Deny visitors by referrer in .htaccess to clean up spammy links?
-
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...
-
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?
-
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:
- 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.
- Set up your server to return a 410 code when folks visit that page.
- 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.

Do links from subdomains pass the authority and link juice of main domain ?
Hi, There is a subdomain with a root domain's DA 90. I can earn a backlink from that subdomain. This subdomain is fresh with no traffic yet. Do I get the ranking boost and authority from the subdomain? Example: I can earn a do-follow link from **https://what-is-crm.netlify.app/ **but not from https://netlify.app

Spam Score & Redirecting Inbound Links
Hi, I recently downloaded a spreadsheet of inbound links to my client sites and am trying to 301 redirect the ones that are formatted incorrectly or just bad links in general (they all link to the site domain, but they used to have differently formatted urls on their old site, or the link URL in general has strange stuff on it). My question is, should I even bother redirecting these links if their spam score is a little high (i.e. 20-40%)? it already links to the existing domain, just with a differently formatted URL. I just want to make sure it goes to a valid URL on the site, but I don't want to redirect to a valid URL if it's going to harm the client's SEO. Also not sure what to do about the links with the --% spam score. I really appreciate any input as I don't have a lot of experience with how to deal with spammy links.

Traffic exchange referral URL's
We have a client who once per month is being hit by easyihts4u.com and it is creating huge increases in their referrals. All the hits go to one page specifically. From the research we have done, this site and others like it, are not spam bots. We cannot understand how they choose sites to target and what good it does for them, or our client to have hits all on one days to one page? We created a filter in analytics to create what we think is a more accurate reflection of traffic. Should be block them at the server level as well?

Suspicious external links to site have 302 redirects
Hi, I have been asked to look at a site where I suspect some questionable SEO work, particularly link building. The site does seem to be performing very poorly in Google since January 2014, although there are no messages in WMT. Using WMT, OPenSiteExplorer, Majestic & NetPeak, I have analysed inbound links and found a group of links which although are listed in WMT, etc appear to 302 redirect to a directory in China (therefore the actual linking domain is not visible). It looks like a crude type of link farm, but I cant understand why they would use 302s not 301s. The domains are not visible due to redirects. Should I request a disavow or ignore? The linking domains are listed below: http://www.basalts.cn/

Disavow links leading to 404
Looking at the link profile anchor text of a site i'm working on new links keep popping up in the reports with let's say very distasteful anchor text. These links are obviously spam and link to old forum pages for the site that doesn't exist any more, so the majority seem to trigger the 404 page. I understand that the 404 page (404 header response) does not flow any link power, or damage, but given the nature and volume of the sites linking to the "domain" would it be a good idea to completely disassociate and disavow these domains?

Should I Do a Social Bookmarking Campaign and a Tier 2 Linking?
I don't see anything bad in manually creating links on different (about 50) social bookmarking services. Is this method labeled as White Hat? I was wondering if it would be fine to create Tier 2 linking (probably blog comments) for indexing of the social bookmarking links? Please share your thoughts on the topic.

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.

Would linking out to a gambling/casino site, harm my site and the other sites it links out to?
I have been emailed asking if I sell links on one of my sites. The person wants to link out to slotsofvegas[dot]com or similar. Should I be concerned about linking out to this and does it reduce the link value to any of the other sites that the site links out to? Thanks, Mark
