Do Ghost Traffic/Spam Referrals factor into rankings, or do they just affect the CTR and Bounce Rate in Analytics?
-
So, by now I'm sure everyone that pays attention to their Analytics/GWT's (or Search Console, now) has seen spam referral traffic and ghost traffic showing up (Ilovevitaly.com, simple-share-buttons.com, semalt.com, etc). Here is my question(s)... Does this factor into rankings in anyway? We all know that click through rate and bounce rate (might) send signals to the algorithm and signal a low quality site, which could affect rankings. I guess what I'm asking is are they getting any of that data from Analytics? Since ghost referral traffic never actually visits my site, how could it affect the CTR our Bounce Rate that the algorithm is seeing? I'm hoping that it only affects my Bounce/CTR in Analytics and I can just filter that stuff out with filters in Analytics and it won't ever affect my rankings. But.... since we don't know where exactly the algorithm is pulling data on CTR and bounce rate, I guess I'm just worried that having a large amount of this spam/ghost traffic that I see in analytics could be causing harm to my rankings.... Sorry, long winded way of saying... Should I pay attention to this traffic? Should I care about it? Will it harm my site or my rankings at all? And finally... when is google going to shut these open back doors in Analytics so that Vitaly and his ilk are shut down forever?

Hi seequs, to complement Cyrus answer, here is an explanation of Matt Cutts related to your question. https://www.youtube.com/watch?v=CgBw9tbAQhU. And if you think about it, it wouldn't be fair since not everyone uses Google Analytics.
About the spam harming your site, if we talk about ghost spam there is nothing to worry(except for your data of course) since there is not real interaction with the spam and any of your pages, it all happens in GA. On the other hand, Crawler Spam does access your site, and it uses your resources, although is nothing to be alarmed since visits from this type of spam are less frequent than ghosts.
If you want to fully block crawlers you can do it by adding some lines to your .htaccess file, like this
STOP REFERRER SPAM
RewriteCond %{HTTP_REFERER} semalt.com [NC,OR]
RewriteCond %{HTTP_REFERER} buttons-for-website.com [NC]
RewriteRule .* - [F]It seems that the problem with the spam is not that simple. For what I understand they are preparing a guide. In the meantime, if you are not already using a filter based on valid hostnames, I recommend you to do it, one filter, and you will forget about the ghost spam. You can find more information about this solution here
Hope it helps,

Short answer: no (or at least, very unlikely)
Google publicly states they don't pull data form inside GA, and realistically they don't need to. They are only concerned about the performance of their search results, and how that traffic responds to individual results. They also have no reason to lie about not using GA data, as there are so many other sources of information that are better.
"And finally... when is google going to shut these open back doors in Analytics so that Vitaly and his ilk are shut down forever?"
Great question! Hopefully soon.

Spam sites with low spam score?
Hello! I have a fair few links on some of the old SEO 'Directory' sites. I've got rid of all the obviously spammy ones - however there are a few that remain which have very low spam scores, and decent page authority, yet they are clearly just SEO directories - I can't believe they service any other purpose. Should we now just be getting rid of all links like this, or is it worth keeping if the domain authority is decent and spam score low? Thanks Sam

Advice needed! How to clear a website of a Wordpress Spam Link Injection Google penalty?
Hi Guys, I am currently working on website that has been penalised by Google for a spam link injection. The website was hacked and 17,000 hidden links were injected. All the links have been removed and the site has subsequently been redesigned and re-built. That was the easy part 🙂 The problems comes when I look on Webmaster. Google is showing 1000's of internal spam links to the homepage and other pages within the site. These pages do not actually exist as they were cleared along with all the other spam links. I do believe though this is causing problems with the websites rankings. Certain pages are not ranking on Google and the homepage keyword rankings are fluctuating massively. I have reviewed the website's external links and these are all fine. Does anyone have any experience of this and can provide any recommendations / advice for clearing the site from Google penalty? Thanks, Duncan

Pages mirrored on unknown websites (not just content, all the HTML)... blackhat I've never seen before.
Someone more expert than me could help... I am not a pro, just doing research on a website... Google Search Console shows many backlinks in pages under unknown domains... this pages are mirroring the pages of the linked website... clicking on a link on the mirror page leads to a spam page with link spam... The homepage of these unknown domain appear just fine... looks like that the domain is partially hijacked... WTF?! Have you ever seen something likes this? Can it be an outcome of a previous blackhat activity?

Black hat : raising CTR to have better rank in Google
We all know that Google uses click-through-rate (CTR) as one of it is ranking factor. I came up with an idea in my mind. I would like to see if someone saw this idea before or tried it. If you search in Google for the term "SEO" for example. You will see the moz.com website in rank 3. And if you checked the source code you will see that result 3 is linking to this url: https://www.google.com.sa/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&uact=8&ved=0CDMQFjAC&url=https%3A%2F%2Fmoz.com%2Fbeginners-guide-to-seo&ei=F-pPVaDZBoSp7Abo_IDYAg&usg=AFQjCNEwiTCgNNNWInUJNibqiJCnlqcYtw That url will redirect you to seomoz.com Ok, what if we use linkbucks.com or any other cheap targeted traffic network and have a campaign that sends traffic to the url that I show you. Will that count as traffic from Google so it will increase the CTR from Google?

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

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?

What are good sources to buy traffic and video views?
I am looking into buying traffic for a website and I'd like to know if anyone has had a positive experience doing so. What are the best companies that sell traffic? I also want to buy video views. This is a trickier question. I upload the videos to YouTube and use the embed code on my website. I want the paid video views on my site so I get the traffic and YT gets the video view. Any suggestions? Thanks
