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

Monica,
I'm going to open a new thread to ask a similar question, as I think I didn't ask it very well.
Thanks for your input,
Ted

Thanks. If I understand you, the mobile bot won't crawl a url that the desktop bot has said needs to be fixed for it to work right for desktop. . Would you agree that doesn't really sound right on Google's part, since the url is fine for mobile use? I don't know why it wouldn't crawl for mobile, but if that's the way it is I can try fixing it on desktop to see if that enables the mobile to get crawled.
Once I do that I guess I'll find out whether a 404 not found for desktop will disable it from crawling for mobile (yes that link is accessible from other pages)--I was hoping to avoid trial and error on that because the time lag seems like it would be hard to pin down.
In a nutshell here's what I'm concerned will happen:
Google mobile bot crawls my mobile page and indexes it: Then the desktop bot crawls the same url and gets a 404 not found. Because of the desktop not found, Google removes it from the mobile page index.
I don't see a good way to test that since it depends on when each crawler is crawling. And, if this is what it is doing, I can't think of a good solution to having a responsive site with some content meant only for mobile indexing or only for desktop indexing.

If a URL is labeled a 404 it will not be crawled again unless there is a reason to, you mark it as fixed, or you edit the link in some form or fashion. Mark it as fixed and see if the error comes back. There is no harm in doing this.
Can you get to the page on your mobile device just by clicking through your site? If you can, that is good, it will eventually encourage a mobile bot to crawl it. If you can fetch and render as google, then I would just give it some time. I am not sure if there is a string of code you can add to the head of that page telling the robots that it is a mobile only page. I don't know how that works.
I would just mark it as fixed right now and see what happens over the next couple of days.

Hi Monica-thanks for your reply:
Ok, for a page that is supposed to be mobile only within a responsive-like setup(ie one domain) here's what I see:
The desktop bot crawls the link and gives a soft 404 error -- presumably because the page is currently being redirected to the home page.
The mobile bot is not crawling that link despite it being prominent on the main site home page, as my dbase is tracking the bot crawling and is not showing that it crawled that link for mobile (but is for desktop), and a search on my smartphone doesn't show that link either (even though it does show other links for pages used by both).. **Yet, if I fetch the mobile only page in webmaster tools using their mobile bot it finds it and renders it perfectly. ** So, why isn't it crawling it? Is it because when the mobile bot crawls it first looks and sees that that link is already 'flagged' as a soft 404 for the desktop? Or, is it because the mobile crawler is getting hung up on a link on the home page for mobile that has nothing to do with this mobile-only link?
It appears that the mobile bot is influenced by the desktop bot results--which is my fear: It seems to me their 2 bots should be independent of each other. If they aren't independent then if I change it to a 404 not found for desktop, would that even help, or would that prevent the mobile bot from ever trying to crawl it?
I would think that anybody who has a responsive page design and has blocked out certain content so that it renders only for mobile or only for non-mobile has had to face this issue.
Not sure what to do--I could fix the soft errors--change them to 404 not found and just see then if Google starts indexing for mobile or not, but was hoping to get some feedback before experimenting.
Thanks again, and please share more if you have more thoughts!

Did you look at your Mobile 404 errors? Google uses a different bot for mobile sites and anything related to that mobile page. Chances are, if it isn't reflecting a 404 in the Mobile errors in GWT, it is being indexed properly.
Check it out from you phone. Google the exact keyword and your company name. See if you can get to the page and if it is in fact the correct page.

Should I apply Canonical Links from my Landing Pages to Core Website Pages?
I am working on an SEO project for the website: https://wave.com.au/ There are some core website pages, which we want to target for organic traffic, like this one: https://wave.com.au/doctors/medical-specialties/anaesthetist-jobs/ Then we have basically have another version that is set up as a landing page and used for CPC campaigns. https://wave.com.au/anaesthetists/ Essentially, my question is should I apply canonical links from the landing page versions to the core website pages (especially if I know they are only utilising them for CPC campaigns) so as to push link equity/juice across? Here is the GA data from January 1 - April 30, 2019 (Behavior > Site Content > All Pages😞

Category pages
I am a very basic question on managing categories in WordPress. We have an Android website, and we cover news, rumors, tips and tricks about new devices. We have been creating categories for the new devices or at least for the popular ones which are launched every year, and link to them internally with the hope that it would improve the page authority and ranking. For example, we have a category page for Moto X, another one for Moto X (2014) and one more for Moto X (2015). One of the reasons for creating a category was to ensure that it is easier for readers to get information about a particular device rather than going to a category page that has information about all the models. However, the problem with their strategy we're now realizing is that it means we have to build page authority for the new category page from scratch, which can take time. So we are thinking of reusing the same category for multiple models. So reuse the Moto X category page for Moto X (2016). However, we are not sure if it would be right approach as we would be linking to the same category page with different anchor texts. So while it would be good to reuse a page rather than rebuild the page authority from scratch, would we be diluting the authority for the main keyword by using it for different models. I would love to hear your thoughts on how we should be handling categories and internal links in this case.

Landing pages, are my pages competing?
If I have identified a keyword which generates income and when searched in google my homepage comes up ranked second, should I still create a landing page based on that keyword or will it compete with my homepage and cause it to rank lower?

Redirecting 404 pages
Hello,We have a wordpress site that has some "hidden" pages with weird URL's. Due to the way the site was built (not by us) if we setup our standard practice for 404 pages some site functionality will be lost.Standard Practice for 404's www.domain.com/fafsaf shows 404 error pageProposed solution:- www.domain.com/safaf >forwards to> www.domain.com/404 - shows 404 error page. Will this stop the search engines indexing the pages? - we have also amended the robots.txt to try and stop some pages being indexed but we still keep finding the odd little "hidden" page.The aim is to try and get all the search engines just to index the few simple pages on the sitemap instead of finding all these extra pages.

Which index page should I canonical to?

On the index page, I have the following: I have never put any thought into which index path is the best to use. http://www.example.com http://www.example.com/ http://www.example.com/index.php Could someone shed some light on this for me? Does it make a difference? Thanks! Ryan

Dynamic pages - ecommerce product pages
Hi guys, Before I dive into my question, let me give you some background.. I manage an ecommerce site and we're got thousands of product pages. The pages contain dynamic blocks and information in these blocks are fed by another system. So in a nutshell, our product team enters the data in a software and boom, the information is generated in these page blocks. But that's not all, these pages then redirect to a duplicate version with a custom URL. This is cached and this is what the end user sees. This was done to speed up load, rather than the system generate a dynamic page on the fly, the cache page is loaded and the user sees it super fast. Another benefit happened as well, after going live with the cached pages, they started getting indexed and ranking in Google. The problem is that, the redirect to the duplicate cached page isn't a permanent one, it's a meta refresh, a 302 that happens in a second. So yeah, I've got 302s kicking about. The development team can set up 301 but then there won't be any caching, pages will just load dynamically. Google records pages that are cached but does it cache a dynamic page though? Without a cached page, I'm wondering if I would drop in traffic. The view source might just show a list of dynamic blocks, no content! How would you tackle this? I've already setup canonical tags on the cached pages but removing cache.. Thanks

Category Pages up - Product Pages down... what would help?
Hi I mentioned yesterday how one of our sites was losing rank on product pages. What steps do you take to improve the SERPS of product pages, in this case home/category/product is the tree. There isn't really any internal linking, except one link from the category page to each product, would setting up a host of internal links perhaps "similar products" linking them together be a place to start? How can I improve my ranking of these more deeply internal pages? Not just internal links?
