      Hi,

      Does anyone know if search console errors showing as follows are damaging to serps:

      /xmlrpc.php is returning 405 error

      /wp-admin/admin-ajax.php is returning 400 error

      These errors seem to of coincided almost to the day that there was a ranking drop for the primary keyword from mid page 1 to bottom of page 2.

      No matter what I do I cannot seem to correct these errors.

      Any advice would be greatly appreciated.

      Thanks

        Both issues are on ALL WordPress sites.

        xmlrpc.php return 405 because it's work under HTTP POST but bot crawl under HTTP GET.
        And error 405 mean switch from GET to POST. But bot can't do that.

        admin-ajax.php return 400 because it's not designed for direct use. You must make call with some parameter and it will return some information.
        But as name says - it's responsible for AJAX calls and it's not for direct use that's why it return 400 when it's called w/o parameters.

        So - that issues are not related to your issue.
        For example mine WP sites also return same error codes to the bot.

          To answer your question: "Does anyone know if search console errors showing as follows are damaging to SERPS." - No, this would almost be impossible. The errors that you're mentioning are just two core pages of WordPress that cause some errors where the 400 error is actually supposed to happen as it's not a URL that is just accessible like this. It's a file that is being used to make AJAX requests.

          The fact that this potentially coincides with a uplift/drop in rankings is probably caused by something else.

            Hello there,

            Both of this error can be caused by either a corrupted file, which you can download a new one from WordPress and see if this fix the problem.

            If not I would suggest you start by turning off all your plugin one by one and see if there's some plugin that caused the conflict.

            Hope this helps.

              Unsolved Google Search Console Still Reporting Errors After Fixes

              google search console sitemaps 400 errors

              Hello, I'm working on a website that was too bloated with content. We deleted many pages and set up redirects to newer pages. We also resolved an unreasonable amount of 400 errors on the site. I also removed several ancient sitemaps that listed content deleted years ago that Google was crawling. According to Moz and Screaming Frog, these errors have been resolved. We've submitted the fixes for validation in GSC, but the validation repeatedly fails. What could be going on here? How can we resolve these error in GSC.

              GMB Bulk Upload Error

              Hello! I am continuing to have issues with the bulk upload option.Currently, there are 12 non-verified locations in a location group in my GMB account. I have approximately 6-8 more that need to be added to this group via bulk upload. When uploading the spreadsheet, I receive an error reading "You've exceeded the limit for the about of locations you can upload to Google My Business in a single day. Try again later." It seems to happen specifically to the locations that aren't in my GMB account already. The others, the ones already in the account, are fine and simply read "No updates" when the bulk upload sheet is read. Everything else is marked as an error. Why is it marking some listings as nonviable when they come in via the bulk verification spreadsheet, which has been downloaded directly from the links Google has provided, and filled in with the help of the sample and amenities list?How do we finish uploading all of the remaining locations?I have another group, separate group (same company, groups split into US and International) under my name that may also need a bulk upload - what can I do to avoid this error in the future? Can they still be bulk uploaded to my account after I upload the first location group's listings?If you could provide any guidance, I'd be very grateful.Thanks in advance!

              Desktop & Mobile XML Sitemap Submitted But Only Desktop Sitemap Indexed On Google Search Console

              Hi! The Problem We have submitted to GSC a sitemap index. Within that index there are 4 XML Sitemaps. Including one for the desktop site and one for the mobile site. The desktop sitemap has 3300 URLs, of which Google has indexed (according to GSC) 3,000 (approx). The mobile sitemap has 1,000 URLs of which Google has indexed 74 of them. The pages are crawlable, the site structure is logical. And performing a Landing Page URL search (showing only Google/Organic source/medium) on Google Analytics I can see that hundreds of those mobile URLs are being landed on. A search on mobile for a longtail keyword from a (randomly selected) page shows a result in the SERPs for the mobile page that judging by GSC has not been indexed. Could this be because we have recently added rel=alternate tags on our desktop pages (and of course corresponding canonical ones on mobile). Would Google then 'not index' rel=alternate page versions? Thanks for any input on this one. PmHmG

              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 🙂

              Duplicate content and 404 errors

              I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

              How is a dash or "-" handled by Google search?

              I am targeting the keyword AK-47 and it the  variants in search (AK47, AK-47, AK 47) .  How should I handle on page SEO?  Right now I have AK47 and AK-47 incorporated. So my questions is really do I need to account for the space or is Google handling a dash as a space? At a quick glance of the top 10 it seems the dash is handled as a space, but I just wanted to get a conformation from people much smarter then I at seomoz. Thanks, Jason
