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.

SEO advice on ecommerce url structure where categories contain "/c/"
Hi! We use Hybris as plattform and I would like input on which url to choose. We must keep "/c/" before the actual category. c stands for category. I.e. this current url format will be shortened and cleaned:

https://www.granngarden.se/Sortiment/Husdjur/Hund/Hundfoder-%26-Hundmat/c/hundfoder To either: a.Â
https://www.granngarden.se/husdjur/hund/hundfoder/c/hundfoder b.
https://www.granngarden.se/husdjur/hund/c/hundfoder (hundfoder means dogfood) The question is whether we should keep the duplicated category name (hundfoder) before the "/c/" or not. Will there be SEO disadvantages by removing the duplicate "hundfoder" before the "/c/"? I prefer the shorter version ofc, but do not want to jeopardize any SEO rankings or send confusing signals to search engines or customers due to the "/c/" breaking up the url breadcrumb. What do you guys say and prefer from the above alternatives? Thanks /Hampus0 -
Hosting images externally
In these days of CDNs does it matter for SEO whether images (and PDFs etc.) are hosted off-site? Does it make a difference if images hosted on Flickr, photobucket etc. Thanks

/~username
Hello, The utility on this site that crawls your site and highlights what it sees as potential problems reported an issue with /~username access seeing it as duplicate content i.e. mydomain.com/file.htm is the same as mydomain.com~/username/file.htm so I went to my server hosts and they disabled it using mod_userdir but GWT now gives loads of 404 errors. Have I gone about this the wrong way or was it not really a problem in the first place or have I fixed something that wasn't broken and made things worse? Thanks, Ian

How does Google find /feed/ at the end of all pages on my site?
Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?

Does the Referral Traffic from a Link Influence the SEO Value of that Link?
If a link exists, and nobody clicks on it, could it still be valuable for SEO? Say I have 1000 links on 500 sites with Domain Authority ranging from 35 to 80. Let's pretend that 900 of those links generate referral traffic. Let's assume that the remaining 100 links are spread between 10 domains of the 500, but nobody ever clicks on them. Are they still valuable? Should an SEO seek to earn more links like those, even though they don't earn referral traffic? Does Google take referral data into account in evaluating links? 5343313-zelda-rogers-albums-zelda-pictures-duh-what-else-would-they-be-picture3672t-link-looks-so-lonely.jpg Sad%20little%20link.jpg
