      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?

        Very important.  Particularly if you have a large site.  We operate a large site with 100,000's of pages and as Dan said it can be difficult to maintain.  We use something called Unlimited XML Sitemap Generator which builds XML sitemaps for us automatically.  I'd highly recommend it although it takes a bit of fiddling with to get it up and running as it's software which sits on site.  We couldn't manage without it as we'd be forever on sitemaps.

        We found that getting sitemaps right on a large site made a huge difference to the crawl rate that we encountered in GWT and a huge indexation to follow.

        In particular check for 302's.  I made the mistake of leaving those for a while and am sure that we suffered from some loss of link equity along the way.

        Hope it helps

          Your sitemap should only list pages that actually exist.

          If you delete some pages, then you need to rebuild the sitemap.

          Ditto if you delete them and redirect.

          Google is always lagging, so if you delete 10 pages and then update the sitemap, even if google downloads the sitemap immediately, they will still be running crawls on the old map, and they may be crawling the now-missing pages, but haven't shown the failures in your WMT yet.

          If you update your sitemap quickly, it is possible they will never crawl the missing pages and get a 404 or 301.

          (but of course, there could be other sites pointing to the now-missing pages, and the 404s will show up elsewhere as missing)

          I am always checking, adding, deleting and redirecting pages, and I update the current sitemap every hour and all the others are rebuilt at midnight every night. I usually do deletions just before midnight if I can, to minimize the time the sitemap is out of sync.

            As far as I know Google is more lenient with sitemap errors, but I would still recommend looking into it. The first step would be to be sure your sitemap is up to date to begin with - and has all the URLs you want (and not any you don't want). The main thing is none of them should 404 and then beyond that, yes, they should return 200's.

            Unless you're dealing with a gigantic site which might be hard to maintain, in theory there shouldn't be errors in sitemaps if you have the correct URLs in there.

            Even better, if you're running WordPress the Yoast SEO plugin will generate an XML sitemap for you and it update automatically.

            Hope that helps!

            -Dan

              Is possible to submit a XML sitemap to Google without using Google Search Console?

              We have a client that will not grant us access to their Google Search Console (don't ask us why). Is there anyway possible to submit a XML sitemap to Google without using GSC? Thanks

              Sitemap with homepage URL repeated several times - it is a problem?

              Hello Mozzers, I am looking at a website with the homepage repeated several times (4 times) on the sitemap (sitemap is autogenerated via a plugin) - is this an SEO problem do you think - might it damage SEO performance, or can I ignore this issue? I am thinking I can ignore, yet it's an odd "issue" so your advice would be welcome! Thanks, Luke

              Sitemap generator which only includes canonical urls

              Does anyone know of a 3rd party sitemap generator that will only include the canonical url's?  Creating a sitemap with geo and sorting based parameters isn't the most ideal way to generate sitemaps.  Please let me know if anyone has any ideas.  Mind you we have hundreds of thousands of indexed url's and this can't be done with a simple text editor.

              Sitemap on a Subdomain

              Hi, For various reasons I placed my sitemaps on a subdomain where I keep images and other large files (static.example.com). I then submitted this to Google as a separate site in Webmaster tools. Is this a problem? All of the URLs are for the actual site (www.example.com), the only issue on my end is not being able to look at it all at the same time. But I'm wondering if this would cause any problems on Google's end.

              Google Not Indexing XML Sitemap Images

              Hi Mozzers, We are having an issue with our XML sitemap images not being indexed. The site has over 39,000 pages and 17,500 images submitted in GWT.  If you take a look at the attached screenshot, 'GWT Images - Not Indexed', you can see that the majority of the pages are being indexed - but none of the images are. The first thing you should know about the images is that they are hosted on a content delivery network (CDN), rather than on the site itself. However, Google advice suggests hosting on a CDN is fine - see second screenshot, 'Google CDN Advice'.  That advice says to either (i) ensure the hosting site is verified in GWT or (ii) submit in robots.txt.  As we can't verify the hosting site in GWT, we had opted to submit via robots.txt. There are 3 sitemap indexes: 1) http://www.greenplantswap.co.uk/sitemap_index.xml, 2) http://www.greenplantswap.co.uk/sitemap/plant_genera/listings.xml and 3) http://www.greenplantswap.co.uk/sitemap/plant_genera/plants.xml. Each sitemap index is split up into often hundreds or thousands of smaller XML sitemaps. This is necessary due to the size of the site and how we have decided to pull URLs in.  Essentially, if we did it another way, it may have involved some of the sitemaps being massive and thus taking upwards of a minute to load. To give you an idea of what is being submitted to Google in one of the sitemaps, please see view-source:http://www.greenplantswap.co.uk/sitemap/plant_genera/4/listings.xml?page=1. Originally, the images were SSL, so we decided to reverted to non-SSL URLs as that was an easy change.  But over a week later, that seems to have had no impact.  The image URLs are ugly... but should this prevent them from being indexed? The strange thing is that a very small number of images have been indexed - see http://goo.gl/P8GMn. I don't know if this is an anomaly or whether it suggests no issue with how the images have been set up - thus, there may be another issue. Sorry for the long message but I would be extremely grateful for any insight into this.  I have tried to offer as much information as I can, however please do let me know if this is not enough. Thank you for taking the time to read and help. Regards, Mark Oz6HzKO rYD3ICZ

              Canonical URLs and Sitemaps

              We are using canonical link tags for product pages in a scenario where the URLs on the site contain category names, and the canonical URL points to a URL which does not contain the category names.  So, the product page on the site is like www.example.com/clothes/skirts/skater-skirt-12345, and also like www.example.com/sale/clearance/skater-skirt-12345 in another category.  And on both of these pages, the canonical link tag references a 3rd URL like www.example.com/skater-skirt-12345.  This 3rd URL, used in the canonical link tag is a valid page, and displays the same content as the other two versions, but there are no actual links to this generic version anywhere on the site (nor external). Questions: 1. Does the generic URL referenced in the canonical link also need to be included as on-page links somewhere in the crawled navigation of the site, or is it okay to be just a valid URL not linked anywhere except for the canonical tags? 2. In our sitemap, is it okay to reference the non-canonical URLs, or does the sitemap have to reference only the canonical URL?  In our case, the sitemap points to yet a 3rd variation of the URL, like www.example.com/product.jsp?productID=12345.  This page retrieves the same content as the others, and includes a canonical link tag back to www.example.com/skater-skirt-12345.  Is this a valid approach, or should we revise the sitemap to point to either the category-specific links or the canonical links?

              Xml sitemap advice for website with over 100,000 articles

              Hi, I have read numerous articles that support submitting multiple XML sitemaps for websites that have thousands of articles... in our case we have over 100,000.  So, I was thinking I should submit one sitemap for each news category. My question is how many page levels should each sitemap instruct the spiders to go?  Would it not be enough to just submit the top level URL for each category and then let the spiders follow the rest of the links organically? So, if I have 12 categories the total number of URL´s will be 12??? If this is true, how do you suggest handling or home page, where the latest articles are displayed regardless of their category... so I.E. the spiders will find l links to a given article both on the home page and in the category it belongs to.  We are using canonical tags. Thanks, Jarrett

              Create a new XML Sitemap for a blog subdomain?

              What would be the best way to go about this? A site just put a blog on http://blog.domain.com/ Should there be a separate XML Sitemap for that particular subdomain or should the original XML Sitemap for the main domain be sufficient? Looking forward to your responses. Thanks
