Mobile Googlebot vs Desktop Googlebot - GWT reports - Crawl errors
-
Hi Everyone,
I have a very specific SEO question. I am doing a site audit and one of the crawl reports is showing tons of 404's for the "smartphone" bot and with very recent crawl dates. If our website is responsive, and we do not have a mobile version of the website I do not understand why the desktop report version has tons of 404's and yet the smartphone does not. I think I am not understanding something conceptually.
I think it has something to do with this little message in the Mobile crawl report.
"Errors that occurred only when your site was crawled by Googlebot (errors didn't appear for desktop)."
If I understand correctly, the "smartphone" report will only show URL's that are not on the desktop report. Is this correct?

Hey Carla,
I'm not entirely sure what you're saying with:
"one of the crawl reports is showing tons of 404's for the "smartphone" bot and with very recent crawl dates. If our website is responsive, and we do not have a mobile version of the website I do not understand why the desktop report version has tons of 404's and yet the smartphone does not. I think I am not understanding something conceptually."
You say that the smartphone bot is seeing tons of 404s and the desktop report is showing tons of 404s, but the smartphone does not. If you can clarify that, I can probably better answer your question.
However, the answer is likely that Google may decide not to crawl URLs that it has already identified as 404s in one context. That is to say if they identify URLs on the mobile device as 404s they will know not to crawl them if they encounter them on desktop and vice versa.

Ok I forgot to add something to this as well. Why would the URLS show up on the smartphone report if they are not on the desktop report? Afterall a 404 from either device is still a 404?
Thanks

My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages.
Hello, My last site crawl shows over 700 404 errors all with void(0 added to the ends of my posts/pages. I have contacted my theme company but not sure what could have done this. Any ideas? The original posts/pages are still correct and working it just looks like it did duplicates and added void(0 to the end of each post/page. Questions: There is no way to undo this correct? Do I have to do a redirect on each of these? Will this hurt my rankings and domain authority? Any suggestions would be appreciated. Thanks, Wade

Duplicate H1 on single page for mobile and desktop
I have a responsive site and whilst this works and is liked by google from a user perspective the pages could look better on mobile. I have a wordpress site and use the Divi Builder with elegant themes and have developed a separate page header for mobile that uses a manipulated background image and smaller H1 font size. When crawling the site two H1s can be detected on the same page - they are exactly the same words and only one will show according to device. However, I need to know if this will cause me a problem with google and SEO. As the mobile changes are not just font size but also adaptations to some visual elements it is not something I can simply alter in the CSS. Would appreciate some input as to whether this is a problem or not

Two websites vs each other owned by same company
My client owns a brand and came to me with two ecommerce websites. One website sells his specific brand product and the other sells general products in his niche (including his branded product). Question is my client wants to rank each website for basically the same set of keywords. We have two choices I'd like feedback on- Choice 1 is to rank both websites for same keyword groupings so even if they are both on page 1 of the serps then they take up more real estate and share of voice. are there any negative possibilities here? Choice 2 is to recommend a shift in the position of the general industry website to bring it further away from the industry niche by focusing on different keywords so they don't compete with each other in the serps. I'm for choice 1, what about you?

Prevent Google from crawling Ajax
With Google figuring out how to make Ajax and JS more searchable/indexable, I am curious on thoughts or techniques to prevent this. Here's my Situation, we have a page that we do not ever want to be indexed/crawled or other. Currently we have the nofollow/noindex command, but due to technical changes for our site the method in which this information is being implemented if it is ever displayed it will not have the ability to block the content from search. It is also the decision of the business to not list the file in robots.txt due to the sensitivity of the content. Basically, this content doesn't exist unless something super important happens, and even if something super important happens, we do not want Google to know of its existence. Since the Dev team is planning on using Ajax/JS to pull in this content if the business turns it on, the concern is that it will be on the homepage and Google could index it. So the questions that I was asked; if Google can/does index, how long would that piece of content potentially appear in the SERPs? Can we block Google from caring about and indexing this section of content on the homepage? Sorry for the vagueness of this question, it's very sensitive in nature and I am trying to avoid too many specifics. I am able to discuss this in a more private way if necessary. Thanks!

Google crawling different content--ever ok?
Here are a couple of scenarios I'm encountering where Google will crawl different content than my users on initial visit to the site--and which I think should be ok. Of course, it is normally NOT ok, I'm here to find out if Google is flexible enough to allow these situations: 1. My mobile friendly site has users select a city, and then it displays the location options div which includes an explanation for why they may want to have the program use their gps location. The user must choose the gps, the entire city, or he can enter a zip code, or choose a suburb of the city, which then goes to the link chosen. OTOH it is programmed so that if it is a Google bot it doesn't get just a meaningless 'choose further' page, but rather the crawler sees the page of results for the entire city (as you would expect from the url), So basically the program defaults for the entire city results for google bot, but for for the user it first gives him the initial ability to choose gps. 2. A user comes to mysite.com/gps-loc/city/results The site, seeing the literal words 'gps-loc' in the url goes out and fetches the gps for his location and returns results dependent on his location. If Googlebot comes to that url then there is no way the program will return the same results because the program wouldn't be able to get the same long latitude as that user. So, what do you think? Are these scenarios a concern for getting penalized by Google? Thanks, Ted

What if page exists for desktop but not mobile?
I have a domain (no subdomains) that serves up different dynamic content for mobile/desktop pages--each having the exact same page url, kind of a semi responsive design, and will be using "Vary: User-Agent" to give Google a heads up on this setup. However, some of the pages are only valid for mobile or only valid for desktop. In the case of when a page is valid only for mobile (call it mysite.com/mobile-page-only ), Google Webmaster Tools is giving me a soft 404 error under Desktop, saying that the page does not exist, Apparently it is doing that because my program is actually redirecting the user/crawler to the home page. It appears from the info about soft 404 errors that Google is saying since it "doesn't exist" I should give the user a 404 page--which I can make it customized and give the user an option to go to the home page, or choose links from a menu, etc.. My concern is that if I tell the desktop bot that mysite.com/mobile-page-only basically is a 404 error (ie doesn't exist), that it could mess up the mobile bot indexing for that page--since it definitely DOES exist for mobile users.. Does anyone here know for sure that Google will index a page for mobile that is a 404 not found for desktop and vice versa? Obviously it is important to not remove something from an index in which it belongs, so whether Google is careful to differential the two is a very important issue. Has anybody here dealt with this or seen anything from Google that addresses it? Might one be better off leaving it as a soft 404 error? EDIT: also, what about Bing and Yahoo? Can we assume they will handle it the same way? EDIT: closely related question--in a case like mine does Google need a separate sitemap for the valid mobile pages and valid desktop pages even though most links will be in both? I can't tell from reading several q&a on this. Thanks, Ted

Lowercase VS. Uppercase Canonical tags?
Hi MOZ, I was hoping that someone could help shed some light on an issue I'm having with URL structure and the canonical tag. The company I work for is a distributor of electrical products and our E-commerce site is structured so that our URL's (specifically, our product detail page URL's) include a portion (the part #) that is all uppercase (e.g: buy/OEL-Worldwide-Industries/AFW-PG-10-10). The issue is that we have just recently included a canonical tag in all of our product detail pages and the programmer that worked on this project has every canonical tag in lowercase instead of uppercase. Now, in GWT, I'm seeing over 20,000-25,000 "duplicate title tags" or "duplicate descriptions". Is this an issue? Could this issue be resolved by simply changing the canonical tag to reflect the uppercase URL's? I'm not too well versed in canonical tags and would love a little insight. Thanks!
