500 error codes caused by W3 Total Cache plugin?
-
Hello Everyone,
I operate a site (http://www.nationalbankruptcyforum.com) that has been receiving 500 error codes in Webmaster Tools as of late. This morning, webmaster tools showed 129 500 crawling errors. I've included one of the URLs that contained an error message here: http://www.nationalbankruptcyforum.com/marriage-and-bankruptcy/do-my-wife-and-i-both-have-to-file-for-bankruptcy/
I've been getting these errors now for about 3 weeks and they've mostly been on obscure, strange URLs (lots of numbers etc.) however, this morning they started showing up on pages that will actually be trafficked by users. I'm really not sure where they're coming from, although I do believe it's a software issue as I've had my hosting company take a look to no avail.
I have had some development work done recently and am running the W3 Total Cache plugin (my site is built on WP). I also run the Yoast SEO plugin and rely on it to publish an XML sitemap among other things.
Anyone have any idea where these 500 errors originate from?
Thanks,
John

Dan, thanks for taking the time to look into this, I've sent your answer along to my developer, I'll update the thread if we find something that could help out other readers.

Hi John
I've checked this out a few times today, and tossed it around with a few other Moz people.
When I crawled the site earlier today with Screaming Frog, I got all the 500 errors you describe on the "normal" pages.
Now when I crawl the site I only get the "weird" pages with the unusual URLs.
We don't think this has to do with either Yoast of W3 Total Cache causing any of it. As far as what caused 500's on the "normal" pages, its hard to tell now. They loaded fine in my browser when I checked earlier.
But I strongly suspect maybe something going wrong in .htaccess for those stranger URLs.
Not sure why those URLs exist like that in the first place - they should all be "clean" whenever possible with the question marks etc in them. That'd be the first place I'd get straightened out. Check permalink settings or maybe a theme setting? Or did someone do something custom to the .htaccess file?
Get your URLs operating correctly. Then if the 500s still exist, you know its a different matter but at least you've narrowed it down and correct the URLs.
Hope this helps!

What could cause Google to not honor canonical URLs?
I have a strange situation on a website, when I do a Google query of site:example.com all the top indexed results appear to be queries that users can perform on the website. So any random term the user searches for on the website for some reason is causing the search result page to get indexed - like example.com/search/query/random-keywords However, the search results page has a canonical tag on it that points to example.com/search, but that doesn't seem to be doing anything. Any thoughts or ideas why this could be happening?

Content too buried in source code?
Our team is working on a refresh/redesign and am wondering if there's a quantifiable way of determining how high our meta data, H1 and paragraph should be in the source code. Or even whether I should be concerned with that. Our navigation will likely have dozens of links (we're going to keep it to under 100), and this doesn't even factor in the design elements. I am concerned about the content being buried. Are these the kind of concerns I should be having? Is there a measurable way to avoid it?

Google Crawler Error / restricting crawling
Hi On a Magento Instance we manage there is an advanced search. As part of the ongoing enhancement of the instance we altered the advance search options so there are less and more relevant. The issue is Google has crawled and catalogued the advanced search with the now removed options in the query string. Google keeps crawling these out of date advanced searches. These stale searches now create a 500 error. Currently Google is attempting to crawl these pages twice a day. I have implemented the following to stop this:- 1. Submitted requested the url be removed via Webmaster tools, selecting the directory option using uri: http://www.domian.com/catalogsearch/advanced/result/ 2. Added Disallow to robots.txt Disallow: /catalogsearch/advanced/result/* Disallow: /catalogsearch/advanced/result/ 3. Add rel="nofollow" to the links in the site linking to the advanced search. Below is a list of the links it is crawling or attempting to crawl, 12 links crawled twice a day each resulting in a 500 status. Can anything else be done? http://www.domain.com/catalogsearch/advanced/result/?bust_line=94&category=55&color_layered=128&csize[0]=0&fabric=92&inventry_status=97&length=0&price=5%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=115&category=55&color_layered=130&csize[0]=0&fabric=0&inventry_status=97&length=116&price=3%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=94&category=55&color_layered=126&csize[0]=0&fabric=92&inventry_status=97&length=0&price=5%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=137&csize[0]=0&fabric=93&inventry_status=96&length=0&price=8%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=142&csize[0]=0&fabric=93&inventry_status=96&length=0&price=4%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=137&csize[0]=0&fabric=93&inventry_status=96&length=0&price=5%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=142&csize[0]=0&fabric=93&inventry_status=96&length=0&price=5%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=135&csize[0]=0&fabric=93&inventry_status=96&length=0&price=5%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=128&csize[0]=0&fabric=93&inventry_status=96&length=0&price=5%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=127&csize[0]=0&fabric=93&inventry_status=96&length=0&price=4%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=127&csize[0]=0&fabric=93&inventry_status=96&length=0&price=3%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=128&csize[0]=0&fabric=93&inventry_status=96&length=0&price=10%2C10http://www.domain.com/catalogsearch/advanced/result/?bust_line=0&category=55&color_layered=122&csize[0]=0&fabric=93&inventry_status=96&length=0&price=8%2C10

Non-www to www code not working in htaccess
I use the same rewrite code on every site to consolidate the non-www and www versions. All sites in Joomla, linux hosting. Code is as follows: RewriteEngine On rewritecond %{http_host} ^site.com/ rewriteRule ^(.*) http://www.site.com/$1 [R=301,L] Immediately following this code, I also rewrite /index.php to /. Thing is, I can get index.php to rewrite correctly but the non-www won't rewrite to www. I use the same code on every site but for some reason it's not working here. Are there common issues that interfere with rewriting a non-www to www in htaccess that could be interfering with the code I'm using above?
