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

Google Indexing Of Pages As HTTPS vs HTTP
We recently updated our site to be mobile optimized. As part of the update, we had also planned on adding SSL security to the site. However, we use an iframe on a lot of our site pages from a third party vendor for real estate listings and that iframe was not SSL friendly and the vendor does not have that solution yet. So, those iframes weren't displaying the content. As a result, we had to shift gears and go back to just being http and not the new https that we were hoping for. However, google seems to have indexed a lot of our pages as https and gives a security error to any visitors. The new site was launched about a week ago and there was code in the htaccess file that was pushing to www and https. I have fixed the htaccess file to no longer have https. My questions is will google "reindex" the site once it recognizes the new htaccess commands in the next couple weeks?

Location Pages On Website vs Landing pages
We have been having a terrible time in the local search results for 20 + locations. I have Places set up and all, but we decided to create location pages on our sites for each location - brief description and content optimized for our main service. The path would be something like .com/location/example. One option that has came up in question is to create landing pages / "mini websites" that would probably be location-example.url.com. I believe that the latter option, mini sites for each location, would be a bad idea as those kinds of tactics were once spammy in the past. What are are your thoughts and and resources so I can convince my team on the best practice.

Location.href vs href?
I just got off a Google Hangout with John Mueller and was left a little confused about his response to my question. If I have an internal link in a div like widgetwill it have the same SEO impact as widget John said that as you are unable to attribute a nofollow in an onclick event it would be treated as a naked link and would not pass pagerank but still be crawled. Can anyone confirm that I understood it correctly? If so should all my links that have such an onclickevent also have an html ahref in the too? Such as widget Many times it is more useful for the customer to click on any area of a large div and not just the link to get to the destination intended? Clarification on this subject would be very useful, there is nothing easily found online to confirm this. Thanks

Avoiding Duplicate Content with Used Car Listings Database: Robots.txt vs Noindex vs Hash URLs (Help!)
Hi Guys, We have developed a plugin that allows us to display used vehicle listings from a centralized, third-party database. The functionality works similar to autotrader.com or cargurus.com, and there are two primary components: 1. Vehicle Listings Pages: this is the page where the user can use various filters to narrow the vehicle listings to find the vehicle they want.
Intermediate & Advanced SEO | | browndoginteractive
2. Vehicle Details Pages: this is the page where the user actually views the details about said vehicle. It is served up via Ajax, in a dialog box on the Vehicle Listings Pages. Example functionality: http://screencast.com/t/kArKm4tBo The Vehicle Listings pages (#1), we do want indexed and to rank. These pages have additional content besides the vehicle listings themselves, and those results are randomized or sliced/diced in different and unique ways. They're also updated twice per day. We do not want to index #2, the Vehicle Details pages, as these pages appear and disappear all of the time, based on dealer inventory, and don't have much value in the SERPs. Additionally, other sites such as autotrader.com, Yahoo Autos, and others draw from this same database, so we're worried about duplicate content. For instance, entering a snippet of dealer-provided content for one specific listing that Google indexed yielded 8,200+ results: Example Google query. We did not originally think that Google would even be able to index these pages, as they are served up via Ajax. However, it seems we were wrong, as Google has already begun indexing them. Not only is duplicate content an issue, but these pages are not meant for visitors to navigate to directly! If a user were to navigate to the url directly, from the SERPs, they would see a page that isn't styled right. Now we have to determine the right solution to keep these pages out of the index: robots.txt, noindex meta tags, or hash (#) internal links. Robots.txt Advantages: Super easy to implement Conserves crawl budget for large sites Ensures crawler doesn't get stuck. After all, if our website only has 500 pages that we really want indexed and ranked, and vehicle details pages constitute another 1,000,000,000 pages, it doesn't seem to make sense to make Googlebot crawl all of those pages. Robots.txt Disadvantages: Doesn't prevent pages from being indexed, as we've seen, probably because there are internal links to these pages. We could nofollow these internal links, thereby minimizing indexation, but this would lead to each 10-25 noindex internal links on each Vehicle Listings page (will Google think we're pagerank sculpting?) Noindex Advantages: Does prevent vehicle details pages from being indexed Allows ALL pages to be crawled (advantage?) Noindex Disadvantages: Difficult to implement (vehicle details pages are served using ajax, so they have no tag. Solution would have to involve X-Robots-Tag HTTP header and Apache, sending a noindex tag based on querystring variables, similar to this stackoverflow solution. This means the plugin functionality is no longer self-contained, and some hosts may not allow these types of Apache rewrites (as I understand it) Forces (or rather allows) Googlebot to crawl hundreds of thousands of noindex pages. I say "force" because of the crawl budget required. Crawler could get stuck/lost in so many pages, and my not like crawling a site with 1,000,000,000 pages, 99.9% of which are noindexed. Cannot be used in conjunction with robots.txt. After all, crawler never reads noindex meta tag if blocked by robots.txt Hash (#) URL Advantages: By using for links on Vehicle Listing pages to Vehicle Details pages (such as "Contact Seller" buttons), coupled with Javascript, crawler won't be able to follow/crawl these links. Best of both worlds: crawl budget isn't overtaxed by thousands of noindex pages, and internal links used to index robots.txt-disallowed pages are gone. Accomplishes same thing as "nofollowing" these links, but without looking like pagerank sculpting (?) Does not require complex Apache stuff Hash (#) URL Disdvantages: Is Google suspicious of sites with (some) internal links structured like this, since they can't crawl/follow them? Initially, we implemented robots.txt--the "sledgehammer solution." We figured that we'd have a happier crawler this way, as it wouldn't have to crawl zillions of partially duplicate vehicle details pages, and we wanted it to be like these pages didn't even exist. However, Google seems to be indexing many of these pages anyway, probably based on internal links pointing to them. We could nofollow the links pointing to these pages, but we don't want it to look like we're pagerank sculpting or something like that. If we implement noindex on these pages (and doing so is a difficult task itself), then we will be certain these pages aren't indexed. However, to do so we will have to remove the robots.txt disallowal, in order to let the crawler read the noindex tag on these pages. Intuitively, it doesn't make sense to me to make googlebot crawl zillions of vehicle details pages, all of which are noindexed, and it could easily get stuck/lost/etc. It seems like a waste of resources, and in some shadowy way bad for SEO. My developers are pushing for the third solution: using the hash URLs. This works on all hosts and keeps all functionality in the plugin self-contained (unlike noindex), and conserves crawl budget while keeping vehicle details page out of the index (unlike robots.txt). But I don't want Google to slap us 6-12 months from now because it doesn't like links like these (). Any thoughts or advice you guys have would be hugely appreciated, as I've been going in circles, circles, circles on this for a couple of days now. Also, I can provide a test site URL if you'd like to see the functionality in action.0 -
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!

Why is my Crawl Report Showing Thousands of Pages that Do Not Exist?
Hi, I just downloaded a Crawl Summary Report for a client's website. I am seeing THOUSANDS of duplicate page content errors. The overwhelming majority of them look something like this: ERROR: http://www.earlyinterventionsupport.com/resources/parentingtips/development/parentingtips/development/development/development/development/development/development/parentingtips/specialneeds/default.aspx This page doesn't exist and results in a 404 page. Why are these pages showing up? How do I get rid of them? Are they endangering the health of my site as a whole? Thank you, Jenna <colgroup><col width="1051"></colgroup>

URL Error or Penguin Penalty?
I am currently having a major panic as our website www.uksoccershop.com has been largely dropped from Google. We have not made any changes recently and I am not sure why this is happening, but having heard all sorts of horror stories of penguin update, I am fearing the worst. If you google "uksoccershop" you will see that the homepage does not rank. We previously ranked in the top 3 for "football shirts" but now we don't, although on page 2, 3 and 4 you will see one of our category pages ranking (this didn't used to happen). Some rankings are intact, but many have disappeared completely and in some cases been replaced by other pages on our site. I should point out our existing rankings have been consistently there for 5-6 years until today. I logged into webmaster tools and thankfully there is no warning message from Google about spam, etc, but what we do have is 35,000 URL errors for pages which are accessible. An example of this is: | URL: | http://www.uksoccershop.com/categories/5_295_327.html | | Error details In Sitemaps Linked from Last crawled: 6/20/12First detected: 6/15/12Googlebot couldn't access the contents of this URL because the server had an internal error when trying to process the request. These errors tend to be with the server itself, not with the request. Is it possible this is the cause of the issue (we are not currently sure why the URL's are being blocked) and if so, how severe is it and how recoverable?If that is unlikely to cause the issue, what would you recommend our next move is?All help is REALLY REALLY appreciated 🙂
