      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.

            Hreflang in header...should I do a Sitemap?

            A client implemented hreflang tags in the site header. MOZ says you aren't supposed to do an hreflang Sitemap as well. My question is how should I do a Sitemap now (or should I do one at all)?

            Sitemaps during a migration - which is the best way of dealing with them?

            Many SEOs I know simply upload the new sitemap once the new site is launched - some keep the old site's URLs on the new sitemap (for a while) to facilitate the migration - others upload both the old and the new website together, to support the migration. Which is the best way to proceed? Thanks, Luke

            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?

            404 Errors with my RSS Feed/sitemap

            In my google webmasters I just started getting 404 errors that I'm not sure how to redirect. I'm getting quite a few that are ending in /feed/ for instance /nyc-accident-injury/feed/
            contact-us-thank-you/feed/ and then also a problem with my sitemap I guess? With /site-map/?postsort=tags The domain is pulversthompson.com

            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.

            All page files in root? Or to use directories?

            We have thousands of pages on our website; news articles, forum topics, download pages... etc - and at present they all reside in the root of the domain /. For example: /aosta-valley-i6816.html
            /flight-sim-concorde-d1101.html
            /what-is-best-addon-t3360.html We are considering moving over to a new URL system where we use directories.  For example, the above URLs would be the following: /images/aosta-valley-i6816.html
            /downloads/flight-sim-concorde-d1101.html
            /forums/what-is-best-addon-t3360.html Would we have any benefit in using directories for SEO purposes?  Would our current system perhaps mean too many files in the root / flagging as spammy?  Would it be even better to use the following system which removes file endings completely and suggests each page is a directory: /images/aosta-valley/6816/
            /downloads/flight-sim-concorde/1101/
            /forums/what-is-best-addon/3360/ If so, what would be better: /images/aosta-valley/6816/ or /images/6816/aosta-valley/ Just looking for some clarity to our problem! Thank you for your help guys!

            Sitemap in SERPS

            What's up guys, Having some troubles with SERP rankings. My sitemap (navigation) is appearing instead of my actual keywords. I have tried a few methods to fix this; setting a preferred domain, using a 301 redirects, deleting out of date pages via Google webmaster tools. Nothing seems to work. My next step was to refresh the cache for my entire site - does anyone know how to do this? Can't see any tools... Any help would be great. Cheers, Jon.
