      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.

              Does anyone know the linking of hashtags on Wix sites does it negatively or positively impact SEO.  It is coming up as an error in site crawls 'Pages with 404 errors'  Anyone got any experience please? For example at the bottom of this blog post https://www.poppyandperle.com/post/face-painting-a-global-language the hashtags are linked, but they don't go to a page, they go to search results of all other blogs using that hashtag.  Seems a bit of a strange approach to me.

              Role of Robots.txt and Search Console parameters settings

              Hi, wondering if anyone can point me to resources or explain the difference between these two. If a site has url parameters disallowed in Robots.txt is it redundant to edit settings in Search Console parameters to anything other than "Let Googlebot Decide"?

              Errors In Search Console

              Hi All, I am hoping someone might be able to help with this. Last week one of my sites dropped from mid first day to bottom of page 1. We had not been link building as such and it only seems to of affected a single search term and the ranking page (which happens to be the home page). When I was going through everything I went to search console and in crawl errors there are 2 errors that showed up as detected 3 days before the drop. These are: wp-admin/admin-ajax.php showing as response code 400 and also xmlrpc.php showing as response code 405 robots.txt is as follows: user-agent: * disallow: /wp-admin/ allow: /wp-admin/admin-ajax.php Any help with what is wrong here and how to fix it would be greatly appreciated. Many Thanks

              Schema Markup Errors - Priority or Not?

              Greetings All... I've been digging through the search console on a few of my sites and I've been noticing quite a few structured data errors. Most of the errors are related to: hcard, hentry and hatom. Most of them are missing author & entry-title, while the other one is  missing: fn. I recently saw an article on SEL about Google's focus on spammy mark-up. The sites I use are built and managed by vendors, so I would have to impress upon them the impact of these errors and have them prioritize, then fix them. My question is whether or not this should be prioritized? Should I have them correct these errors sooner than later or can I take a phased approach? I haven't noticed any loss in traffic or anything like that, I'm more focused on what negative impact a "phased approach" could have. Any thoughts?

              Why has my search traffic suddenly tanked?

              On 6 June, Google search traffic to my Wordpress travel blog http://www.travelnasia.com tanked completely. There are no warnings or indicators in Webmaster Tools that suggest why this happened. Traffic from search has remained at zero since 6 June and shows no sign of recovering. Two things happened on or around 6 June. (1) I dropped my premium theme which was proving to be not mobile friendly and replaced it with the ColorMag theme which is responsive. (2) I relocated off my previous hosting service which was showing long server lag times to a faster host. Both of these should have improved my search performance, not tanked it. There were some problems with the relocation to the new web host which resulted in a lot of "out of memory" errors on the website for 3-4 days. The allowed memory was simply not enough for the complexity of the site and the volume of traffic. After a few days of trying to resolve these problems, I moved the site to another web host which allows more PHP memory and the site now appears reliably accessible for both desktop and mobile. But my search traffic has not recovered. I am wondering if in all of this I've done something that Google considers to be a cardinal sin and I can't see it. The clues I'm seeing include: Moz Pro was unable to crawl my site last Friday. It seems like every URL it tried to crawl was of the form http://www.travelnasia.com/wp-login.php?action=jetpack-sso&redirect_to=http://www.travelnasia.com/blog/bangkok-skytrain-bts-mrt-lines which resulted in a 500 status error. I don't know why this happened but I have disabled the Jetpack login function completely, just in case it's the problem. GWT tells me that some of my resource files are not accessible by GoogleBot due to my robots.txt file denying access to /wp-content/plugins/. I have removed this restriction after reading the latest advice from Yoast but I still can't get GWT to fetch and render my posts without some resource errors. On 6 June I see in Structured Data of GWT that "items" went from 319 to 1478 and "items with errors" went from 5 to 214. There seems to be a problem with both hatom and hcard microformats but when I look at the source code they seem to be OK. What I can see in GWT is that each hcard has a node called "n [n]" which is empty and Google is generating a warning about this. I see that this is because the author vcard URL class now says "url fn n" but I don't see why it says this or how to fix it. I also don't see that this would cause my search traffic to tank completely. I wonder if anyone can see something I'm missing on the site. Why would Google completely deny search traffic to my site all of a sudden without notifying any kind of penalty? Note that I have NOT changed the content of the site in any significant way. And even if I did, it's unlikely to result in a complete denial of traffic without some kind of warning.

              Difference between search volume in KWT and Impressions in GWT

              Hi there, Sorry I've been a bit quiet of late, we're going through a huge rebranding exercise as well as staying on top of client work. Anyway. I've got an issue with keyword research phase of a client remarketing. Trying to decide which keywords to target (aren't we all?) The client has 3 months of back data in Google Webmaster Tools, which helps us to see Impressions, CTR and actual click-throughs etc. Now, they rank #1 on Google.com for a certain keyword (logged out, of course). According to Google Keyword tool (Logged in) there are 2.7million searches per month for this keyword. With the average CTR being 18% for a #1 keyword that should be bringing in 400k visits. However, take the same keyword in Google Webmaster Tools and the impressions are actually around 1,600 per month with a CTR of 9%. Different CTR's for different sectors I can accept. What I don't get is the vast difference between the impressions in GWT compared to the alleged search volume coming from the Keyword tool. Really need to understand this so we can better select keywords and judge approximate traffic expected if ranking #1 for a keyword. Any help would be really useful. Thank you!
