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.

How important is the file extension in the URL for images?
I know that descriptive image file names are important for SEO. But how important is it to include .png, .jpg, .gif (or whatever file extension) in the url path? i.e. https://example.com/images/golden-retriever vs. https://example.com/images/golden-retriever.jpg Furthermore, since you can set the filename in the Content-Disposition response header, is there any need to include the descriptive filename in the URL path? Since I'm pulling most of our images from a database, it'd be much simpler to not care about simulating a filename, and just reference an image id in my templates. Example: 1. Browser requests GET /images/123456

2. Server responds with image setting both Content-Disposition, and Link (canonical) headers Content-Disposition: inline; filename="golden-retriever"
Link: <https: 123456="" example.com="" images="">; rel="canonical"</https:>1 -
This url is not allowed for a Sitemap at this location error using pro-sitemaps.com
Hey, guys, We are using the pro-sitemaps.com tool to automate our sitemaps on our properties, but some of them give this error "This url is not allowed for a Sitemap at this location" for all the urls. Strange thing is that not all of them are with the error and most have all the urls indexed already. Do you have any experience with the tool and what is your opinion? Thanks

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

Is using dots in URL path really a problem?
we have a couple of pages displaying a dot in the URL path like domain.com/mr.smith/widget-mr.smith It displays fine in chrome, firefox and IE and for the user it may actually look better than replacing it by _ or -. Did this ever cause problems to anybody?

Any statement from google about it?
Should I change existing URLs? If so, which other characters can I use in the URL instead of underscore and dash, since in our system dash and underscore are already used for rewriting other characters. Thanks0 -
Getting a Sitemap for a Subdomain into Webmaster Tools
We have a subdomain that is a Wordpress blog, and it takes days, sometimes weeks for most posts to be indexed. We are using the Yoast plugin for SEO, which creates the sitemap.xml file. The problem is that the sitemap.xml file is located at blog.gallerydirect.com/sitemap.xml, and Webmaster Tools will only allow the insertion of the sitemap as a directory under the gallerydirect.com account. Right now, we have the sitemap listed in the robots.txt file, but I really don't know if Google is finding and parsing the sitemap. As far as I can tell, I have three options, and I'd like to get thoughts on which of the three options is the best choice (that is, unless there's an option I haven't thought of): 1. Create a separate Webmaster Tools account for the blog 2. Copy the blog's sitemap.xml file from blog.gallerydirect.com/sitemap.xml to the main web server and list it as something like gallerydirect.com/blogsitemap.xml, then notify Webmaster Tools of the new sitemap on the galllerydirect.com account 3. Do an .htaccess redirect on the blog server, such as RewriteRule ^sitemap.xml http://gallerydirect.com/blogsitemap_index.xml Then notify Webmaster Tools of the new blog sitemap in the gallerydirect.com account. Suggestions on what would be the best approach to be sure that Google is finding and indexing the blog ASAP?
