      I want to lead off by saying that I do not recommend trying this. My gut tells me that this is a bad idea, but I want to start a conversation about why.

      Since penguin a few weeks ago, one of the most common topics of conversation in almost every SEO/Webmaster forum is "how to remove spammy links". As Ryan Kent pointed out, it is almost impossible to remove all of these links, as these webmasters and previous link builders rarely respond. This is particularly concerning given that he also points out that Google is very adamant that ALL of these links are removed.

      After a handful of sleepless nights and some research, I found out that you can block traffic from specific referring sites using your.htaccess file. My thinking is that by blocking traffic from the domains with the spammy links, you could prevent Google from crawling from those sites to yours, thus indicating that you do not want to take credit for the link.

      I think there are two parts to the conversation...

      1. Would this work? Google would still see the link on the offending domain, but by blocking that domain are you preventing any strength or penalty associated with that domain from impacting your site?

      2. If for whatever reason this would nto work, would a tweak in the algorithm by Google to allow this practice be beneficial to both Google and the SEO community? This would certainly save those of us tasked with cleaning up previous work by shoddy link builders a lot of time and allow us to focus on what Google wants in creating high quality sites.

      Thoughts?

        I've thought about this idea to get rid of bad links from specific referrers.

        I agree with the comments Ian has made but when it is the homepage it's not always possible to follow those steps.  Has anyone else had any experience/information?

          Hi Ian,

          Thanks for the response. I agree with you that this feels wrong and I don't recommend anyone try this (unless you have a site that you don't mind using as a guinea pig).

          The problem is that, if this is your home page or a strong category page with many legitimate links, rankings, ect., it will be tough to abandon the page altogether.

          To follow up about the original idea, I have done some additional research and found a few mentions, though none of them exceptionally credible, of the fact that the Googlebot does not pass referrer data to the server. Can anyone confirm?

            Ooooh, that feels all wrong.

            Seems to me .htaccess would block visitors that you may want. And while Google may obey the directive, they may also misinterpret a referrer-specific directive as cloaking.

            If you want to get the same effect, here's what I'd do:

            1. Change the page to which the offending links point. Have it say "This page is gone, but you can get the information you want here" and make that a link to a new page.
            2. Set up your server to return a 410 code when folks visit that page.
            3. Set up a new page with the old page's content, so folks can click from the old to the new, but visiting bots and browsers get a 410 code and dump the page.

            That will get Google to de-index the page in a hurry.

            Another option: Simply add noindex, nofollow to the targeted page.

            But I like the 410 option, because that should break the authority flow and has the best chance of giving Google what it wants, short of removing the link.

              New Flurry of thousands of bad links from 3 Spammy websites. Disavow?

              I also discovered that a website www.prlog.ru put 32 links to my website.  It is a russian site.  It has a 32% spam score. Is that high? I think I need to disavow. Another spammy website link has spam score of 16% with with several thousand links. I added one link to the site medexplorer.com 6 years ago and it was fine. Now it has thousands of links. Should I disavow all three?

              Site Footer Links Used for Keyword Spam

              I was on the phone with a proposed web relaunch firm for one of my clients listening to them talk about their deep SEO knowledge. I cannot believe that this wouldn’t be considered black-hat or at least very Spammy in which case a client could be in trouble. On this vendor’s site I notice that they stack the footer site map with about 50 links that are basically keywords they are trying to rank for. But here’s the kicker shown by way of example from one of the themes in the footer: 9 footer links:
              Top PR Firms
              Best PR Firms
              Leading PR Firms
              CyberSecurity PR Firms
              Cyber Security PR Firms
              Technology PR Firms
              PR Firm
              Government PR Firms
              Public Sector PR Firms Each link goes to a unique URL that is basically a knock-off of the homepage with a few words or at the most one sentences swapped out to include this footer link keyword phrase, sometimes there is a different title attribute but generally they are a close match to each other. The canonical for each page links back to itself. I simply can’t believe Google doesn’t consider this Spammy. Interested in your view.

              Dealing with links to your domain that the previous owner set up

              Hey everyone, I rebranded my company at the end of last year from a name that was fairly unique but sounded like I cleaned headstones instead of building websites. I opted for a name that I liked, it reflected my heritage - however it also seems to be quite common. Anyway, I registered the domain name as it was available as the previous owner's company had been wound up. It's only been in the last week or two where I've managed to have a website on that domain and I've been tracking it's progress through Moz, Google & Bing Webmaster tools. Both the webmaster tools are reporting back that my site triggers 404 errors for some specific links. However, I don't have or have never used those links before. I think the previous owner might have created the links before he went bust. My question is in two parts. The first part is how do I find out what websites are linking to me with these broken URL's, and the second is will these 404'ing links affect my SEO? Thanks!

              Should You Link Back from Client's Website?

              We had a discussion in the office today, about if it can help or hurt you to link back to your site from one that you optimize, host, or manage. A few ideas that were mentioned: HURT:
              1. The website is not directly related to your niche, therefore Google will treat it as a link exchange or spammy link.
              2. Links back to you are often not surrounded by related text about your services, and looks out of place to users and Search Engines. HELP:
              1. On good (higher PR, reputable domain) domains, a link back can add authority, even if the site is not directly related to your services.
              2. Allows high ranking sites to show users who the provider is, potentially creating a new client, and a followed incoming link on anchor text you can choose. So, what do you think? Test results would be appreciated, as we are trying to get real data. Benefits and cons if you have an opinion.

              Pages linked with Spam been 301 redirected to 404\. Is it ok

              Pl suggest, some pages having some spam links pointed to those pages are been redirected to 404 error page (through 301 redirect) - as removing them manually was not possible due to part of core component of cms and many other coding issue, the only way as advised by developer was making 301 redirect to 404 page. Does by redirecting these pages to 404 page using 301 redirect, will nullify all negative or spam links pointing to them and eventually will remove the resulting spam impact on the site too. Many Thanks

              Off-page SEO and link building

              Hi everyone! I work for a marketing company; for one of our clients' sites, we are working with an independent SEO consultant for on-page help (it's a large site) as well as off-page SEO. Following a meeting with the consultant, I had a few red flags with his off-page practices – however, I'm not sure if I'm just inexperienced and this is just "how it works" or if we should shy away from these methods. He plans to: guest blog do press release marketing comment on blogs He does not plan to consult with us in advance regarding the content that is produced, or where it is posted. In addition, he doesn't plan on producing a report of what was posted where. When I asked  about these things, he told me they haven't encountered any problems before. I'm not saying it was spam-my, but I'm more not sure if these methods are leaning in the direction of "growing out of date," or the direction of "black-hat, run away, dude." Any thoughts on this would be crazy appreciated! Thanks, Casey

              Partners and Customers logo listing and links

              We have just created a program where we list the customers that use our software and a link to their websites on a new "Customers" page. We expect to have upwards of 100 logos with links back to their sites.  I want to be sure this isn't bordering on gray or black hat link building. I think it is okay since they are actual users of our software.  But there is still that slight doubt. Along these same lines, would you recommend adding a nofollow or noindex tag? Thanks for your help.
