Best way to block a search engine from crawling a link?
-
If we have one page on our site that is is only linked to by one other page, what is the best way to block crawler access to that page?
I know we could set the link to "nofollow" and that would prevent the crawler from passing any authority, and we can set the page to "noindex" to prevent it from appearing in search results, but what is the best way to prevent the crawler from accessing that one link?

Hi there,
I'm assuming you are trying to do pagerank sculpting (or something related..) - which was made a little more tough in recent years. I'll base my answer around this assumption, so feel free to correct me if this isn't the case.
There are several methods to make a link uncrawlable:
- AJAX - Googlebot will not read any calls through AJAX. If you can load your link through an external call, it would be completely hidden.
- Javascript - Obfuscate links with Javascript that masks the link. You can do any number of solutions here, including using tags with a title of your URL, which upon clicking, goes that that URL. Simple and effective.
- Redirects - I haven't tested this last idea, and it may not work. You might be able to redirect to another page in your website, which is then set to not be indexed. Then redirect to the intended page through a query string. In theory it should work, but obviously not as good as the previous methods I described.
Let me know if you have questions. I'd be glad to help further.
Cheers!

Noindex/nofollow should be good enough, but if you want to be sure it doesn't get indexed, you could can also include <meta name="robots" content="NOINDEX, NOFOLLOW"> in the head section of the page to be blocked. You can also exclude the page in your robots.txt file. </meta name="robots">
You can find a simple robots.txt generator in Google Webmaster Tools if you need to block particular pages or directories. The robots.txt file should be in the root directory of your site and look something like this:
User-agent: * Disallow: /file-you-want-to-hide.html
You can also request removal of specific URLs in Webmaster Tools if it has already been indexed.

How Many Links to Disavow at Once When Link Profile is Very Spammy?
We are using link detox (Link Research Tools) to evaluate our domain for bad links. We ran a Domain-wide Link Detox Risk report. The reports showed a "High Domain DETOX RISK" with the following results: -42% (292) of backlinks with a high or above average detox risk
Intermediate & Advanced SEO | | Kingalan1
-8% (52) of backlinks with an average of below above average detox risk
-12% (81) of backlinks with a low or very low detox risk
-38% (264) of backlinks were reported as disavowed. This look like a pretty bad link profile. Additionally, more than 500 of the 689 backlinks are "404 Not Found", "403 Forbidden", "410 Gone", "503 Service Unavailable". Is it safe to disavow these? Could Google be penalizing us for them> I would like to disavow the bad links, however my concern is that there are so few good links that removing bad links will kill link juice and really damage our ranking and traffic. The site still ranks for terms that are not very competitive. We receive about 230 organic visits a week. Assuming we need to disavow about 292 links, would it be safer to disavow 25 per month while we are building new links so we do not radically shift the link profile all at once? Also, many of the bad links are 404 errors or page not found errors. Would it be OK to run a disavow of these all at once? Any risk to that? Would we be better just to build links and leave the bad links ups? Alternatively, would disavowing the bad links potentially help our traffic? It just seems risky because the overwhelming majority of links are bad.0 -
What is best practice for "Sorting" URLs to prevent indexing and for best link juice ?
We are now introducing 5 links in all our category pages for different sorting options of category listings.
Intermediate & Advanced SEO | | lcourse
The site has about 100.000 pages and with this change the number of URLs may go up to over 350.000 pages.
Until now google is indexing well our site but I would like to prevent the "sorting URLS" leading to less complete crawling of our core pages, especially since we are planning further huge expansion of pages soon. Apart from blocking the paramter in the search console (which did not really work well for me in the past to prevent indexing) what do you suggest to minimize indexing of these URLs also taking into consideration link juice optimization? On a technical level the sorting is implemented in a way that the whole page is reloaded, for which may be better options as well.0 -

Do search engines crawl links on 404 pages?
I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl. Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

Link Research Tools - Detox Links
Hi, I was doing a little research on my link profile and came across a tool called "LinkRessearchTools.com". I bought a subscription and tried them out. Doing the report they advised a low risk but identified 78 Very High Risk to Deadly (are they venomous?) links, around 5% of total and advised removing them. They also advised of many suspicious and low risk links but these seem to be because they have no knowledge of them so default to a negative it seems. So before I do anything rash and start removing my Deadly links, I was wondering if anyone had a). used them and recommend them b). recommend detoxing removing the deadly links c). would there be any cases in which so called Deadly links being removed cause more problems than solve. Such as maintaining a normal looking profile as everyone would be likely to have bad links etc... (although my thinking may be out on that one...). What do you think? Adam

Outbound link to PDF vs outbound link to page
If you're trying to create a site which is an information hub, obviously linking out to authoritative sites is a good idea. However, does linking to a PDF have the same effect? e.g Linking to Google's SEO starter guide PDF, as opposed to linking to a google article on SEO. Thanks!

Best practice for removing indexed internal search pages from Google?
Hi Mozzers I know that it’s best practice to block Google from indexing internal search pages, but what’s best practice when “the damage is done”? I have a project where a substantial part of our visitors and income lands on an internal search page, because Google has indexed them (about 3 %). I would like to block Google from indexing the search pages via the meta noindex,follow tag because: Google Guidelines: “Use robots.txt to prevent crawling of search results pages or other auto-generated pages that don't add much value for users coming from search engines.” http://support.google.com/webmasters/bin/answer.py?hl=en&answer=35769 Bad user experience The search pages are (probably) stealing rankings from our real landing pages Webmaster Notification: “Googlebot found an extremely high number of URLs on your site” with links to our internal search results I want to use the meta tag to keep the link juice flowing. Do you recommend using the robots.txt instead? If yes, why? Should we just go dark on the internal search pages, or how shall we proceed with blocking them? I’m looking forward to your answer! Edit: Google have currently indexed several million of our internal search pages.
