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.

Should I use the on classified listing pages that have expired?
We have went back and forth on this and wanted to get some outside input. I work for an online listing website that has classified ads on it. These ads are generated by companies on our site advertising weekend events around the country. We have about 10,000 companies that use our service to generate their online ads. This means that we have thousands of pages being created each week. The ads have lots of content: pictures, sale descriptions, and company information. After the ads have expired, and the sale is no longer happening, we are currently placing the in the heads of each page. The content is not relative anymore since the ad has ended. The only value the content offers a searcher is the images (there are millions on expired ads) and the descriptions of the items for sale. We currently are the leader in our industry and control most of the top spots on Google for our keywords. We have been worried about cluttering up the search results with pages of ads that are expired. In our Moz account right now we currently have over 28k crawler warnings alerting us to the being in the page heads of the expired ads. Seeing those warnings have made us nervous and second guessing what we are doing. Does anybody have any thoughts on this? Should we continue with placing the in the heads of the expired ads, or should we be allowing search engines to index the old pages. I have seen websites with discontinued products keeping the products around so that individuals can look up past information. This is the closest thing have seen to our situation. Any help or insight would be greatly appreciated! -Matt

Href lang in image or video XML sitemaps
Does anyone know if it is possible/recommended/not recommended to use href lang in image or video XML sitemaps? This had not crossed my mind until recently, but a client asked me this question and I couldn't find any information on this topic.

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?

Using pictures from another domain
We are building several sites for several clients which will be using images from the manufacturer. Our dev team wants to insert the manufacturer's url for the images, instead of actually downloading the image and hosting on our server. There are thousands of images, so downloading images to our server will be time consuming, so we are looking for a shortcut.... however I'm concerned this will cause other issues. Is using manufactueresdomain.com/12345.jpg going to cause SEO issues? will this generate Google penalties? Since we are not able to control the image file name, we cannot optimize it. We will add Alt text and Title tag for each image, but the file name is random characters. How important is the file name for SEO?

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

Use of subdomains, subdirectories or both?
Hello, i would like your advice on a dilemma i am facing. I am working a new project that is going to release soon, thats a network of users with personal profiles seperated in categories for example lets say the categories are colors. So let say i am a member and i belong in red color categorie and i got a page where i update my personal information/cv/resume as well as a personal blog thats on that page. So the main site is giving the option to user to search for members by the criteria of color. My first idea is that all users should own a subdomain (and this is how its developed so far) thats easy to use and since the domain name is really small (just 3 letters) i believe subdomain worth since personal site will be easy to remember. My dilemma is should all users own a subdomain, a subdirectory or both and if both witch one should be the canonical? Since it said that search engines treat subdomains as different stand-alone sites, whats best for the main site? to show multiple search results with profiles in subdomains or subdirectories? What if i use both? meaning in search results i use search directory url for each profile while same time each profile owns a subdomains as well? and if so which one should be the canonical? Thanks in advance, C

Using 2 wildcards in the robots.txt file
I have a URL string which I don't want to be indexed. it includes the characters _Q1 ni the middle of the string. So in the robots.txt can I use 2 wildcards in the string to take out all of the URLs with that in it? So something like /_Q1. Will that pickup and block every URL with those characters in the string? Also, this is not directly of the root, but in a secondary directory, so .com/.../_Q1. So do I have to format the robots.txt as //_Q1* as it will be in the second folder or just using /_Q1 will pickup everything no matter what folder it is on? Thanks.
