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!

Do you suggest I use the Yoast or the Google XML sitemap for my blog?
I just shut off the All-In-One seo pack plugin for wordpress, and turned on the Yoast plugin. It's great! So much helpful, seo boosting info! So, in watching a video on how to configure the plugin, it mentions that I should update the sitemap, using the Yoast sitemap I'm afraid to do this, because I'm pretty technologically behind... I see I have a Google XML Sitemaps (by Arne Brachhold) plugin turned on (and have had it for many years). Should I leave this one on? Or would you recommend going through the steps to use the Yoast plugin sitemap? If so, what are the benefits of the Yoast plugin, over the Google XML? Thanks!

Should pages with rel="canonical" be put in a sitemap?
I am working on an ecommerce site and I am going to add different views to the category pages. The views will all have different urls so I would like to add the rel="canonical" tag to them. Should I still add these pages to the sitemap?

Hreflang in vs. sitemap?
Hi all, I decided to identify alternate language pages of my site via sitemap to save our development team some time. I also like the idea of having leaner markup. However, my site has many alternate language and country page variations, so after creating a sitemap that includes mostly tier 1 and tier 2 level URLs, i now have a sitemap file that's 17mb. I did a couple google searches to see is sitemap file size can ever be an issue and found a discussion or two that suggested keeping the size small and a really old article that recommended keeping it < 10mb. Does the sitemap file size matter? GWT has verified the sitemap and appears to be indexing the URLs fine. Are there any particular benefits to specifying alternate versions of a URL in vs. sitemap? Thanks, -Eugene

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 | | 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 -
Should I redirect my xml sitemap?
Hi Mozzers, We have recently rebranded with a new company name, and of course this necessitated us to relaunch our entire website onto a new domain. I watched the Moz video on how they changed domain, copying what they did pretty much to the letter. (Thank you, Moz for sharing this with the community!) It has gone incredibly smoothly. I told all my bosses that we may see a 40% reduction in traffic / conversions in the short term. In the event (and its still very early days) we have in fact seen a 15% increase in traffic and our new website is converting better than before so an all-round success! I was just wondering if you thought I should redirect my XML sitemap as well? So far I haven't, but despite us doing the change of address thing in webmaster tools, I can see Google processed the old sitemap xml after we did the change of address etc. What do you think? I know we've been very lucky with the outcome of this rebrand but I don't want to rest on my laurels or get tripped up later down the line. Thanks everyone! Amelia

Should sitemap include https pages?
Hi guys, Trying to figure out some onsite issues I've been having. Would appreciate any feedback on the following 2 questions: My homepage (http://mysite.com) is a 301 redirect to https://mysite.com, which is under SSL. Only 2 pages of my site are https, the rest are http. Should the directory of my sitemap be https://mysite.com/sitemap.xml or should it be kept with http (even though the redirected homepage is to https)? Should my sitemap include the https pages (only 2 pages) as well as the http? Thanks, G

Using WP All Import csv import plugin for wordpress to daily update products on large ecommerce site. Category naming and other issues.
We have just got an automated solution working to upload about 4000 products daily to our site. We get a CSV file from the wholesalers server each day and the way they have named products and categories is not ideal. Although most of the products remain the same (don't need to be over written) Some will go out of stock or prices may change etc. Problem is we have no control over the csv file so we need to keep the catagories they have given us. Might be able to create new catgories and have products listed under multiple categories? If anyone has used wp all import or has knoledge in this area please let me know. I have plenty more questions but this should start the ball rolling! Thanks in advance mozzers

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
