Why are Seemingly Randomly Generated URLs Appearing as Errors in Google Webmaster Tools?
-
I've been confused by some URLs that are showing up as errors in our GWT account. They seem to just be randomly generated alphanumeric strings that Google is reporting as 404 errors. The pages do 404 because nothing ever existed there or was linked to. Here are some examples that are just off of our root domain:
/JEzjLs2wBR0D6wILPy0RCkM/WFRnUK9JrDyRoVCnR8=
/MevaBpcKoXnbHJpoTI5P42QPmQpjEPBlYffwY8Mc5I=
/YAKM15iU846X/ymikGEPsdq 26PUoIYSwfb8 FBh34=
I haven't been able to track down these character strings in any internet index or anywhere in our source code so I have no idea why Google is reporting them.
We've been pretty vigilant lately about duplicate content and thin content issues and my concern is that there are an unspecified number of urls like this that Google thinks exist but don't really.
Has anyone else seen GWT reporting errors like this for their site? Does anyone have any clue why Google would report them as errors?
-
Glad to hear you located the root cause of the issue.
-
Update: I think I found the source of the errors. We have a form submission box on every page of our site and there are random alphanumeric strings that are unique to every page that look like these urls that Google is reporting as errors. Maybe Google is trying to use our form submission tool.
It's still really odd that Google would think they are urls and report them as errors since they appear in an tag not an <a> tag</a>
<a>```
<input id="authenticity_token" name="authenticity_token" type="hidden" value="ElCkBCszxMddaqVyVIx+flkzRlM9xb7mHb3cFISlJvY=" /> -
The next step would be to check Google WMT > Diagnostics > Crawl errors > Not Found tab
Click the "Linked from Detected" text. That will show the source of the link.

That's not the case. We have an in house content system and no shopping cart. These urls return a 404 error and always have because they've never existed.
No crawlers have returned urls that look like this either. I can't get these urls to show up in Google's index either.

Hi Jimmy,
My bet is you are using a CMS or Shopping Cart on your site. The software is generating these seemingly random URLs, and the Google crawler is seeing them.
Crawlers don't move through your site the way people do. If you take your home page and right-click, then choose View Page Source, you will find many URLs. The crawler will then follow each and every URL throughout your site. The URLs you are seeing could be generated on any given page.
To track the issue, use the SEOmoz crawler on your site, then analyze the results. When you find these types of URLs, take note of the page they are located on.
Alternatively, you can contact your CMS or shopping cart's software developer and inquire about the URLs. If these URLs show a folder path before the random characters, that information can help track down which pages or software is generating these pages.

We have a client that wants to apply UTM URL tagging to track local organic traffic in Google Analytics. Is there any benefit in doing this?
One of our clients requested that we apply UTM URL tagging to better track organic traffic in Google Analytics. We found this to be an odd request because we are most familiar with UTM tracking for special campaigns (referral tracking, PPC, email tracking, etc). Is there any benefit of applying UTM tags to urls to analyze local organic traffic in Google Analytics? Are there any resources out there about this? Thanks!

Referral Traffic from Google
Hello, I have a question about my company's new website. I've worked in SEO and studied Google Analytics results for a few years now but have never really come across something like this. I started in this position in January of this year and when I started breaking down the traffic sources in Google Analytics, I noticed most of the traffic was coming from Google.com as a referral source. I had never seen Google.com as a referral source before so I looked into options for what it could be. It was not a paid ad and our organic traffic was coming through in Analytics, Before I could get any further, our new website was launched (we switched CRM's to WordPress) and the referral traffic from google went from 2,966 in January of 2015 to 22 in February 2015. for more comparison, in February of 2014, the referral traffic from Google was 2,496. I expected a drop when we switched CRM's but we correctly re-directed all pages and created a new sitemap and our organic traffic is up since the switch (not enough to cover drop in referral). I thought at first this had to do with our Google sellers account being de-activated when we made the switch, but I quickly fixed this over a month ago and no change. I'm wondering if anyone has ever seen Google.com come through as a referral source in Google Analytics and if they we're able to figure out what it actually was. This would be a great help! Thank you, Alex

Why google stubbornly keeps indexing my http urls instead of the https ones?
I moved everything to https in November, but there are plenty of pages which are still indexed by google as http instead of https, and I am wondering why. Example: http://www.gomme-auto.it/pneumatici/barum correctly redirect permanently to https://www.gomme-auto.it/pneumatici/barum Nevertheless if you search for pneumatici barum: https://www.google.it/search?q=pneumatici+barum&oq=pneumatici+barum The third organic result listed is still http. Since we moved to https google crawler visited that page tens of time, last one two days ago. But doesn't seems to care to update the protocol in google index. Anyone knows why? My concern is when I use API like semrush and ahrefs I have to do it twice to try both http and https, for a total of around 65k urls I waste a lot of my quota.

Link Research Tools
Is anyone else here a user of Link Research Tools? I recently completed a Link Detox for my sites. However, it is saying that links from high quality press release sites are deadly and should be removed. They are also saying the same about the links from the Yellow Pages. Obviously I know these tools are automated, but does anyone know why they are showing these links as 'deadly' and should be removed? I have tried contacting LRT about this issue but am yet to receive a reply.

Google as referring domain
Hi all, a colleague asked a question, which I could not answer (never even noticed this "problem") 😞 When we are logged into our GA account and go the referring domains section, we find Google. I always thought that these visitors came via Google Image Search, but not all of them do. Most of them come via "/imgres", but some come via "/" (always thought that "/" was the homepage?), "/url" and "//" Maybe I am just stupid, but honestly I could not explain what these strings mean... or how these visitors landed on our site... Can you help me???

Comparing % Change, Google Analytics
Hey Mozzers, Is there a simple way to compare the "% Change" in traffic when comparing two separate time periods in a single Google Analytics report? When comparing data from two separate time periods, an exported CSV doesn't include the % Change (booo!), and there's no option to sort by % Change within the GA report, essentially forcing you to scroll through all the results to pinpoint the major movers and shakers. I'm not averse to using spreadsheets to sort this data, but I'm thinking that I'd likely need a macro to make this work, something like this. However, none of the macros on that page are working (possibly because they were designed for a previous version of Analytics). All suggestions are appreciated. Thanks!
