

Q: What about www.example.com vs. example.com (without the "www")?
A: Technically these are different URLs. The disavow links feature tries to be granular. If content that you want to disavow occurs on multiple URLs on a site, you should disavow each URL that has the link that you want to disavow. You can always disavow an entire domain, of course.

Q: Can I disavow something.example.com to ignore only links from that subdomain?
A: For the most part, yes. For most well-known freehosts (e.g. wordpress.com, blogspot.com, tumblr.com, and many others), disavowing "domain:something.example.com" will disavow links only from that subdomain. If a freehost is very new or rare, we may interpret this as a request to disavow all links from the entire domain. But if you list a subdomain, most of the time we will be able to ignore links only from that subdomain.

from web contents: A new tool to disavow links 2013

salam every one, this is a topic from google web master centrale blog: Webmaster level: All



This week we launched an update to sitelinks to improve the organization and quality of our search results. Sitelinks are the two columns of links that appear under some search results and ads that help users easily navigate deeper into the site. Sitelinks haven’t changed fundamentally: they’re still generated and ranked algorithmically based on the link structure of your site, and they’ll only appear if useful for a particular query.





Sitelinks before today’s changes


Here’s how we’ve improved sitelinks with today’s launch:

  • Visibility. The links have been boosted to full-sized text, and augmented with a green URL and one line of text snippet, much like regular search results. This increases the prominence of both the individual sitelinks and the top site overall, making them easier to find.


  • Flexibility. Until now, each site had a fixed list of sitelinks that would either all appear or not appear; there was no query-specific ranking of the links. With today’s launch, sitelink selection and ranking can change from query to query, allowing more optimized results. In addition, the maximum number of sitelinks that can appear for a site has been raised from eight to 12, and the number shown also varies by query.


  • Clarity. Previously, pages from your site could either appear in the sitelinks, in the regular results, or both. Now we’re making the separation between the top domain and other domains a bit clearer. If sitelinks appear for the top result, then the rest of the results below them will be from other domains. One exception to this is if the top result for a query is a subpart of a domain. For instance, the query [the met exhibitions] has www.metmuseum.org/special/ as the top result, and its sitelinks are all from within the www.metmuseum.org/special section of the site. However, the rest of the results may be from other parts of the metmuseum.org domain, like store.metmuseum.org or blog.metmuseum.org/alexandermcqueen/about.


  • Quality. These user-visible changes are accompanied by quality improvements behind the scenes. The core improvement is that we’ve combined the signals we use for sitelinks generation and ranking -- like the link structure of your site -- with our more traditional ranking system, creating a better, unified algorithm. From a ranking perspective, there’s really no separation between “regular” results and sitelinks anymore.


Sitelinks after today’s changes


These changes are also reflected in Webmaster Tools, where you can manage the sitelinks that appear for your site. You can now suggest a demotion to a sitelink if it’s inappropriate or incorrect, and the algorithms will take these demotions into account when showing and ranking the links (although removal is not guaranteed). Since sitelinks can vary over time and by query, it no longer makes sense to select from a set list of links -- now, you can suggest a demotion of any URL for any parent page. Up to 100 demotions will be allowed per site. Finally, all current sitelink blocks in Webmaster Tools will automatically be converted to the demotions system. More information can be found in our Webmaster Tools Help Center.



It’s also worth mentioning a few things that haven’t changed. One-line sitelinks, where sitelinks can appear as a row of links on multiple results, and sitelinks on ads aren’t affected. Existing best practices for the link structure of your site are still relevant today, both for generating good quality sitelinks and to make it easier for your visitors. And, as always, you can raise any questions or comments in our Webmaster Help Forum.

salam every one, this is a topic from google web master centrale blog:
Webmaster Level: All

You may be familiar with sitelinks, the links that show up underneath the first search result and which lead to specific pages deeper within the site. Sitelinks enable users to jump directly to important parts of a site, which is often useful for large, complex websites. Sitelinks have the additional advantage of giving users an overview of a website's content by highlighting some of the popular parts of the site. For webmasters, sitelinks are also beneficial because they help to expose parts of your site that users may not know about. For instance, a search for NASA provides links to a gallery of images, a page about Space Shuttle and ISS missions, and so on:


Until now, sitelinks have only ever appeared on the first search result, and so at most one site could have sitelinks per query. We're now launching an expansion of sitelinks: a single row of links can now appear for results that didn't show sitelinks before, even for results that aren't in the first position. This means multiple results on one query can now have sitelinks. Up to four sitelinks can show up right above the page URL, instead of the usual two columns below the URL of the first result. Here's an example where the first three results each have one-line sitelinks:


These one-line sitelinks have many of the same benefits as the full two-column sitelinks, but on a smaller scale: they show users some relevant sub-pages in the site and give an idea of what the site is about. Comparing the sitelinks that appear for each result can even illustrate the difference between the sites. Just like regular sitelinks, one-line sitelinks are generated algorithmically and the decisions on when to show them and which links to display are entirely based on the expected benefit to users.

For webmasters, this new feature means it's possible that your site will start showing sitelinks for a number of queries where it previously didn't. We expect this will increase the visibility of and traffic to your site, while also improving the experience of users. If, however, you absolutely would prefer not to have a particular sitelink show up, remember that you can always block a page from appearing as a sitelink for 90 days through Webmaster Tools. In fact, as part of our ongoing efforts at improving the Webmaster Tools experience, we're speeding up our response time to blocked pages, so you should see a blocked page get dropped as a sitelink even faster than before. If you need a quick refresher on how to use the sitelink blocking tool, take a look at this previous blog post. Currently you can only block sitelinks on your site's home page, but we're working on expanding this capability so you'll soon be able to remove them from any other page as well.

We hope you find these improvements to sitelinks and Webmaster Tools helpful for both your site and your visitors!
