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!

Thousands of 503 errors in GSC for pages not important to organic search - Is this a problem?
Hi, folks A client of mine now has roughly 30 000 503-errors (found in the crawl error section of GSC). This is mostly pages with limited offers and deals. The 503 error seems to occur when the offers expire, and when the page is of no use anymore. These pages are not important for organic search, but gets traffic from direct and newsletters, mostly. My question:
Intermediate & Advanced SEO | Aug 11, 2016, 9:43 AM | Inevo
Does having a high number of 503 pages reported in GSC constitute a problem in terms of organic ranking for the domain and the category and product pages (the pages that I want to rank for organically)? If it does, what is the best course of action to mitigate the problem? Looking excitingly forward to your answers to this 🙂 Sigurd0 -
Images Returning 404 Error Codes. 301 Redirects?
We're working with a site that has gone through a lot of changes over the years - ownership, complete site redesigns, different platforms, etc. - and we are finding that there are both a lot of pages and individual images that are returning 404 error codes in the Moz crawls. We're doing 301 redirects for the pages, but what would the best course of action be for the images? The images obviously don't exist on the site anymore and are therefore returning the 404 error codes. Should we do a 301 redirect to another similar image that is on the site now or redirect the images to an actual page? Or is there another solution that I'm not considering (besides doing nothing)? We'll go through the site to make sure that there aren't any pages within the site that are still linking to those images, which is probably where the 404 errors are coming from. Based on feedback below it sounds like once we do that, leaving them alone is a good option.

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 -
404 Errors with my RSS Feed/sitemap

XML Sitemap index within a XML sitemaps index
We have a similar problem to http://www.seomoz.org/q/can-a-xml-sitemap-index-point-to-other-sitemaps-indexes Can a XML sitemap index point to other sitemaps indexes? According to the "Unique Doll Clothing" example on this link, it seems possible http://www.seomoz.org/blog/multiple-xml-sitemaps-increased-indexation-and-traffic Can someone share an XML Sitemap index within a XML sitemaps index example? We are looking for the format to implement the same on our website.

How important is the number of indexed pages?
I'm considering making a change to using AJAX filtered navigation on my e-commerce site. If I do this, the user experience will be significantly improved but the number of pages that Google finds on my site will go down significantly (in the 10,000's). It feels to me like our filtered navigation has grown out of control and we spend too much time worrying about the url structure of it - in some ways it's paralyzing us. I'd like to be able to focus on pages that matter (explicit Category and Sub-Category) pages and then just let ajax take care of filtering products below these levels. For customer usability this is smart. From the perspective of manageable code and long term design this also seems very smart -we can't continue to worry so much about filtered navigation. My concern is that losing so many indexed pages will have a large negative effect (however, we will reduce duplicate content and be able provide much better category and sub-category pages). We probably should have thought about this a year ago before Google indexed everything :-). Does anybody have any experience with this or insight on what to do? Thanks, -Jason

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

Create a new XML Sitemap for a blog subdomain?
What would be the best way to go about this? A site just put a blog on http://blog.domain.com/ Should there be a separate XML Sitemap for that particular subdomain or should the original XML Sitemap for the main domain be sufficient? Looking forward to your responses. Thanks
