The changes are part of the company's efforts to minimize the impact of webspam
In 2010, Matt Cutts, head of Google's Webspam
team, said the company was taking social signals into account, but he had a different take earlier this year.
Matt Cutts, Head of Webspam
at Google, has been very clear on best practices here: "If you have alot of store or franchise locations, consider it a best practice to: 1.) Make a web page for each store that lists the store's address, phone number, business hours, etc.
Matt Cutts, Google's "principal engineer" and the head of its "webspam
team," has a blog in which he posts about these and other Google efforts, at http://www.mattcutts.com/blog.
The Chrome extension is the latest in a string of attempts to tackle the increasing concern over "webspam
," which Cutts defines as "junk you see in search results when websites try to cheat their way into higher positions in search results or otherwise violate search engine quality guidelines."
According to Google, the new changes are part of its efforts to minimize the impact of webspam
East Meadow, NY, October 17, 2014 --(PR.com)-- Spamdexed, the New York search engine penalty removal firm, announces the launch of their proprietary platform for submitting user-generated webspam reports to public listing services.
In commenting on their new webspam reporting tool, a spokesperson for Spamdexed said, "By providing every search engine user with access to our webspam reporting platform, we will be creating the most powerful community watch group in the world for identifying, reporting, researching and analyzing trending webspam techniques."
Responding to a comment from a user seeking advice with regards to potential penalties for linking too heavily to one site in a PR, Head of Webspam
at the search engine giant Cutts replied from his account “Note: I wouldn't expect links from press release web sites to benefit your rankings, however.”
"In the next few days, we're launching an important algorithm change targeted at webspam
. The change will decrease rankings for sites that we believe are violating Google's existing quality guidelines.
