Find all external 404 errors/links?
-
Hi All,
We have recently discovered a site was linking to our site but it was linking to an incorrect url, resulting in a 404 error. We had only found this by pure chance and wondered if there was a tool out there that will tell us when a site is linking to an incorrect url on our site?
Thanks

If you dont have access to the logs that could be an issue - not really any automated tools out there as it would need to crawl every website and find 404 errors.
I haven't tried this - so its just an idea. Go into GSC download all the links pointing to your site (and from places like Moz, Ahrefs, Majestic) and then chuck that list of urls into Screaming Frog or URL Profiler and look at external links and see if any are returning a 404. Not sure if this would work - its just an idea.
Thanks
Andy

Great, will take a look. Maybe run a trial to see if it does exactly what I need

Thanks for the info!

Good idea!
Although some of our clients that we do SEO for aren't hosting their websites on our server and we don't have access to their server logs etc.
Was hoping for an automated dashboard like MOZ/Screaming Frog/ or A hrefs as mentioned above. Due to the amount of clients we have, opening up and running through all there Log files could be time consuming.
Cheers for the info though, may come in use in the future, or to someone else reading this

Hi
The best way I have found is to look in your server logs, its the only true place to find out what Google is doing on your site.
Download the logs and look at all the 404 errors - quite simple and depending on size of your logs can take you around 5 minutes worth a work - the longer time period you can analyse in your logs the better.
Thanks

Hi David.
Ahrefs.com offers that service: broken links.
Another way to do that search could be this: Downloading the historic backlinks list and with a mass checker, check where do they point nowdays. I've used GScraper and its option to crawl outbound links.
Best Luck.
GR.

Sitemap error in Webmaster tools - 409 error (conflict)
Hey guys, I'm getting this weird error when I submit my sitemap to Google. It says I'm getting a 409 error in my post-sitemap.xml file (https://cleargear.com/post-sitemap.xml). But when I check it, it looks totally fine. I am using YoastSEO to generate the sitemap.xml file. Has anyone else experienced this? Is this a big deal? If so, Does anyone know how to fix? Thanks EwTswL4

How can I stop a tracking link from being indexed while still passing link equity?
I have a marketing campaign landing page and it uses a tracking URL to track clicks. The tracking links look something like this: http://this-is-the-origin-url.com/clkn/http/destination-url.com/ The problem is that Google is indexing these links as pages in the SERPs. Of course when they get indexed and then clicked, they show a 400 error because the /clkn/ link doesn't represent an actual page with content on it. The tracking link is set up to instantly 301 redirect to http://destination-url.com. Right now my dev team has blocked these links from crawlers by adding  Disallow: /clkn/  in the robots.txt file, however, this blocks the flow of link equity to the destination page. How can I stop these links from being indexed without blocking the flow of link equity to the destination URL?

<sub>& <sup>tags, any SEO issues?</sup></sub>
Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub> Thanks.

404 error - but I can't find any broken links on the referrer pages
Hi, My crawl has diagnosed a client's site with eight 404 errors. In my CSV download of the crawl, I have checked the source code of the 'referrer' pages, but can't find where the link to the 404 error page is. Could there be another reason for getting 404 errors? Thanks for your help. Katharine.

Redirecting blog.<mydomain>.com to www.<mydomain>.com\blog</mydomain></mydomain>
This is more of a technical question than pure SEO per se, but I am guessing that some folks here may have covered this and so I would appreciate any questions. I am moving from a WordPress.com-based blog (hosted on WordPress) to a WordPress installation on my own server (as suggested by folks in another thread here). As part of this I want to move from the format blog.<mydomain>.com to www.mydomain.com\blog. I have installed WordPress on my server and have imported posts from the hosted site to my own server. How should I manage the transition from first format to the second? I have a bunch of links on Facebook, etc that refer to URLs of the blog..com format so it's important that I redirect.</mydomain> I am running DotNetNuke/WordPress on my own IIS/ASP.Net servers. Thanks. Mark
