Can I Use Meta NoIndex to Block Unwanted Links?
-
I have a forum thread on my site that is completely user generated, not spammy at all, but it is attracting about 45 backlinks from really spammy sites. Usually when this happens, the thread is created by a spammer and I just 404 it. But in this instance, the thread is completely legit, and I wouldn't want to 404 it because users could find it useful.
If I add a meta noindex, nofollow tag to the header, will the spammy pagerank still be passed? How best can I protect myself from these low quality backlinks? I don't want to get slapped by Penguin!
**Note: I cannot find contact information from the spam sites and it's in a foreign language.

Thanks for responding. I think you're absolutely right, we need to take those precautions and then deal with the bad backlinks. I will try the disavow tool as well. Thanks!

Thank you for your response! I will try the disavow tool.

As LesleyPaone suggested below, ensure your post links are set to nofollow; this is especially sought after for spammers and bots.
I would not suggest using a noindex tag, unless you want your pages to be removed from the SERPs (which I don't think you do).
Don't be afraid to use the Disavow tool, but only use it on sites/pages that you identify as spam. The issue with Disavowing is that some users disavow an entire domain and the domain may not be spam related, thereby removing wanted links from a site's backlink profile.
If you know the site is spammy and do not want backlinks from that site, then feel secure disavowing the domain.

Hi Ray-pp,
In this instance, no, a bot is not creating spam on MY site. Someone is linking to my site from an external, spammy site. So yes, I am "wondering how to combat external forum threads that link back to your website, but are spammy." As you put it.
You mention using the Google disavow tool...but I have read that it can be dangerous to use. Would a case like this really warrant use of Google disavow? And back to my original question, can I use meta noindex, no follow to block bad link juice?

I help moderate a relatively busy forum, sever hundred thousand active users, let me share some of our insights.
It sounds like you have links in posts being followed, no follow all links in posts no matter who posts them. For footer signatures, make a threshold, say 25 posts before the user can have a footer signature. If you want to give people more incentive to post, have a do follow link in their profile after a certain threshold has been passed, like Moz does.
Fighting forum spam is a full time job almost, but it is easier to beat it in the beginning than just handle it as it comes in. Create a honey pot on your registration form and change it out weekly. Something like this could work, http://solutionfactor.net/blog/2014/02/01/honeypot-technique-fast-easy-spam-prevention/
As for the links on the other sites I would disavow them, but once you stop the spam, they should stop. What they are doing is called link laundering. They are placing a link in your forum, then they are using a service like fiverr or similar to build backlinks to the forum link. They do this in hopes to raise the authority of the forum post and in turn raise the authority of links pointing to their site. They are pretty insulated from penalties by doing this, but they risk you getting a penalty.

Hi TMI.com,
Are you saying that you have a forum where spam/bots create a forum thread to link back to their website? Which creates a number of spammy threads on your forum which you then have to remove?
If so, then you would first want to combat that spam through your Forum software. How can you create barriers for bots creating new threads?
-
Require someone to create an account and login prior to posting
-
Require threads with a link to go to admin moderation
-
Make it so only users with X Activity have the ability to post links (e.g. users who have previously posted 10 legit threads can enable posting links in forum threads)
-
Integrate a CAPTCHA when posting threads/comments
These are a few common strategies for preventing on-site forum spam.
If you're wondering how to combat external forum threads that link back to your website, but are spammy. Then identify those pages and use the Google Disavow Tool to distance your site from that spammy content. If you notice a domain being habitually offensive, you may want to disavow the entire domain for any future backlinks.

Link with Anchor to header of the page: Keyword is ranking
I saw something interesting this week. I am doing research and spec-ing out a content page we are creating and one of our competitors "office Depot" on their phone repair page create exact match keywords that lead to an anchor that took you to the header of that pages. They were ranking first for all of those keywords with little to no links Thier strategy is the more local long tail that includes "near me" Have you guys ever seen this
White Hat / Black Hat SEO | | uBreakiFix
this is the URL: https://www.officedepot.com/a/content/customer-service/samedayrepair/ They are ranking for these keywords ( Top 3 nationally ) iphone 6 repair near me iphone 7 repair near me I am assuming that this is both due to their PA and DA authority shifting the authority to itself, but it does not make sense how they are lacking in a lot of SEO low-hanging fruits like H1/H2 keyword saturation, URL, Title Tag within this content page....Anyone up for discussing this?0 -

Diminishing Returns for Links to an Unrelated Page
Suppose I have a new website about cars and I had created a page about something completely not-related - like cupcakes. However, I found that it was very easy to get high quality sites to link to the cupcakes page where as it was very difficult to get people to link to the homepage about cars. If my goal is to increase the SEO for the homepage (which again is related to cars), is there a point where additional high quality links to my cupcakes page is not useful for it anymore? What if I created another page - about frosted cupcakes - which was also easy to get high quality links to?

Domain authority - Low quality links
I have a question I hope people can help me on. it is my intention for my next project to focus on domain authority, and a small number of high quality links. I have a couple of scenarios I would appreciate some advice on: 1. Can lower quality links lower domain authority? 2. Would you avoid links from low quality sites no matter what \ what domain authority levels should you avoid links from. 3. Should I be looking at link profiles of the sites I get links from. Does it matter if a site I get a link from has 1000's of spammy links (i.e. something to look out for when doing guest blogging). 4. Should I avoid directories no matter what, or is high pr \ domain authority directories ok to use, if I end up on a page of other relevant directory submissions related to my niche. Essentially, my aim is to have high quality links, but equally, there are some decent sites on the fringes that I will need to consider (based on a competitors link profile I researches).

Hiding content or links in responsive design
Hi, I found a lot of information about responsive design and SEO, mostly theories no real experiment and I'd like to find a clear answer if someone tested that. Google says:
White Hat / Black Hat SEO | | NurunMTL
Sites that use responsive web design, i.e. sites that serve all devices on the same set of URLs, with each URL serving the same HTML to all devices and using just CSS to change how the page is rendered on the device
https://developers.google.com/webmasters/smartphone-sites/details For usability reasons sometimes you need to hide content or links completely (not accessible at all by the visitor) on your page for small resolutions (mobile) using CSS ("visibility:hidden" or "display:none") Is this counted as hidden content and could penalize your site or not? What do you guys do when you create responsive design websites? Thanks! GaB0 -
Rel Noindex Nofollow tag vs meta noindex nofollow robots
Hi Mozzers I have a bit of thing I was pondering about this morning and would love to hear your opinion on it. So we had a bit of an issue on our client's website in the beginning of the year. I tried to find a way around it by using wild cards in my robots.txt but because different search engines treat wild cards differently it dint work out so well and only some search engines understood what I was trying to do. so here goes, I had a parameter on a big amount of URLs on the website with ?filter being pushed from the database we make use of filters on the site to filter out content for users to find what they are looking for much easier, concluding to database driven ?filter URLs (those ugly &^% URLs we all hate so much*. So what we looking to do is implementing nofollow noindex on all the internal links pointing to it the ?filter parameter URLs, however my SEO sense is telling me that the noindex nofollow should rather be on the individual ?filter parameter URL's metadata robots instead of all the internal links pointing the parameter URLs. Am I right in thinking this way? (reason why we want to put it on the internal links atm is because the of the development company states that they don't have control over the metadata of these database driven parameter URLs) If I am not mistaken noindex nofollow on the internal links could be seen as page rank sculpting where as onpage meta robots noindex nofolow is more of a comand like your robots.txt Anyone tested this before or have some more knowledge on the small detail of noindex nofollow? PS: canonical tags is also not doable at this point because we still in the process of cleaning out all the parameter URLs so +- 70% of the URLs doesn't have an SEO friendly URL yet to be canonicalized to. PSS: another reason why this needs looking at is because search engines won't be able to make an interpretation of these pages (until they have been cleaned up and fleshed out with unique content) which could result in bad ranking of the pages which could conclude to my users not being satisfied, so over and above the SEO factor, usability of the site is being looked at here as well, I don't want my users to land on these pages atm. If they navigate to it via the filters then awesome because they are defining what they are looking for with the filters. Would love to hear your thoughts on this. Thanks, Chris Captivate.

Is a directory like this white hat? Useful?
This is one of my competitor's backlinks: http://bit.ly/mMPhmn Prices for inclusion on this page go from $50 for 6 months to $300 for a permanent listing. Do most of you guys do paid directories like this for your SEO Clients? My gut is telling me to run away...but I don't want to miss a good opportunity if I should be taking it.
