      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.

        -Mike

          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

            .com vs .co.uk

            Hi, we are a UK based company and we have a lot of links from .com websites. Does the fact that they are .com or .co.uk affect the quality of the links for a UK website?

            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.

            Description vs meta description

            I have an e-commerce website and am trying to create product category pages. I am under the impression that Description is the text that would appear under the title on a google search and I believe the meta description is just what google reads? Is having BOTH important or just description? Is it ok to duplicate the description for the meta description? I know its not good to duplicate descriptions on other products and pages.

            Hreflang in vs. sitemap?

            Hi all, I decided to identify alternate language pages of my site via sitemap to save our development team some time.  I also like the idea of having leaner markup. However, my site has many alternate language and country page variations, so after creating a sitemap that includes mostly tier 1 and tier 2 level URLs, i now have a sitemap file that's 17mb.  I did a couple google searches to see is sitemap file size can ever be an issue and found a discussion or two that suggested keeping the size small and a really old article that recommended keeping it < 10mb. Does the sitemap file size matter?  GWT has verified the sitemap and appears to be indexing the URLs fine. Are there any particular benefits to specifying alternate versions of a URL in vs. sitemap? Thanks, -Eugene

            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

            What are partial urls and why this is causing a sitemap error?

            Hi mozzers, I have a client that recorded 7 errors when generating Xml sitemap. One of the errors appear to be coming from partial urls and apparently I would need to exclude them from sitemap. What are they exactly and why would they cause an error in the sitemap. Thanks!

            How important are sitemap errors?

            If there aren't any crawling / indexing issues with your site, how important do thing sitemap errors are? Do you work to always fix all errors? I know here: http://www.seomoz.org/blog/bings-duane-forrester-on-webmaster-tools-metrics-and-sitemap-quality-thresholds Duane Forrester mentions that sites with many 302's 301's will be punished--does any one know Googe's take on this?

            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
