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

Best SEO for table in mobile view
I'm wondering what the best way to present a table for mobile view in terms of SEO? It's a complicated table (not simple rows & columns but also col spans) which doesn't work with any responsive techniques I can find. I can offer different content for desktop / mobile so desktop is OK. But what's the best way forward with Google for mobile? I could offer a jpg or simply an explanation to revisit the page on desktop, but neither of those options seem particularly Google-friendly?

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.

M.ExampleSite vs mobile.ExampleSite vs ExampleSite.com
Hi, I have a call with a potential client tomorrow where all I know is that they are wigged-out about canonicalization, indexing and architecture for their three sites: m.ExampleSite.com mobile.ExampleSite.com ExampleSite.com The sites are pretty large... 350k for the mobiles and 5 million for the main site. They're a retailer with endless products. They're main site is not mobile-responsive, which is evidently why they have the m and mobile sites. Why two, I don't know. This is how they currently hand this: What would you suggest they do about this? The most comprehensive fix would be making the main site mobile responsive and 301 the old mobile sub domains to the main site. That's probably too much work for them. So, what more would you suggest and why? Your thoughts? Best... Mike P.S., Beneath my hand-drawn portrait avatar above it says "Staff" at this moment, which I am not. Some kind of bug I guess.

LinkedIn 999 HTTP Errors
I am working on a website, https://linkedinforbusiness.net and a ton of 999 HTTP errors have only now surfaced. I would venture from reading the "Request denied" error in the log, LinkedIn means to block BLCs attempts to check those links. It might be because the site has a lot of LinkedIn links; maybe they find it suspicious that the server is sending a lot of requests for their links. How do you see this? Any fixes? What level of harm do you think it brings to the site? I have removed all similar links to LinkedIn from my site to avoid this (https://www.hillwebcreations.com). However, this isn't so easily done for LinkedIn For Business, as her work in all about helping businesses and individuals optimize their use of LinkedIn.

Canonical tag + HREFLANG vs NOINDEX: Redundant?
Hi, We launched our new site back in Sept 2013 and to control indexation and traffic, etc we only allowed the search engines to index single dimension pages such as just category, brand or collection but never both like category + brand, brand + collection or collection + catergory We are now opening indexing to double faceted page like category + brand and the new tag structure would be: For any other facet we're including a "noindex, follow" meta tag. 1. My question is if we're including a "noindex, follow" tag to select pages do we need to include a canonical or hreflang tag afterall? Should we include it either way for when we want to remove the "noindex"? 2. Is the x-default redundant? Thanks for any input. Cheers WMCA

Do search engines crawl links on 404 pages?
I'm currently in the process of redesigning my site's 404 page. I know there's all sorts of best practices from UX standpoint but what about search engines? Since these pages are roadblocks in the crawl process, I was wondering if there's a way to help the search engine continue its crawl. Does putting links to "recent posts" or something along those lines allow the bot to continue on its way or does the crawl stop at that point because the 404 HTTP status code is thrown in the header response?

301 or 302 Redirects to Mobile Site
When it's detected that a mobile device is accessing the site it has the ability to redirect from www.example.com to m.example.com. Does it make more sense to employ a 301 or 302 redirect here? Google says a 301 but does not explain why (although usually I stick to "when in doubt, 301") . It seems like a 302 would prevent passing link juice to the mobile site and having mobile-optimized results also showing up in Google's index. What is the preference here?

How to stop Google crawling after 301 redirect?
I have removed all pages from my old website and set 301 redirect to new website. But, I have verified old website with Google webmaster tools' HTML verification file which enable me to track all data and existence of pages in Google search for my old website. I was assumed that, Google will stop crawling and DE-indexed all pages after 301 redirect. Because, I have set 301 redirect before 3 months. Now, I'm able to see Google bot activity on my website with help of Google webmaster tools. You can find out attachment to know more about it. How can it possible & How Google can crawl removed pages? You can see following image to know more about it. First & Second
