404 Errors After Site Migration
-
Hello -
I'm working on a website selling fashion accessories. The site just went through a site migration from Yahoo! to Big Commerce. Now we have a high level of warnings and errors from the crawl. Few are mentioning sites I never seen before on the Yahoo! platform. I also notice that the pages crawled has doubled. How can I fix or did I do something wrong with migration?
I was running the website with minimal errors and now overwhelmed with errors all the error updates. If I can get some assistance on what could be wrong, I would greatly appreciate.
Thanks.

Well, I myself can't tell you why those pages would have errors - I don't know your site to know what is right/wrong or what your folder structure needs to be to ensure the path is correct. Or, as things that have happened to me, for example, in Google Webmaster tools, I'll get notification for 404's to my site pages...even though those pages don't exist. What do I mean? I mean someone linked to my site, but messed up the URL so they (unintentionally) created a bad URL that Google associated with my site. So when you say you have a high amount of errors/warnings, I'd just suggest looking at what tool is providing that information to determine how credible that is.
As for those URLs you shared, are all those legit pages but aren't rendering correctly? Or, are they not real pages at all but somehow the URL was created in the move? (Someone else may be better at chiming in there other than myself.)
I suggest going back and redirecting all the bad pages to a good page, or serve up your 404 page for any bad links you want to fall out.
Even with errors, sites can do better with traffic if the migration means that the site is more crawlable and that along with the migration, if it's easier for search engines to figure out what your site is about and match it to search queries.

Thanks much Andrea, I'm so very new to SEO and all the errors freaking me out!
Yes the migration changed the URL structure. I thought I went through them very carefully to make sure each URL matched (not sure why not all of the URL successfully submitted with matched URLs).
I also upload all the previous redirects via Yahoo onto the new platform.
I updated the new sitemap to the search engines (Google, Yahoo)
For example, the below links showing as errors and can't figure as too why. I updated the sitemap:
http://www.shopchameleon.com/a-black-mesh-bow-belt/index.html
http://www.shopchameleon.com/a-black-mesh-bow-belt/privacypolicy.html
http://www.shopchameleon.com/ballerina-cool-earring/testimonials.html
But also strange that when migrated and w/ all these errors the website is getting double amount of traffic??

Wondering if you can give a bit more background - so did the migration change your URLs/URL structure? If so, what was your link plan to set up redirects from the old URLs to the new ones? Did you update your site map to indicate to the search engines you've migrated? Did you 404 any old content that you weren't moving?
As for your comment "Few are mentioning sites I never seen before on the Yahoo! platform" I'm not sure what you mean - what sites are you referring to? Yours? Sites that were linking to your old site...?

Sitemap error in Webmaster tools - 409 error (conflict)
Hey guys, I'm getting this weird error when I submit my sitemap to Google. It says I'm getting a 409 error in my post-sitemap.xml file (https://cleargear.com/post-sitemap.xml). But when I check it, it looks totally fine. I am using YoastSEO to generate the sitemap.xml file. Has anyone else experienced this? Is this a big deal? If so, Does anyone know how to fix? Thanks EwTswL4

Duplicate content and 404 errors
I apologize in advance, but I am an SEO novice and my understanding of code is very limited. Moz has issued a lot (several hundred) of duplicate content and 404 error flags on the ecommerce site my company takes care of. For the duplicate content, some of the pages it says are duplicates don't even seem similar to me. additionally, a lot of them are static pages we embed images of size charts that we use as popups on item pages. it says these issues are high priority but how bad is this? Is this just an issue because if a page has similar content the engine spider won't know which one to index? also, what is the best way to handle these urls bringing back 404 errors? I should probably have a developer look at these issues but I wanted to ask the extremely knowledgeable Moz community before I do 🙂

Migrating to new subdomain with new site and new content.
Our marketing department has decided that a new site with new content is needed to launch new products and support our existing ones. We cannot use the same subdomain(www = old subdomain and ww1 = new subdomain)as there is a technically clash between the windows server currently used, and the lamp stack required to run the new wordpress based CMS and site. We also have an aging piece of SAAS software on the www domain which is makes moving it to it's own subdomain far too risky. 301's have been floated as a way of managing the transition. I'm not too keen on that idea due to the double effect of new subdomain and content, and the SEO impact it might have. I've suggested uploading the new site to the new subdomain while leaving the old site in place. Then gradually migrating sections over before turning parts of the old site off and using a 301 at that point to finalise the move. The old site would inform user's there is a new version and it would then convert them to the new site(along with a cookie to auto redirect them in future.) while still leaving the old content in place for existing search traffic, bookmarks and visitors via static URLs. Before turning off sections on the old site we would create rel canonicals to redirect to the new pages based on a a mapped set of URLs(this in itself concerns me as the rel canonical is essentially linking to different content). Would be grateful for any advice on whether this strategy is flawed or whether another strategy might be more suitable?

Does my "spam" site affect my other sites on the same IP?
I have a link directory called Liberty Resource Directory. It's the main site on my dedicated IP, all my other sites are Addon domains on top of it. While exploring the new MOZ spam ranking I saw that LRD (Liberty Resource Directory) has a spam score of 9/17 and that Google penalizes 71% of sites with a similar score. Fair enough, thin content, bunch of follow links (there's over 2,000 links by now), no problem. That site isn't for Google, it's for me. Question, does that site (and linking to my own sites on it) negatively affect my other sites on the same IP? If so, by how much? Does a simple noindex fix that potential issues? Bonus: How does one go about going through hundreds of pages with thousands of links, built with raw, plain text HTML to change things to nofollow? =/

404 error - but I can't find any broken links on the referrer pages
Hi, My crawl has diagnosed a client's site with eight 404 errors. In my CSV download of the crawl, I have checked the source code of the 'referrer' pages, but can't find where the link to the 404 error page is. Could there be another reason for getting 404 errors? Thanks for your help. Katharine.

Mass 404 Checker?
Hi all, I'm currently looking after a collection of old newspaper sites that have had various developments during their time. The problem is there are so many 404 pages all over the place and the sites are bleeding link juice everywhere so I'm looking for a tool where I can check a lot of URLs at once. For example from an OSE report I have done a random sampling of the target URLs and some of them 404 (eek!) but there are too many to check manually to know which ones are still live and which ones have 404'd or are redirecting. Is there a tool anyone uses for this or a way one of the SEOMoz tools can do this? Also I've asked a few people personally how to check this and they've suggested Xenu, Xenu won't work as it only checks current site navigation. Thanks in advance!
