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 "Prune" bad content from large sites?
I am in process of pruning my sites for low quality/thin content. The issue is that I have multiple sites with 40k + pages and need a more efficient way of finding the low quality content than looking at each page individually. Is there an ideal way to find the pages that are worth no indexing that will speed up the process but not potentially harm any valuable pages? Current plan of action is to pull data from analytics and if the url hasn't brought any traffic in the last 12 months then it is safe to assume it is a page that is not beneficial to the site. My concern is that some of these pages might have links pointing to them and I want to make sure we don't lose that link juice. But, assuming we just no index the pages we should still have the authority pass along...and in theory, the pages that haven't brought any traffic to the site in a year probably don't have much authority to begin with. Recommendations on best way to prune content on sites with hundreds of thousands of pages efficiently? Also, is there a benefit to no indexing the pages vs deleting them? What is the preferred method, and why?

Crawled page count in Search console
Hi Guys, I'm working on a project (premium-hookahs.nl) where I stumble upon a situation I can’t address. Attached is a screenshot of the crawled pages in Search Console. History: Doing to technical difficulties this webshop didn’t always no index filterpages resulting in thousands of duplicated pages. In reality this webshops has less than 1000 individual pages. At this point we took the following steps to result this: Noindex filterpages. Exclude those filterspages in Search Console and robots.txt. Canonical the filterpages to the relevant categoriepages. This however didn’t result in Google crawling less pages. Although the implementation wasn’t always sound (technical problems during updates) I’m sure this setup has been the same for the last two weeks. Personally I expected a drop of crawled pages but they are still sky high. Can’t imagine Google visits this site 40 times a day. To complicate the situation: We’re running an experiment to gain positions on around 250 long term searches. A few filters will be indexed (size, color, number of hoses and flavors) and three of them can be combined. This results in around 250 extra pages. Meta titles, descriptions, h1 and texts are unique as well. Questions: - Excluding in robots.txt should result in Google not crawling those pages right? - Is this number of crawled pages normal for a website with around 1000 unique pages? - What am I missing?

Sitemaps during a migration - which is the best way of dealing with them?
Many SEOs I know simply upload the new sitemap once the new site is launched - some keep the old site's URLs on the new sitemap (for a while) to facilitate the migration - others upload both the old and the new website together, to support the migration. Which is the best way to proceed? Thanks, Luke

My website (non-adult) is not appearing in Google search results when i have safe search settings on. How can i fix this?
Hi, I have this issue where my website does not appear in Google search results when i have the safe search settings on. If i turn the safe search settings off, my site appears no problem. I'm guessing Google is categorizing my website as adult, which it definitely is not. Has anyone had this issue before? Or does anyone know how to resolve this issue? Any help would be much appreciated. Thanks

Do links to PDF's on my site pass "link juice"?
Hi, I have recently started a project on one of my sites, working with a branch of the U.S. government, where I will be hosting and publishing some of their PDF documents for free for people to use. The great SEO side of this is that they link to my site. The thing is, they are linking directly to the PDF files themselves, not the page with the link to the PDF files. So my question is, does that give me any SEO benefit? While the PDF is hosted on my site, there are no links in it that would allow a spider to start from the PDF and crawl the rest of my site. So do I get any benefit from these great links? If not, does anybody have any suggestions on how I could get credit for them. Keep in mind that editing the PDF's are not allowed by the government. Thanks.

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?
