      Hey guys,

      I run a dynamic web service and I will start building static sitemaps for it pretty soon. The fact that my app lives in a multitude of servers doesn't make it easy to distribute frequently updated static files throughout the servers.

      My idea was to host the files in AWS S3 and point my robots.txt sitemap directive there. I'll use a sitemap index so, every other sitemap will be hosted on S3 as well.

      I could dynamically mirror the content from the files in S3 through my app, but that would be a little more resource intensive than just serving the static files from a common place.

      Any ideas? Thanks!

        My general take on this sort of scenario is first to eliminate all the redundant hostnames with round-robin DNS, through adding extra server power with software-based load-balancing in the interim with a solution like InterWorx, and breaking out database servers.   If you do that, you should have a nice little server cluster that's crazy efficient.and scalable.  You can add a CDN to the mix if you like as well.  With all of that, SEO should work the same way as on a single server.

        Sitemaps can then be generated dynamically really easily (in under 25 lines of code, most of the time).

        If you just want a way to mirror static files, you'll want to look at rsync.

        And finally, as for S3, my personal opinion is to stay away.  I'm an SEO, but I also spent 7 years building a hosting company.  Those solutions sound great in their marketing, but are scientifically less reliable than standard hosting, and you can verify that via public uptime tracking sites like HyperSpin.

          Sitemap use for very large forum-based community site

          I work on a very large site with two main types of content, static landing pages for products, and a forum & blogs (user created) under each product. Site has maybe 500k - 1 million pages. We do not have a sitemap at this time.
          Currently our SEO discoverability in general is good, Google is indexing new forum threads within 1-5 days roughly. Some of the "static" landing pages for our smaller, less visited products however do not have great SEO.
          Question is, could our SEO be improved by creating a sitemap, and if so, how could it be implemented? I see a few ways to go about it: Sitemap includes "static" product category landing pages only - i.e., the product home pages, the forum landing pages, and blog list pages. This would probably end up being 100-200 URLs. Sitemap contains the above but is also dynamically updated with new threads & blog posts. Option 2 seems like it would mean the sitemap is unmanageably long (hundreds of thousands of forum URLs). Would a crawler even parse something that size? Or with Option 1, could it cause our organically ranked pages to change ranking due to Google re-prioritizing the pages within the sitemap?
          Not a lot of information out there on this topic, appreciate any input. Thanks in advance.

          Japanese URL-structured sitemap (pages) not being indexed by Bing Webmaster Tools

          Hello everyone, I am facing an issue with the sitemap submission feature in Bing Webmaster Tools for a Japanese language subdirectory domain project. Just to outline the key points: The website is based on a subdirectory URL ( example.com/ja/ ) The Japanese URLs (when pages are published in WordPress) are not being encoded. They are entered in pure Kanji. Google Webmaster Tools, for instance, has no issues reading and indexing the page's URLs in its sitemap submission area (all pages are being indexed). When it comes to Bing Webmaster Tools it's a different story, though. Basically, after the sitemap has been submitted ( example.com/ja/sitemap.xml ), it does report an error that it failed to download this part of the sitemap: "page-sitemap.xml" (basically the sitemap featuring all the sites pages). That means that no URLs have been submitted to Bing either. My apprehension is that Bing Webmaster Tools does not understand the Japanese URLs (or the Kanji for that matter). Therefore, I generally wonder what the correct way is to go on about this. When viewing the sitemap ( example.com/ja/page-sitemap.xml ) in a web browser, though, the Japanese URL's characters are already displayed as encoded. I am not sure if submitting the Kanji style URLs separately is a solution. In Bing Webmaster Tools this can only be done on the root domain level ( example.com ). However, surely there must be a way to make Bing's sitemap submission understand Japanese style sitemaps? Many thanks everyone for any advice!

          How does changing sitemaps affect SEO

          Hi all, I have a question regarding changing the size of my sitemaps. Currently I generate sitemaps in batches of 50k. A situation has come up where I need to change that size to 15k in order to be crawled by one of our licensed services. I haven't been able to find any documentation on whether or not changing the size of my sitemaps(but not the pages included in them) will affect my rankings negatively or my SEO efforts in general. If anyone has any insights or has experienced this with their site please let me know!

          Which Sitemap to keep - Http or https (or both)

          Hi, Just finished upgrading my site to the ssl version (like so many other webmasters now that it may be a ranking factor). FIxed all links, CDN links are now secure, etc and 301 Redirected all pages from http to https. Changed property in Google Analytics from http to https and added https version in Webmaster Tools. So far, so good. Now the question is should I add the https version of the sitemap in the new HTTPS site in webmasters or retain the existing http one? Ideally switching over completely to https version by adding a new sitemap would make more sense as the http version of the sitemap would anyways now be re-directed to HTTPS. But the last thing i can is to get penalized for duplicate content. Could you please suggest as I am still a rookie in this department. If I should add the https sitemap version in the new site, should i delete the old http one or no harm retaining it.

          Robots.txt and Multiple Sitemaps

          Hello, I have a hopefully simple question but I wanted to ask to get a "second opinion" on what to do in this situation. I am working on a clients robots.txt and we have multiple sitemaps. Using yoast I have my sitemap_index.xml and I also have a sitemap-image.xml I do put them in google and bing by hand but wanted to have it added into the robots.txt for insurance. So my question is, when having multiple sitemaps called out on a robots.txt file does it matter if one is before the other? From my reading it looks like you can have multiple sitemaps called out, but I wasn't sure the best practice when writing it up in the file. Example: User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /wp-admin/ Disallow: /wp-content/plugins/ Sitemap: http://sitename.com/sitemap_index.xml Sitemap: http://sitename.com/sitemap-image.xml Thanks a ton for the feedback, I really appreciate it! :) J

          Removing images from site and Image Sitemap SEO advice

          Hello again, I have received an update request where they want me to remove images from this site (as of now its a bunch of thumbnails) current page design: http://1stimpressions.com/portfolio/car-wraps/ and turn it into a new design which utilized a slider (such as this): http://1stimpressions.com/portfolio/ They don't want the thumbnails on the page anymore. My question is since my site has a image sitemap that has been indexed will removing all the images hurt my SEO greatly? What would the recommended steps to take to reduce any SEO damage be, if so? Thank you again for your help, always great and very helpful feedback! 🙂 cheers!

          302 redirect used, submit old sitemap?

          The website of a partner of mine was recently migrated to a new platform. Even though the content on the pages mostly stayed the same, both the HTML source (divs, meta data, headers, etc.) and URLs (removed index.php, removed capitalization, etc) changed heavily. Unfortunately, the URLs of ALL forum posts (150K+) were redirected using a 302 redirect, which was only recently discovered and swiftly changed to a 301 after the discovery. Several other important content pages (150+) weren't redirected at all at first, but most now have a 301 redirect as well. The 302 redirects and 404 content pages had been live for over 2 weeks at that point, and judging by the consistent day/day drop in organic traffic, I'm guessing Google didn't like the way this migration went. My best guess would be that Google is currently treating all these content pages as 'new' (after all, the source code changed 50%+, most of the meta data changed, the URL changed, and a 302 redirect was used). On top of that, the large number of 404's they've encountered (40K+) probably also fueled their belief of a now non-worthy-of-traffic website. Given that some of these pages had been online for almost a decade, I would love Google to see that these pages are actually new versions of the old page, and therefore pass on any link juice & authority. I had the idea of submitting a sitemap containing the most important URLs of the old website (as harvested from the Top Visited Pages from Google Analytics, because no old sitemap was ever generated...), thereby re-pointing Google to all these old pages, but presenting them with a nice 301 redirect this time instead, hopefully causing them to regain their rankings. To your best knowledge, would that help the problems I've outlined above? Could it hurt? Any other tips are welcome as well.

          How to handle sitemap with pages using query strings?

          Hi, I'm working to optimize a site that currently has about 5K pages listed in the sitemap.  There are not in face this many pages.  Part of the problem is that one of the pages is a tool where each sort and filter button produces a query string URL. It seems to me inefficient to have so many items listed that are all really the same page.  Not to mention wanting to avoid any duplicate content or low quality issues. How have you found it best to handle this?  Should I just noindex each of the links?  Canonical links? Should I manually remove the pages from the sitemap?  Should I continue as is? Thanks a ton for any input you have!
