      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

            Crawl Stats Decline After Site Launch (Pages Crawled Per Day, KB Downloaded Per Day)

            Hi all, I have been looking into this for about a month and haven't been able to figure out what is going on with this situation. We recently did a website re-design and moved from a separate mobile site to responsive. After the launch, I immediately noticed a decline in pages crawled per day and KB downloaded per day in the crawl stats. I expected the opposite to happen as I figured Google would be crawling more pages for a while to figure out the new site. There was also an increase in time spent downloading a page. This has went back down but the pages crawled has never went back up. Some notes about the re-design: URLs did not change Mobile URLs were redirected Images were moved from a subdomain (images.sitename.com) to Amazon S3 Had an immediate decline in both organic and paid traffic (roughly 20-30% for each channel) I have not been able to find any glaring issues in search console as indexation looks good, no spike in 404s, or mobile usability issues. Just wondering if anyone has an idea or insight into what caused the drop in pages crawled? Here is the robots.txt and attaching a photo of the crawl stats. User-agent: ShopWiki Disallow: / User-agent: deepcrawl Disallow: / User-agent: Speedy Disallow: / User-agent: SLI_Systems_Indexer Disallow: / User-agent: Yandex Disallow: / User-agent: MJ12bot Disallow: / User-agent: BrightEdge Crawler/1.0 (crawler@brightedge.com) Disallow: / User-agent: * Crawl-delay: 5 Disallow: /cart/ Disallow: /compare/ ```[fSAOL0](https://ibb.co/fSAOL0)

            [Very Urgent] More 100 "/search/adult-site-keywords" Crawl errors under Search Console

            I just opened my G Search Console and was shocked to see more than 150 Not Found errors under Crawl errors. Mine is a Wordpress site (it's consistently updated too): Here's how they show up: Example 1: URL: www.example.com/search/adult-site-keyword/page2.html/feed/rss2 Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword/page2.html Example 2 (this surprised me the most when I looked at the linked from data): URL: www.example.com/search/adult-site-keyword-2.html/page/3/ Linked From: www.example.com/search/adult-site-keyword-2.html/page/2/ (this is showing as if it's from our own site) http://a-spammy-adult-site.com/search/adult-site-keyword-2.html Example 3: URL: www.example.com/search/adult-site-keyword-3.html Linked From: http://an-adult-image-hosting.com/search/adult-site-keyword-3.html How do I address this issue?

            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

            Google Adsbot crawling order confirmation pages?

            Hi, We have had roughly 1000+ requests per 24 hours from Google-adsbot to our confirmation pages. This generates an error as the confirmation page cannot be viewed after closing or by anyone who didn't complete the order. How is google-adsbot finding pages to crawl that are not linked to anywhere on the site, in the sitemap or linked to anywhere else? Is there any harm in a google crawler receiving a higher percentage of errors - even though the pages are not supposed to be requested. Is there anything we can do to prevent the errors for the benefit of our network team and what are the possible risks of any measures we can take? This bot seems to be for evaluating the quality of landing pages used in for Adwords so why is it trying to access confirmation pages when they have not been set for any of our adverts? We included "Disallow: /confirmation" in the robots.txt but it has continued to request these pages, generating a 403 page and an error in the log files so it seems Adsbot doesn't follow robots.txt. Thanks in advance for any help, Sam

            Onsite SEO vs Offsite SEO

            Hey I know the importance of both onsite & offsite, primarily with regard to outreach/content/social. One thing I am trying to determine at the moment, is how much do I invest in offsite. My current focus is to improve our onpage content on product pages, which is taking some time as we have a small team. But I also know our backlinks need to improve. I'm just struggling on where to spend my time. Finish the onsite stuff by section first, or try to do a bit of both onsite/offsite at the same time?

            Would it be better to Start Over vs doing a Website Migration?

            Hey guys /gals I have a question please.  I have a computer repair business that does extremely well in search and is on the front page of google for anything computer repair related. However, I am currently re-branding my company and have completely redesigned every aspect of the UI and the SEO Site structure as well as the fact that I have completely written vastly different content and different title tag lines and meta descriptions for each page. So basically when doing a migration we know that we want to keep our content, titles, headlines and meta descriptions the same as to not lose our page rank. Seeing that I have completely went against the grain in all directions on a much needed company re-branding and everything is completely different from the old site is it even worthwhile 301 redirecting my old urls to the new ones that would (best) correspond with the new? In the plainest English, would I do better at Ranking the New Website QUICKER without doing 301 redirects from the OLD to the NEW? In an EXTREME instance like what I have done, would the Domain Migration IMPEDED me ranking the new site seeing how nothing is the same? I have build a Rock solid SILO Site Architecture on the New site which is WordPress using the Thesis Framework and the old domain is built on JOOMLA 1.5 Thank fellas Marshall

            External 404 vs Internal 404

            Which one is bad? External - when someone adds an incorrect link to your site, maybe does a typo when linking to an inner page. This page never existed on your site, google shows this as a 404 in Webmaster tools. Internal - a page existed, google indexed it, and you deleted it and didnt add a 301. Internal ones are in the webmaster's control, and i can understand if google gets upset if it sees a 404 for a URL that existed before, however surely "externally created" 404 shoudnt cause any harm cause that page never existed. And someone has inserted an incorrect link to your site.
