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?

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 Navigation Bar have an effect on the link juice and the number of internal links?
Hi Moz community, I am getting the "Avoid Too Many Internal Links" error from Moz for most of my pages and Google declared the max number as 100 internal links. However, most of my pages can't have internal links less than 100, since it is a commercial website and there are many categories that I have to show to my visitors by using the drop down navigation bar. Without counting the links in the navigation bar, the number of internal links is below 100. I am wondering if the navigation bar links affect the link juice and counted as internal links by Google. The Same question also applies to the links in the footer. Additionally, how about the products? I have hundreds of products in the category pages and even though I use pagination I still have many links in the category pages (probably more than 100 without even counting the navigation bar links). Does Google count the product links as internal links and how about the effect on the link juice? Here is the website if you want to take a look: http://www.goldstore.com.tr Thank you for your answers.

What's the best possible URL structure for a local search engine?
Hi Mozzers, I'm working at AskMe.com which is a local search engine in India i.e if you're standing somewhere & looking for the pizza joints nearby, we pick your current location and share the list of pizza outlets nearby along with ratings, reviews etc. about these outlets. Right now, our URL structure looks like www.askme.com/delhi/pizza-outlets for the city specific category pages (here, "Delhi" is the city name and "Pizza Outlets" is the category) and www.askme.com/delhi/pizza-outlets/in/saket for a category page in a particular area (here "Saket") in a city. The URL looks a little different if you're searching for something which is not a category (or not mapped to a category, in which case we 301 redirect you to the category page), it looks like www.askme.com/delhi/search/pizza-huts/in/saket if you're searching for pizza huts in Saket, Delhi as "pizza huts" is neither a category nor its mapped to any category. We're also dealing in ads & deals along with our very own e-commerce brand AskMeBazaar.com to make the better user experience and one stop shop for our customers. Now, we're working on URL restructure project and my question to you all SEO rockstars is, what can be the best possible URL structure we can have? Assume, we have kick-ass developers who can manage any given URL structure at backend.

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?

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?
