      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:

        1. AJAX - Googlebot will not read any calls through AJAX. If you can load your link through an external call, it would be completely hidden.
        2. 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.
        3. 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.

            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?

            Links from new sites with no link juice

            Hi Guys, Do backlinks from a bunch of new sites pass any value to our site?  I've heard a lot from some "SEO experts" say that it is an effective link building strategy to build a bunch of new sites and link them to our main site.  I highly doubt that... To me, a new site is a new site, which means it won't have any backlinks in the beginning (most likely), so a backlink from this site won't pass too much link juice. Right? In my humble opinion  this is not a good strategy any more...if you build new sites for the sake of getting links. This is just wrong. But, if you do have some unique content and you want to share with others on that particular topic, then you can definitely create a blog and write content and start getting links. And over time, the domain authority will increase,  then a backlink from this site will become more valuable? I am not a SEO expert myself, so I am eager to hear your thoughts. Thanks.

            Site wide footer links vs. single link for websites we design

            I’ve been running a web design business for the past 5 years, 90% or more of the websites we build have a “web design by” link in the footer which links back to us using just our brand name or the full “web design by brand name” anchor text. I’m fully aware that site-wide footer links arent doing me much good in terms of SEO, but what Im curious to know is could they be hurting me? More specifically I’m wondering if I should do anything about the existing links or change my ways for all new projects, currently we’re still rolling them out with the site-wide footer links. I know that all other things being equal (1 link from 10 domains > 10 links from 1 domain) but is (1 link from 10 domains > 100 links from 10 domains)? I’ve got a lot of branded anchor text, which balances out my exact match and partial match keyword anchors from other link building nicely. Another thing to consider is that we host many of our clients which means there are quite a few on the same server with a shared IP. Should I? 1.) Go back into as many of the sites as I can and remove the link from all pages except the home page or a decent PA sub page- keeping a single link from the domain. 2.) Leave all the old stuff alone but start using the single link method on new sites. 3.) Scratch the site credit and just insert an exact-match anchor link in the body of the home page and hide with with CSS like my top competitor seems to be doing quite successfully. (kidding of course.... but my competitor really is doing this.)

            Is linking to search results bad for SEO?

            If we have pages on our site that link to search results is that a bad thing? Should we set the links to "nofollow"?
