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.

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.

[Very Urgent] More 100 "/search/adult-site-keywords" Crawl errors under Search Console
I just opened my G Search Console and was shocked to see more than 150 Not Found errors under Crawl errors. Mine is a Wordpress site (it's consistently updated too): Here's how they show up: Example 1: URL: www.example.com/search/adult-site-keyword/page2.html/feed/rss2 Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword/page2.html Example 2 (this surprised me the most when I looked at the linked from data): URL: www.example.com/search/adult-site-keyword-2.html/page/3/ Linked From: www.example.com/search/adult-site-keyword-2.html/page/2/ (this is showing as if it's from our own site) http://a-spammy-adult-site.com/search/adult-site-keyword-2.html Example 3: URL: www.example.com/search/adult-site-keyword-3.html Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword-3.html How do I address this issue?

If I nofollow outbound external links to minimize link juice loss > is it a good/bad thing?
OK, imagine you have a blog, and you want to make each blog post authoritative so you link out to authority relevant websites for reference. In this case it is two external links per blog post, one to an authority website for reference and one to flickr for photo credit. And one internal link to another part of the website like the buy-now page or a related internal blog post. Now tell me if this is a good or bad idea. What if you nofollow the external links and leave the internal link untouched so all internal links are dofollow. The thinking is this minimizes loss of link juice from external links and keeps it flowing through internal links to pages within the website. Would it be a good idea to lay off the nofollow tag and leave all as do follow? or would this be a good way to link out to authority sites but keep the link juice internal? Your thoughts are welcome. Thanks.

Best way to remove full demo (staging server) website from Google index
I've recently taken over an in-house role at a property auction company, they have a main site on the top-level domain (TLD) and 400+ agency sub domains! company.com agency1.company.com agency2.company.com... I recently found that the web development team have a demo domain per site, which is found on a subdomain of the original domain - mirroring the site. The problem is that they have all been found and indexed by Google: demo.company.com demo.agency1.company.com demo.agency2.company.com... Obviously this is a problem as it is duplicate content and so on, so my question is... what is the best way to remove the demo domain / sub domains from Google's index? We are taking action to add a noindex tag into the header (of all pages) on the individual domains but this isn't going to get it removed any time soon! Or is it? I was also going to add a robots.txt file into the root of each domain, just as a precaution! Within this file I had intended to disallow all. The final course of action (which I'm holding off in the hope someone comes up with a better solution) is to add each demo domain / sub domain into Google Webmaster and remove the URLs individually. Or would it be better to go down the canonical route?

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!

Increasing Internal Links But Avoiding a Link Farm
I'm looking to create a page about Widgets and all of the more specific names for Widgets we sell: ABC Brand Widgets, XYZ Brand Widgets, Big Widgets, Small Widgets, Green Widgets, Blue Widgets, etc. I'd like my Widget page to give a brief explanation about each kind of Widget with a link deeper into my site that gives more detail and allows you to purchase. The problem is I have a lot of Widgets and this could get messy: ABC Green Widgets, Small XYZ Widgets, many combinations. I can see my Widget page teetering on being a link farm if I start throwing in all of these combos. So where should I stop? How much do I do? I've read more than 100 links on a page being considered a link farm, is that a hardline number or a general guideline?

Do search engines understand special/foreign characters?
We carry a few brands that have special foreign characters, e.g., Kühl, Lolë, but do search engines recognize special unicode characters? Obviously we would want to spend more energy optimizing keywords that potential customers can type with a keyboard, but is it worthwhile to throw in some encoded keywords and anchor text for people that copy-paste these words into a search? Do search engines typically equate special characters to their closest English equivalent, or are "Kuhl", "Kühl" and "Kühl" three entirely different terms?
