301 forwarding old urls to new urls - when should you update sitemap?
-
Hello Mozzers,
If you are amending your urls - 301ing to new URLs - when in the process should you update your sitemap to reflect the new urls?
I have heard some suggest you should submit a new sitemap alongside old sitemap to support indexing of new URLs, but I've no idea whether that advice is valid or not.
Thanks in advance, Luke

Hi Luke
To include the suggestion on searchenginewatch.com in this conversation, it said:
Submit an updated sitemap to Google Webmaster tools and use the change of address function if moving to a new domain. Remember to initially keep the old URLs in your XML sitemap to facilitate Google crawling those links and processing the changes in their index.
Well it would be interesting to hear others feedback on that. Personally, I think having old URLs in a sitemap (that without a redirect would result in a page not found 404 error) doesn't seem correct to me.
Presumably, you have had the URL in the sitemap previously when the page at the URL was active. But then, by setting up a 301 redirect, you are telling Google that the page at the URL that Google has in its index has now permanently moved to a new URL.
When you submit a sitemap to Google then you are submitting a list of all the URLs on your site that you are asking Google to crawl. But to include the old URL in your sitemap along with the new URL is essentially asking Google to crawl two URLs pointing to the same page.
I'm not sure Google would necessarily consider that to be a canonical issue (because the old URL is now not current) but for me it's a misuse of the sitemap.
But as I say, it would be interesting to hear others feedback on this.

Thanks Peter - I note here:

Here it's suggested that sites keep old URLs in their sitemaps. I've heard others suggest otherwise. Seems to be a fair bit of conflicting advice out there.

Hi Luke
My advice would be that you submit one the sitemap containing the new URLs. The new sitemap should contain the new URLs and replace the old sitemap.
The 301 redirects are for the purpose of redirecting outdated links and search engine indexes to the new 301 (permanent) URLs and should remain in place even when search engines have updated their indexes so that they always redirect any outdated backlinks.
I hope that helps,
Peter

How much does URLs with CAPS and URLs with non-CAPS existing on an IIS site matter nowadays?
I work on a couple ecommerce sites that are on IIS. Both sites have return a 200 header status for the CAPS and non CAPS version of the URLs. While I suppose it would be ok if the canonicals pointed to the same version of the page, in some cases it doesn't (ie; /Home-Office canonicalizes to itself and /home-office canonicalizes to itself). I came across this article (http://www.searchdiscovery.com/blog/case-sensitive-urls-and-seo-case-matters/) that is a few years old and I'm wondering how much of an issue it is and how I would determine if it is/isn't?

Multiple Sitemaps Vs One Sitemap and Why 500 URLs?
I have a large website with rental listings in 14 markets, listings are added and taken off weekly if not daily. There are hundreds of listings in each market and all have their own landing page with a few pages associated. What is the best process here? I could run one sitemap and make each market's landing page .8 priority in the sitemap or make 14 sitemaps for each market and then have one sitemap for the general and static pages. From there, what would be the better way to structure? Should I keep all the big main landing pages in the general static sitemap or have them be at the top of the market segmented sitemaps? Also, I have over 5,000 urls, what is the best way to generate a sitemap over 500 urls? Is it necessary?

Moving to a new site while keeping old site live
For reasons I won't get into here, I need to move most of my site to a new domain (DOMAIN B) while keeping every single current detail on the old domain (DOMAIN A) as it is. Meaning, there will be 2 live websites that have mostly the same content, but I want the content to appear to search engines as though it now belongs to DOMAIN B. Weird situation. I know. I've run around in circles trying to figure out the best course of action. What do you think is the best way of going about this? Do I simply point DOMAIN A's canonical tags to the copied content on DOMAIN B and call it good? Should I ask sites that link to DOMAIN A to change their links to DOMAIN B, or start fresh and cut my losses? Should I still file a change of address with GWT, even though I'm not going to 301 redirect anything?

Moving career site to new URL from main site. Will it hurt SEO for main page?
For one of our clients we are building a career site and putting it under a different URL and hosting service (mainly due to security concerns of hosting it under the same host and domain). almost 100% of the incoming traffic to their current career section (which it is in a sub-folder) receives traffic for branded keywords (brand + job/career/employment), that is, there are no job position specific keywords. The client is now worried that after moving the site, the inbound traffic to the main site will be severely affected as well as the SERP results. My questions are, will the non-career related SERPs be affected? I don't see how will they be but I could be wrong If no, how could we reassure her that the SEO to the main site wont be affected? are there any case studies of a similar case (splitting part of the website under a new URL and hosting service?) Thank you for your help. PS: this is my first post so please forgive me if this has been asked before. I could not find a good response.

Received "Googlebot found an extremely high number of URLs on your site:" but most of the example URLs are noindexed.
An example URL can be found here: http://symptom.healthline.com/symptomsearch?addterm=Neck%20pain&addterm=Face&addterm=Fatigue&addterm=Shortness%20Of%20Breath A couple of questions: Why is Google reporting an issue with these URLs if they are marked as noindex? What is the best way to fix the issue? Thanks in advance.

http://www.gigantic.com/leefest-2013/highhams-hill-farm/2013-07-12-12-00 my question is: Is it better to leave the old event pages active and link them back to the main page, or 301 redirect these pages once they're out of date? (leave them there until there is a new event page to replace it for this year) If the best answer is to leave the page there, should i use a canonical tag back to the main page? and what would be the best way to link back? there is a breadcrumb there now, but it doesn't seem to obvious for users to click this. Keywords we're aming for on this example are 'Leefest Tickets', which has good ranking now, the main page and 2012 page is listed. Thanks in advance for your help.0
