      Hello

      I am getting loads of 404 reported in my Crawl report, all appended with void(0) at the end.  For example:

      http://lfs.org.uk/films-and-filmmakers/watch-our-films/1289/void(0)
      The site is running on Drupal 7,

      Has anyone come across this before?

      Kind Regards

      Moshe

        I think void(0) problem from WordPress theme if you use WordPress. Or, You can't setup perfectly javascript void(0) code on your template file.

        See the perfect javascript void(0) link examples on this page of wikihat => Kickass Torrents

        See the "click to open" button there.

            Hi Kane

            Many thanks for the links.  The Google forum link seems like to be the direction.  I am not the developer of the site, but will forward the link to them hoping they will help.  (been 3 years since site went live).

            Many thanks

            Moshe

              Hi Dimitri

              I am pretty sure that it is only the fact that something is producing links with void(0) at the end.  The link I used in my original post should actually be:

              http://lfs.org.uk/films-and-filmmakers/watch-our-films/1289/tongues

              The MOZ crawl report is saying that the above page is the Referrer to the

              http://lfs.org.uk/films-and-filmmakers/watch-our-films/1289/void(0)

              This repeats itself in many pages on the site.

              Many thanks
              Moshe

                Hi Moshen,

                My guess is that somewhere on the site, someone created a pop up window or another load effect and they used void(0) to create a link. The better practice is to create a normal link and control what happens when it's clicked by using Javascript. You could also add rel="nofollow" to those links, but it's less ideal than the first option.

                These explain the issue as well for additional reference:

                  Hi there.

                  It seems to be that there is something wrong with javascript. Because it seems like piece of JS code. However, even if i remove void part, the page still doesn't exist. You sure it's just "void(0)" problem?

                    WEbsite cannot be crawled

                    I have received the following message from MOZ on a few of our websites now Our crawler was not able to access the robots.txt file on your site. This often occurs because of a server error from the robots.txt. Although this may have been caused by a temporary outage, we recommend making sure your robots.txt file is accessible and that your network and server are working correctly. Typically errors like this should be investigated and fixed by the site webmaster. I have spoken with our webmaster and they have advised the below: The Robots.txt file is definitely there on all pages and Google is able to crawl for these files. Moz however is having some difficulty with finding the files when there is a particular redirect in place. For example, the page currently redirects from threecounties.co.uk/ to https://www.threecounties.co.uk/ and when this happens, the Moz crawler cannot find the robots.txt on the first URL and this generates the reports you have been receiving. From what I understand, this is a flaw with the Moz software and not something that we could fix form our end. _Going forward, something we could do is remove these rewrite rules to www., but these are useful redirects and removing them would likely have SEO implications. _ Has anyone else had this issue and is there anything we can do to rectify, or should we leave as is?

                    Woocommerce filter urls showing in crawl results, but not indexed?

                    I'm getting 100's of Duplicate Content warnings for a Woocommerce store I have. The urls are 
                     etc These don't seem to be indexed in google, and the canonical is for the shop base url. These seem to be simply urls generated by Woocommerce filters. Is this simply a false alarm from Moz crawl?

                    How to Fix 404 Errors

                    Hey Moz'ers - I just added a new site to my Moz Pro account and when I got the crawl report back there was a ton of 404 errors (see attached). I realize the best way to fix these is to manually go through every single error and see what the issue is... I just don't have time right now, and I don't have a team member that can jump on this either, but realize this will be a huge boost to this client if/when I get these resolved... So my question is: Is there a quicker way to get these resolved? Is there an outsourcing company that can fix my clients errors correctly? Thanks for the help in advance:) wBhzEeV

                    Crawlers crawl weird long urls

                    I did a crawl start for the first time and i get many errors, but the weird fact is that the crawler tracks duplicate long, not existing urls. For example (to be clear): there is a page: www.website.com/dogs/dog.html but then it is continuing crawling:
                    www.website.com/dogs/dog.html
                    www.website.com/dogs/dogs/dog.html
                    www.website.com/dogs/dogs/dogs/dog.html
                    www.website.com/dogs/dogs/dogs/dogs/dog.html
                    www.website.com/dogs/dogs/dogs/dogs/dogs/dog.html what can I do about this? Screaming Frog gave me the same issue, so I know it's something with my website

                    Problem crawling a website with age verification page.

                    Hy every1, Need your help very urgent. I need to crawl a website that first has a page where you need to put your age for verification and after that you are redirected to the website. My problem is that SEOmoz, crawls only that first page, not the whole website. How can I crawl the whole website?, do you need me to upload a link to the website? Thank you very much Catalin

                    Site Explorer - No Data Available for this URL

                    Hi All I have just joined on the trial offer, im not sure if i can afford the monthly payments, but im hoping SEOmoz will show me that i also cannot afford to be without it! In my proses of learning this site and flicking through each section to see what things do. However when i enter my URL into Site Explorer i get the following message "No Data Available for this URL" My site should be crawl-able, so how do i get to see data for my site/s. I wont post my URL here, as the site has a slightly adult theme.
                    If anyone could confirm if i can post "slightly adult" sites. Best Regards
                    Jon

                    Use of the tilde in URLs

                    I just signed up for SEOMoz and sent my site through the first crawl. I use the tilde in my rewritten URLs. This threw my entire site into the Notice section 301 (permanent redirect) since each page redirects to the exact URL with the ~, not the %7e. I find conflicting information on the web - you can use the tilde in more recent coding guidelines where you couldn't in the old. It would be a huge thing to change every page in my site to use an underscore instead of a tilde int he URL. If Google is like SEOMoz and is 301 redirecting every page on the site, then I'll do it, but is it just an SEOMoz thing? I ran my site through Firebug and and all my pages show the 200 response header, not the 301 redirect. Thanks for any help you can provide.
