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.

Best way to set up URL structure for reviews off of PDP pages.
We are adding existing customer reviews to Product Detail Pages pages. There are about 300 reviews per product so we're going to have to paginate reviews off of the PDP page. I'm wondering what the best url structure for reviews pages is to get the most seo benefit. For example, would it be something like this? site.com/category/product/reviews/page-1 or something that used parameters, such as: site.com/reviews?product=a Also, what is the best way to show that the internal link on the PDP page to "All Reviews" is a higher priority link than the other links on the page?

Google Image Search - Is there a way to influence the related icons at the top of the image search results?
Google recently added related icons at the top of the image search results page. Some of the icons may be unrelated to the search. Are there any best practices to influence what is positioned in the related image icons section? Thank you.

New Subdomain & Best Way To Index
We have an ecommerce site, we'll say at https://example.com. We have created a series of brand new landing pages, mainly for PPC and Social at https://sub.example.com, but would also like for these to get indexed. These are built on Unbounce so there is an easy option to simply uncheck the box that says "block page from search engines", however I am trying to speed up this process but also do this the best/correct way. I've read a lot about how we should build landing pages as a sub-directory, but one of the main issues we are dealing with is long page load time on https://example.com, so I wanted a kind of fresh start. I was thinking a potential solution to index these quickly/correctly was to make a redirect such as https://example.com/forward-1 -> https:sub.example.com/forward-1 then submit https://example.com/forward-1 to Search Console but I am not sure if that will even work. Another possible solution was to put some of the subdomain links accessed on the root domain say right on the pages or in the navigation. Also, will I definitely be hurt by 'starting over' with a new website? Even though my MozBar on my subdomain https://sub.example.com has the same domain authority (DA) as the root domain https://example.com? Recommendations and steps to be taken are welcome!

What's the best way to noindex pages but still keep backlinks equity?
Hello everyone, Maybe it is a stupid question, but I ask to the experts... What's the best way to noindex pages but still keep backlinks equity from those noindexed pages? For example, let's say I have many pages that look similar to a "main" page which I solely want to appear on Google, so I want to noindex all pages with the exception of that "main" page... but, what if I also want to transfer any possible link equity present on the noindexed pages to the main page? The only solution I have thought is to add a canonical tag pointing to the main page on those noindexed pages... but will that work or cause wreak havoc in some way?

Does Disavowing Links Negate Anchor Text, or Just Negates Link Juice
I'm not so sure that disavowing links also discounts the anchor texts from those links. Because nofollow links absolutely still pass anchor text values. And disavowing links is supposed to be akin to nofollowing the links. I wonder because there's a potential client I'm working on an RFP for and they have tons of spammy directory links all using keyword rich anchor texts and they lost 98% of their traffic in Pengiun 1.0 and haven't recovered. I want to know what I'm getting into. And if I just disavow those links, I'm thinking that it won't help the anchor text ratio issues. Can anyone confirm?

Do 404 pages pass link juice? And best practices...
Last year Google said bad links to 404 pages wouldn't hurt your site. Could that still be the case in light of recent Google updates to try and combat spammy links and negative SEO? Can links to 404 pages benefit a website and pass link juice? I'd assume at the very least that any link juice will pass through links FROM the 404 page? Many websites have great 404 pages that get linked to: http://www.opensiteexplorer.org/links?site=http%3A%2F%2Fretardzone.com%2F404 - that was the first of four I checked from the "60 Really Cool...404 Pages" that actually returned the 404 HTTP Status! So apologies if you find the word 'retard' offensive. According to Open Site Explorer it has a decent Page Authority and number of backlinks - but it doesn't show in Google's SERPs. I'd never do it, but if you have a particularly well-linked to 404 page, is there an argument for giving it 200 OK Status? Finally, what are the best practices regarding 404s and address bar links? For example, if
Intermediate & Advanced SEO | | Alex-Harford
www.examplesite.com/3rwdfs returns a 404 error, should I make that redirect to
www.examplesite.com/404 or leave it as is? Redirecting to www.examplesite.com/404 might not be user-friendly as people won't be able to correct the URL in the address bar. But if I have a great 404 page that people link to, I don't want links going to loads of random pages do I? Is either way considered best practice? If I did a 301 redirect I guess it would send the wrong signal to the crawlers? Should I use a 302 redirect, or even a 304 Not Modified redirect?1 -
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.
