      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.

            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 🙂

            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

            Should I include URLs that are 301'd or only include 200 status URLs in my sitemap.xml?

            I'm not sure if I should be including old URLs (content) that are being redirected (301) to new URLs (content) in my sitemap.xml. Does anyone know if it is best to include or leave out 301ed URLs in a xml sitemap?

            Block in robots.txt instead of using canonical?

            When I use a canonical tag for pages that are variations of the same page, it basically means that I don't want Google to index this page. But at the same time, spiders will go ahead and crawl the page. Isn't this a waste of my crawl budget? Wouldn't it be better to just disallow the page in robots.txt and let Google focus on crawling the pages that I do want indexed? In other words, why should I ever use rel=canonical as opposed to simply disallowing in robots.txt?

            Is Using a Question, Answer Format Appropriate for a Blog? Is a 300 Word Micro Blog An SEO Plus?

            My PR agency has suggested a question answer format be incorporated in my blog. They suggest a microblog with a single sentence question and an answer of about 300 words. My blog currently has about 35 posts. I would like to ramp up blog entries to about one or two per week of these "mini blog" posts. The format of the new blog begins as a question with the responses being paragraphs that do not use headings. My concerns are as follows: 1. No headings in an answer of 300 words will fail to provide Google with context regarding the content's meaning. Everything I have read about SEO suggests text be broken up in short sections and that it be divided by headings (preferably H2s). I very much like my agency's concept for a question answer format blog. It provides very practical info for visitors. How can I use it in a manner that supports SEO best practices? 2. According to a reputable SEO firm that has been assisting me, Google does not consider a blog post of less than 600 words to be superior quality. They told me that  blog posts of 300 words, from an SEO purpose will not be a great helpful, that the content will not be rich enough to generate incoming links. Is this really the case? What if this abbreviated content is very well written and engaging? If so, is 300 words sufficient? From the visitor's perspective I am not sure they would have the patience to read 600 words when 300 words is more than than enough to answer these basic questions. From a PR perspective I think the shorter content in a question answer format is superior at least for my line of business (commercial real estate brokerage). 3. If 500-600 words is the minimum word count, and headings are necessary, what is the best way to execute a question and answer blog format? The purpose of this blog is to provide very useful info to my visitors while generating incoming links to that will boast my rankings. Thanks in advance for your feedback!!! Alan

            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. Thanks

            How does badly formatted HTML affect SEO?

            Our website uses a custom built CMS, but uses a fairly standard WYSIWYG text editor. I've looked at some of the code it produces, and it's not pretty. My gut feeling tells me that this extra bloat is bad for SEO. Am I right in thinking that Google doesn't look kindly upon badly formatted and bloated HTML? Thanks,
            James

            Submitting URLs multiple times in different sitemaps

            We have a very dynamic site, with a large number of pages. We use a sitemap index file, that points to several smaller sitemap files. The question is: Would there be any issue if we include the same URL in multiple sitemap files? Scenario: URL1 appears on sitemap1. 2 weeks later, the page at URL1 changes and we'd like to update it on a sitemap. Would it be acceptable to add URL1 as an entry in sitemap2?  Would there be any issues with the same URL appearing multiple times? Thanks.
