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 safe is it to use a meta-refresh to hide the referrer?
Hi guys, So I have a review site and I'm affiliated with several partnership programs whose products I advertise on my site. I don't want these affiliate programs to see the source of my traffic (my site), so I'm looking for a safe solution to hide the referrer URL. I have recently added a rel="noreferrer" tag to all my affiliate links, but this method isn't perfect as not all browsers respect that rule. After doing some research and checking my competitors I noticed that some of them use meta-refresh, which seems more reliable in this regard. So, how safe is it to use meta-refresh as means of hiding referrer URL? I'm worrying that implementing a meta-refresh redirect might negatively affect my SEO. Does anybody have any suggestions on how to hide the referrer URL without damaging SEO? Thank you.

Sitemaps: Best Practice
What should and what shouldn't go in the sitemap? In particular, pages like subscribe to our newsletter/ unsubscribe to our newsletter? Is there really any benefit in highlighting those pages to the SEs? Thanks for any advice/ anecdotes 🙂

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

Is it worth creating an Image Sitemap?
We've just installed the server side script 'XML Sitemaps' on our eCommerce site. The script gives us the option of (easily) creating an image sitemap but I'm debating whether there is any reason for us to do so. We sell printer cartridges and so all the images will be pretty dry (brand name printer cartridge in front of a box being a favourite). I can't see any potential customers to search for an image as a route in to the site and Google appears to be picking up our images on it's own accord so wonder if we'll just be crawling the site and submitting this information for no real reason. From a quality perspective would Google give us any kind of kudos for providing an Image Sitemap? Would it potentially increase their crawl frequency or, indeed, reduce the load on our servers as they wouldn't have to crawl for all the images themselves?

I can't stress how little of a hardship it will be to create one of these automatically daily but am wondering if, like Meta Keywords, there is any benefit to doing so?1 -
Best server-side sitemap generators
I've been looking into sitemap generators recently and have got a good knowledge of what creating a sitemap for a small website of below 500 URLs involves. I have successfully generated a sitemap for a very small site, but I’m trying to work out the best way of crawling a large site with millions of URLs. I’ve decided that the best way to crawl such a large number of URLs is to use a server side sitemap, but this is an area that doesn’t seem to be covered in detail on SEO blogs / forums. Could anyone recommend a good server side sitemap generator? What do you think of the automated offerings from Google and Bing? I’ve found a list of server side sitemap generators from Google, but I can’t see any way to choose between them. I realise that a lot will depend on the type of technologies we use server side, but I'm afraid that I don't know them at this time.

When using ALT tags - are spaces, hyphens or underscores preferred by Google when using multiple words?
when plugging ALT tags into images, does Google prefer spaces, hyphens, or underscores? I know with filenames, hyphens or underscores are preferred and spaces are replaced with %20. Thoughts? Thanks!

Can a XML sitemap index point to other sitemaps indexes?
We have a massive site that is having some issue being fully crawled due to some of our site architecture and linking. Is it possible to have a XML sitemap index point to other sitemap indexes rather than standalone XML sitemaps? Has anyone done this successfully? Based upon the description here: http://sitemaps.org/protocol.php#index it seems like it should be possible. Thanks in advance for your help!
