When I alter and re-submit a sitemap does GWTs immediately re-evaluate it or do I have to wait 'til GoogleBot crawls our site again?

I just re-submitted a problematic sitemap and it now displays the green tick next to it but does this really mean it is valid? I need to know is the problem really solved.


Google Webmaster Central says:

"Once you've reviewed your Sitemap and made any changes, save it and then resubmit it. It can take up to a day for Google to process the resubmitted Sitemap, so the warning status may continue to display until then."

I would use this to answer the question, but does this actually mean that my problem is gone? (Because the icon changes from a red X (error) to a green tick (valid)).
I'm not so sure.
I simply resubmitted one problematic sitemap without any changes and the icon changed.


On the details page of a problematic sitemap I re-submitted, the Downloaded date is today's that. Does this guarantee the error was fixed? Because the Downloaded date is today for both sitemaps I re-submitted (see edit #1)

I'd suggest you use this tool to create your sitemap if you don't already. Download the uncompressed xml one and put it at the root of your domain.

Now, when it comes to re-evaluating sitemaps, GWT does it almost instantaneously when you re-submit it, but for the changes to actually be taken into account by the internet as a whole, you'll have to wait till Google recrawls your site, yes.

Anybody feel free to correct me if I'm wrong, but I think that's how it goes ;)

I have a site with over 300,000 links and 30 different site maps. I found that, after I change my site maps and resubmit, Google continued to crawl my site using the old site maps for a few days.

I had a major issue involving double urlencoding as stated here

On the first day, Google gave me over 1000 errors involving urlencoding. I fixed the problem and resubmitted my site maps, but for two days, the errors kept coming. I had to continually mark errors as fixed and eventually the errors stopped coming.

There is lag time, so be sure to make you sitemaps a accurate as possible the first time and wait a day or two before judging the effects of an update
