Today, Matt Cutts (Head of Google Webspam team) announced improvements to Google’s spam reporting form, saying via Twitter: “We just released the biggest refresh of our spam report form in, oh, say 10 years”: http://t.co/ty2MxmN

There are a lot of forms for reporting various types of webspam to Google now. Hopefully these tools will help to reduce the amount of webspam out there, and with Google’s excellent track record, we should see some good results.

We’ll assume that any reports that are made receive human review before blacklisting/filtering, so that false reports (e.g. competitive harassment) are quickly culled. If your company experiences unjustified filtering (as judged by industry-sanctioned practices) by any of the new web filtering tools in practice today, however, we’d like to know about it. We, like most of you, would like to see spam filtering perfected to the point that true spam is filtered but legitimate email and web traffic is not filtered.

Browser Blacklists

The fact that you are reading this site indicates that you have either experienced a problem with, or know something about, email blacklists. But did you know that malware can be installed on your website that causes browsers to blacklist your website? It’s not always obvious when this malware is installed, but it could be costing your business money and reputation when it goes undetected.

Search engines and browsers, led by Google and Firefox, now regularly blacklist thousands of legitimate websites each day that get infected with malware. Sites that get blacklisted lose most of their traffic from Google and Firefox and incur significant revenue and brand losses.

As a result, it’s a good idea to check your site on a regular basis for browser blacklisting, in addition to email blacklisting.

2013 Update: We plan to post a tool to check for browser blacklisting in the near future.
