Sitemaps. When compressed do you use the .gz file format or the (untidy looking, IMHO) .xml.gz format?
-
When submitting compressed sitemaps to Google I normally use the a file named sitemap.gz
A customer is banging on that his web guy says that sitemap.xml.gz is a better format.
Google spiders sitemap.gz just fine and in Webmaster Tools everything looks OK...
Interested to know other SEOmoz Pro's preferences here and also to check I haven't made an error that is going to bite me in the ass soon!
Over to you.

Thanks Big Bazza... I like the 'better' vs 'accepted' reasoning. Not too confrontational

-
Generally the .xml.gz format is the one stated in examples there are a few references to this here : http://www.sitemaps.org/protocol.php#index
Most sitemap generators that create both compressed and uncompressed sitemap files name them sitemap.xml and sitemap.xml.gz respectively. It also makes it clearer what the content of the zipped file is. I don't believe it is essential however, as you will direct tools such as google.com/webmasters to your xml sitemap - rather than expect it to find it of its own accord.
I always use the .xml.gz format when compressing. I would argue that (if both formats work) neither one is 'BETTER' than the other, rather one is more ACCEPTED than the other.

Unsolved How much time does it take for Google to read the Sitemap?
Hi there, I could use your help with something. Last week, I submitted my sitemap in the search console to improve my website's visibility on Google. Unfortunately, I got an error message saying that Google is not reading my sitemap. I'm not sure what went wrong. Could you take a look at my site (OceanXD.org) and let me know if there's anything I can do to fix the issue? I would appreciate your help. Thank you so much!

URL structure change and xml sitemap
At the end of April we changed the url structure of most of our pages and 301 redirected the old pages to the new ones. The xml sitemaps were also updated at that point to reflect the new url structure. Since then Google has not indexed the new urls from our xml sitemaps and I am unsure of why. We are at 4 weeks since the change, so I would have thought they would have indexed the pages by now. Any ideas on what I should check to make sure pages are indexed?

Does anyone know of any tools that can help split up xml sitemap to make it more efficient and better for seo?
Hello All, We want to split up our Sitemap , currently it's almost 10K pages in one xml sitemap but we want to make it in smaller chunks splitting it by category or location or both. Ideally into 100 per sitemap is what I read is the best number to help improve indexation and seo ranking. Any thoughts on this ? Does anyone know or any good tools out there which can assist us in doing this ? Also another question I have is that should we put all of our products (1250) in one site map or should this also be split up in to say products for category etc etc ? thanks Pete

How to track mentions with links using Mentions App
We have a large client that we've just taken on board for organic search marketing. A great client that continually gets links from the BBC, NY Times etc which actually takes care of having to do any marketing for them. However, they get 10-15 unlinked mentions per day. Just recently, they peaked at 32 mentions in one day from JUST websites. But I need a quick way to filter these out and check if there is a link pointing to their website. I want to be able to build up a list of opportunities without having to manually check each website. How do, Mozzlars!?

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

XML Sitemap for classifieds
I have seeon some trends for sites which do not even use XML sitemp and robots e.g. see this site. How do you see if sitemap is not used. Also for classified websites, should ad pages be included in sitemap because after certain duration those ads will be deleted and google might not be able to crawl. What do you suggest about XML sitemap for classified website.

Canonical & noindex? Use together
For duplicate pages created by the "print" function, seomoz says its better to use noindex (http://www.seomoz.org/blog/complete-guide-to-rel-canonical-how-to-and-why-not) and JohnMu says its better to use canonical http://www.google.com/support/forum/p/Webmasters/thread?tid=6c18b666a552585d&hl=en What do you think?
