How important are sitemap errors?
-
If there aren't any crawling / indexing issues with your site, how important do thing sitemap errors are? Do you work to always fix all errors?
I know here: http://www.seomoz.org/blog/bings-duane-forrester-on-webmaster-tools-metrics-and-sitemap-quality-thresholds
Duane Forrester mentions that sites with many 302's 301's will be punished--does any one know Googe's take on this?
-
Very important. Particularly if you have a large site. We operate a large site with 100,000's of pages and as Dan said it can be difficult to maintain. We use something called Unlimited XML Sitemap Generator which builds XML sitemaps for us automatically. I'd highly recommend it although it takes a bit of fiddling with to get it up and running as it's software which sits on site. We couldn't manage without it as we'd be forever on sitemaps.
We found that getting sitemaps right on a large site made a huge difference to the crawl rate that we encountered in GWT and a huge indexation to follow.
In particular check for 302's. I made the mistake of leaving those for a while and am sure that we suffered from some loss of link equity along the way.
Hope it helps

Your sitemap should only list pages that actually exist.
If you delete some pages, then you need to rebuild the sitemap.
Ditto if you delete them and redirect.
Google is always lagging, so if you delete 10 pages and then update the sitemap, even if google downloads the sitemap immediately, they will still be running crawls on the old map, and they may be crawling the now-missing pages, but haven't shown the failures in your WMT yet.
If you update your sitemap quickly, it is possible they will never crawl the missing pages and get a 404 or 301.
(but of course, there could be other sites pointing to the now-missing pages, and the 404s will show up elsewhere as missing)
I am always checking, adding, deleting and redirecting pages, and I update the current sitemap every hour and all the others are rebuilt at midnight every night. I usually do deletions just before midnight if I can, to minimize the time the sitemap is out of sync.

As far as I know Google is more lenient with sitemap errors, but I would still recommend looking into it. The first step would be to be sure your sitemap is up to date to begin with - and has all the URLs you want (and not any you don't want). The main thing is none of them should 404 and then beyond that, yes, they should return 200's.
Unless you're dealing with a gigantic site which might be hard to maintain, in theory there shouldn't be errors in sitemaps if you have the correct URLs in there.
Even better, if you're running WordPress the Yoast SEO plugin will generate an XML sitemap for you and it update automatically.
Hope that helps!

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?

Substantial difference between Number of Indexed Pages and Sitemap Pages
Hey there, I am doing a website audit at the moment. I've notices substantial differences in the number of pages indexed (search console), the number of pages in the sitemap and the number I am getting when I crawl the page with screamingfrog (see below). Would those discrepancies concern you? The website and its rankings seems fine otherwise. Total indexed: 2,360 (Search Consule)
Intermediate & Advanced SEO | Nov 5, 2015, 6:10 PM | Online-Marketing-Guy
About 2,920 results (Google search "site:example.com")
Sitemap: 1,229 URLs
Screemingfrog Spider: 1,352 URLs Cheers,

Is it a problem to use a 301 redirect to a 404 error page, instead of serving directly a 404 page?
We are building URLs dynamically with apache rewrite.
Intermediate & Advanced SEO | Aug 13, 2014, 11:11 AM | lcourse
When we detect that an URL is matching some valid patterns, we serve a script which then may detect that the combination of parameters in the URL does not exist. If this happens we produce a 301 redirect to another URL which serves a 404 error page, So my doubt is the following: Do I have to worry about not serving directly an 404, but redirecting (301) to a 404 page? Will this lead to the erroneous original URL staying longer in the google index than if I would serve directly a 404? Some context. It is a site with about 200.000 web pages and we have currently 90.000 404 errors reported in webmaster tools (even though only 600 detected last month).0 -
What are partial urls and why this is causing a sitemap error?
Hi mozzers, I have a client that recorded 7 errors when generating Xml sitemap. One of the errors appear to be coming from partial urls and apparently I would need to exclude them from sitemap. What are they exactly and why would they cause an error in the sitemap. Thanks!

Xml sitemap advice for website with over 100,000 articles
Hi, I have read numerous articles that support submitting multiple XML sitemaps for websites that have thousands of articles... in our case we have over 100,000. So, I was thinking I should submit one sitemap for each news category. My question is how many page levels should each sitemap instruct the spiders to go? Would it not be enough to just submit the top level URL for each category and then let the spiders follow the rest of the links organically? So, if I have 12 categories the total number of URL´s will be 12??? If this is true, how do you suggest handling or home page, where the latest articles are displayed regardless of their category... so I.E. the spiders will find l links to a given article both on the home page and in the category it belongs to. We are using canonical tags. Thanks, Jarrett
