      Reading these two articles made me feel sick. People are actually offering a service to de-rank a website.

      I could have swore I heard Matt Cutts say this was not possible, well the results are in.

      This really opens up a whole new can of worms for google.

      This is only going to get worse as news like this will spread like wildfire. In one sense, its good these people have done this to prove it to google its just a pity they did it on real business's that rely on traffic.

        Yeah I know, I read the full forum thread... Im not sure what you mean?

        Edit: Do you mean your post was not about the actual site it effected but more about Negative SEO? If so, we understand that, thats why we said it was scary. We were just pointing out the other issues in the forum thread.

          Its nothing got to do with the site in question. Its purely negative SEO. Read the case study about "Dan Thies" who says he is the SEO to Gurus and knows Matt Cutts on a personal basis. They targeted his website and got it off the ranks in about 1 week. He was ranked page 1 for "SEO" and "SEO services" now he is nowhere to be found.

            Oh absolutely, the backlinks generated from the story will make it worthwhile. Not sure if it was intended but it will benefit the site in the long run Im sure. Also, they did state a few times that his website was non-profit so it certainly wont hurt his lifestyle.

            Yeah I think that thread will be closely watched by big G... Probably not something to boast about on an online forum. However, he definitely knows his stuff so fair play to him - he has thought about it in great detail.

              On reflection, this is the kind of story that is going to gain some momentum in the business/marketing world and will probably generate a bucket load of nice authority links for the site...could this be a double bluff?

              either way mr negativeseo might have undone all his hard work simply by boasting about his exploits! I hope so.

                Definitely. I think that example was way OTT and not needed for most websites. I think it looks like it would be pretty easy for small businesses with smaller websites.

                Unfortunately there seems to be plenty of to55ers around. It worry's me that some people have no remorse... It could mean jobs lots and life's destroyed! Shame on Google!

                  Agreed Matt, that is scarey. though a years worth of work to deindex one competitor seems like a lot of hard work for little gain.

                  I'd rather spend the year doing something positive and not being a complete git.

                  After looking over the site in question, it may not be down to the negative SEO, theres an awful lot that could be improved on that site.

                    Scary stuff indeed...

                    I don't care how effective it may or may not be, I could never do this to a competitor... My motto would always be to beat them on merit and not cheating.

                    I have no doubt that this currently works but I also have no doubt that Google will close the loophole and instead of devaluing a website for "un-natural links" it will simply ignore the links - it is only a matter of time.

                    Lets cross our fingers that we don't have immoral competitors until that time comes.

                      Hi all, Found some websites stolen our content and using the same sentences in their website pages.  Does this content hurt our website rankings?  Their DA is low, still we are worried about the damage about this plagiarism. Thanks

                      Excluding Googlebot From AB Test - Acceptable Sample Size To Negate Cloaking Risk?

                      My company uses a proprietary AB testing platform. We are testing out an entirely new experience on our product pages, but it is not optimized for SEO. The testing framework will not show the challenger recipe to search bots. With that being said, to avoid any risks of cloaking, what is an acceptable sample size (or percentage) of traffic to funnel into this test?

                      Does type of hosting affect SEO rankings?

                      Hello, I was wondering if hosting on shared, versus VPS, versus dedicated ... matter at all in terms of the rankings of Web sites ... given that all other factors would be exactly equal. I know this is a big question with many variables, but mainly I am wondering if, for example, it is more the risk of resource usage which may take a site down if too much traffic and therefore make it un-crawlable if it happens at the moment that a bot is trying to index the site (factoring out the UX of a downed site). Any and all comments are greatly appreciated! Best regards,
                      Mark

                      I'm changing title tags and meta tags, url, will i loose my ranking?

                      Hi Guys QUESTION: I'm currently going through a re-design for my new website that was published in November 2014 - since launching we found there were many things we needed to change, our pages were content thin being one of the biggest. I had industry experts that came in and made comments on the title tags lacking relevance for eg: our title tag for our home page is currently "Psychic Advice" most ideal customers don't search "Psychic Advice" they search more like "Online Psychic Reading" or Psychic Readings" I noticed alot of my competitors also were using title tags such as Online Psychic Readings, Free Psychic Readings etc so it brings me to my question of "changing the title tags around.  The issue is, im ranking for two keywords in my industry, online psychics and online psychic readings in NZ. 1. Our home page and category pages are content thin.... so hoping that adding the changes will create perhaps some consistency also with the added unique and quality content. Here is the current website: zenory. co.nz and the new one is www.ew-zenory.herokuapp.com which is currently in development I have 3 top level domains com,com.au, and co.nz Is there anyone that can give me an idea if I were to change my home page title tag to **ZENORY | Online Psychic Readings | Live Psychic Phone and Chat ** If this will push my rankings down though this page will have alot more valuable content etc?  For obvious reasons im going to guess it will make drop, I'm wondering though if it is worth changing the title tags and meta descriptions around or leaving it as is if its already doing well? How much of a difference do title tags and meta descriptions really make? Any insight into this would be great! Thanks

                      Sitelinks Search Box impact for SEO

                      I am wondering how the relatively new sitelinks search box impacts the SEO rankings for a specific site or keyword combination - do you guys have any experience or bechmarks on this? Obviously it should help on getting more real estate on the SERP page (due to adding the search box), but do you also get extra goodwill and improved SERP position from adding it? Also, is the impact different on different type of terms, let's say single brand or category term such as "Bestbuy" (or "coupon") or a combination term "Bestbuy Apple" (or "Dixons coupon")? Thanks in advance!

                      Hi, Our IP was recently blacklisted - we had a malicious script sending out bulk mail in a Joomla installation. Does it hurt our SEO if we have a domain hosted on that IP? Any solid evidence? Thanks.

                      Recovering From Black Hat SEO Tactics

                      A client recently engaged my service to deliver foundational white hat SEO. Upon site audit, I discovered a tremendous amount of black hat SEO tactics employed by their former SEO company. I'm concerned that the efforts of the old company, including forum spamming, irrelevant backlink development, exploiting code vulnerabilities on BB's and other messy practices, could negatively influence the target site's campaigns for years to come. The site owner handed over hundreds of pages of paperwork from the old company detailing their black hat SEO efforts. The sheer amount of data is insurmountable. I took just one week of reports and tracked back the links to find that 10% of the accounts were banned, 20% tagged as abusive, some of the sites were shut down completely, WOT reports of abusive practices and mentions on BB control programs of blacklisting for the site. My question is simple. How does one mitigate the negative effects of old black hat SEO efforts and move forward with white hat solutions when faced with hundreds of hours of black gunk to clean up. Is there a clean way to eliminate the old efforts without contacting every site administrator and requesting removal of content/profiles? This seems daunting, but my client is a wonderful person who got in over her head, paying for a service that she did not understand. I'd really like to help her succeed. Craig Cook

                      Interesting case of IP-wide Google Penalty, what is the most likely cause?

                      Dear SEOMOZ Community, Our portfolio of around 15 internationalized web pages has received a significant, as it seems IP-wide, Google penalty starting November 2010 and have yet to recover from it. We have undergone many measure to lift the penalty including reconsideration requests wo/ luck and am now hoping the SEOMoz community can give us some further tips. We are very interested in the community's help and judgement what else we can try to uplift the penalty. As quick background information, The sites in question offers sports results data and is translated for several languages. Each market, equals language, has its own tld domain using the central keyword, e.g. <keyword_spanish>.es <keyword_german>.de <keyword_us>.com</keyword_us></keyword_german></keyword_spanish> The content is highly targeted around the market, which means there are no duplicate content pages across the domains, all copy is translated, content reprioritized etc. however the core results content in the body of the pages obviously needs to stay to 80% the same A SEO agency of ours has been using semi-automated LinkBuilding tools in mid of 2010 to acquire link partnerships There are some promotional one-way links to sports-betting and casino positioned on the page The external linking structure of the pages is very keyword and main-page focused, i.e. 90% of the external links link to the front page with one particular keyword All sites have a strong domain authority and have been running under the same owner for over 5 years As mentioned, we have experienced dramatic ranking losses across all our properties starting in November 2010. The applied penalties are indisputable given that rankings dropped for the main keywords in local Google search engines from position 3 to position 350 after the sites have been ranked in the top 10 for over 5 years. A screenshot of the ranking history for one particular domain is attached. The same behavior can be observed across domains. Our questions are: Is there something like an IP specific Google penalty that can apply to web properties across an IP or can we assume Google just picked all pages registered at Google Webmaster? What is the most likely cause for our penalty given the background information? Given the drops started already in November 2010 we doubt that the Panda updates had any correlation t this issue? What are the best ways to resolve our issues at this point? We have significant history data available such as tracking records etc. Our actions so far were reducing external links, on page links, and C-class internal links Are there any other factors/metrics we should look at to help troubleshooting the penalties? After all this time wo/ resolution, should we be moving on two new domains and forwarding all content as 301s to the new pages? Are the things we need to try first? Any help is greatly appreciated.
