Redirects in site map
-
I have a site with the ace/sef ( creates friendly URLS) in a large data base site.
It creates a site map dynamically.
Yet I realize one issue which I am trying to think through.
I recently changed my urls to include an ID number
example: homepage/houses/1134-big-blue-house
The prior url was: homepage/houses/big-blue-house
the original url above redirects to the new one with the ID like I want.
However the site map has both URLS in it which go to same page
I am not sure but it seems rather stupid to have the new URL and OLD redirected URL in the site map. Yet beside stupid I am wondering if this is duplicate content and will cause a penalty from the google bot.
What is your opinion ?

Howdy,
Actually, in the short-term, it may be beneficial to list both in your sitemap.
The reason for this is that you want search engines to try and crawl the "old" url to process the 301 that it finds there. The quicker they visit the old URL, the faster they will realize the page is redirecting, and this actually will reduce any perceived duplicated content issues on the part of the search engines.
Generally, you would do this with 2 sitemaps - one with the old URLs and one listing the new, and submit them both to Google via Webmaster Tools. You would leave the old one in place for 30 days before removing it.
After 30 days, however, it's best to use a single sitemap with only one set of URLs. As Ben mentioned, you don't want search engines wasting crawling resources on forever trying to visit URLs that redirect.
So after a time, it would be best to remove the old URLs from the sitemap. Unfortunately, I'm not familiar with the AceSEF Joomla package, but I believe there is a way to configure it to remove those URLs - even if manually according to the feature set: http://www.joomace.net/blog/xmap-joomap-sef-sm-2-and-acesef
Hope this helps! Best of luck with your SEO.

I would not be afraid of duplicate content more than I would be afraid of diminishing value of your site's focus because the bot is wasting resources on the 301's.

Subdomain redirect
Hey guys, I was thinking about creating subdomains for one of my websites. I want to divide my website in different subdomains (blog.[site].com / directory.[site].com / etc.) but I'm afraid that this will negatively impact my rankings. My blog for example has a lot of supporting content for my products and services that are primarily hosted on the homepage. Have you guys ever created subdomains at a later stage of your website's existence? What kind of impact did you notice? Would you recommend it? Thanks a million!

Google indexing staging / development site that is redirected...
Hi Moz Fans! - Please help. We had a acme.stagingdomain.com while a site was in development, when it went live it redirected (302) to acmeprofessionalservices.com (real names redacted!!) no known external links to staging site although staging site url has been emailed from Google Apps(!!!) now found that staging site is in the index even though it redirects to the proper public site. and some (but not all) of the pages are in the index too. They all redirect to the proper public site when visited. It is convenient to have a redirect from the staging site to the new one for the team, Chrome etc. remember frequently visited sites. Be a shame to lose that. Yes, these pages can be removed using webmaster tools.

But how did they get in the index to start with? And if we're building a new site, and a customer has an existing site is there a danger of duplicate content etc. penalties caused by the staging site? We had a similar incident recently when a PDF that was not linked anywhere on the site appeared in the index. The link had been emailed through Google Apps, and visited in Chrome, but that was it. So 3 questions. Why is the staging site still in the index despite the redirects? How did they get in the index in the first place? Will the new staging site affect the rank of the existing site, eg. duplicate content penalties?0 -
Linking shallow sites to flagship sites
We have hundreds of domains that we are either doing nothing with, or they are very shallow. We do not have the time to build enough quality content on them since they are ancillary to our flagship sites that are already in need of attention and good content. My question is...should we redirect them to the flagship site? If yes, is it ok to do this from root domain to root domain or should we link the root domain to a matching/similar page (gymfranchises.com to http://www.franchisesolutions.com/health_services_franchise_opportunities.cfm)? Or should we do something different altogether? Since we have many to redirect (if this is the route we go), should we redirect gradually?

301 redirects and seo..
I bought a domain and it has nice traffic. It only has about 5 main pages in php When i got the site i switched to html because php was overkill. I did the 301 and google deleted the php files and replaced with html version when i check site:domain.com It has been about 7 days. I DID NOT use 301 for each of the 5 pages to go php to html instead is used this code RewriteEngine On

RewriteCond %{HTTP_HOST} ^mydomain.com
RewriteRule (.) http://www.mydomain.com/$1 [R=301,L]
RedirectMatch 301 (.).php$ http://www.mydomain.com$1.html So basically if you load php it will load the html version. dog.php > dog.html Is this OKAY? or should it be done differently.... worried! Thanks !0 -

Redirecting Parked Domain
I just recently switched hosting. We have 3 domains and 1 being the main domain. Right now they are set up as parked domains. Can I redirect the parked domains under my main websites .htaccess file ? I am just worried that good we will get hit for duplicate content, even though technically the content is only on our main domain. right now if I type in my parked domains in Google, they appear in search. The site is all hand coded and not using a CMS.
