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

Googlebot being redirected but not users?
Hi, We seem to have a slightly odd issue. We noticed that a number of our location category pages were slipping off 1 page, and onto page 2 in our niche. On inspection, we noticed that our Arizona page had started ranking in place of a number of other location pages - Cali, Idaho, NJ etc. Weirdly, the pages they had replaced were no longer indexed, and would remain so, despite being fetched, tweeted etc. One test was to see when the dropped out pages had been last crawled, or at least cached. When conducting the 'cache:domain.com/category/location' on these pages, we were getting 301 redirected to, you guessed it, the Arizona page. Very odd. However, the dropped out pages were serving 200 OK when run through header checker tools, screaming frog etc. On the face of it, it would seem Googlebot is getting redirected when it is hitting a number of our key location pages, but users are not. Has anyone experienced anything like this? The theming of the pages are quite different in terms of content, meta etc. Thanks.

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

H2 vs. H3 Tags for Category Navigation
Hey, all. I have client that uses tags in the navigation for its blog. For example, tags might appear around "Library," "Recent Posts," etc. This is handled through their WordPress theme. This seems fairly standard, but I wonder whether tags are semantically appropriate. Since each blog post is fairly lengthy (about 500-1000 words) with multiple tags, would it be more appropriate to use tags for this menu navigation? Are we cutting into the effectiveness of our tags by using them for menu navigation? The navigation is certainly an important page element, and it structures content, so it seems that it should use some header tag. Anyways, your thoughts are greatly appreciated. I'm a content creator, not an SEO, so this is a bit out of my skillset.

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

Googlebot on paywall made with cookies and local storage
My question is about paywalls made with cookies and local storage. We are changing a website with free content to a open paywall with a 5 article view weekly limit. The paywall is made to work with cookies and local storage. The article views are stored to local storage but you have to have your cookies enabled so that you can read the free articles. If you don't have cookies enable we would pass an error page (otherwise the paywall would be easy to bypass). Can you say how this affects SEO? We would still like that Google would index all article pages that it does now. Would it be cloaking if we treated Googlebot differently so that when it does not have cookies enabled, it would still be able to index the page?

Wordtracker vs Google Keyword Tool
When I find keyword opportunities in Wordtracker, I'll sometimes run them through Adwords Keyword tool only to find that Google says these keywords have 0 search volume. Would you use these keywords even though Google says users aren't searching for them?

How to prevent Google from crawling our product filter?
Hi All, We have a crawler problem on one of our sites www.sneakerskoopjeonline.nl. On this site, visitors can specify criteria to filter available products. These filters are passed as http/get arguments. The number of possible filter urls is virtually limitless. In order to prevent duplicate content, or an insane amount of pages in the search indices, our software automatically adds noindex, nofollow and noarchive directives to these filter result pages. However, we’re unable to explain to crawlers (Google in particular) to ignore these urls. We’ve already changed the on page filter html to javascript, hoping this would cause the crawler to ignore it. However, it seems that Googlebot executes the javascript and crawls the generated urls anyway. What can we do to prevent Google from crawling all the filter options? Thanks in advance for the help. Kind regards, Gerwin
