Www vs. non-www differences in crawl errors in Webmaster tools...
-
Hey All,
I have been working on an eCommerce site for a while that to no avail, continues to make me want to hang myself. To make things worth the developers just do not understand SEO and it seems every change they make just messes up work we've already done. Job security I guess.
Anywho,most recently we realized they had some major sitemap issues as almost 3000 pages were submitted by only 20 or so were indexed. Well, they updated the sitemap and although all the pages are properly indexing, I now have 5000+ "not found" crawl errors in the non-www version of WMT and almost none in the www version of the WMT account.
Anyone have insight as to why this would be?

In my experience, 301 redirects work better than canonical tags for redirecting non-www to www. Even with the redirects in place, though, you should still use canonicals because it helps prevent duplicate content in cases of query parameters getting indexed.
Here is the htaccess code if you need it:
#Options +FollowSymlinks
Options +SymLinksIfOwnerMatch
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]This will automatically redirect all non-www URLs to www.
-
Not entirely sure if it is set up that way in HTaccess. I do have it set up that way in WMT though (preferred domain.)
Also isn't this what rel=canonical is for? If all my www pages redirected to my non www pages through HT access then what would I use that tag for?
-
Is the non-www version redirecting to www? If not, you should configure your htaccess file so that it redirects. Then you can see if the not found errors persist.

I've submitted a disavow file in my www version account, should I submit one in my non-www version account as well?
My non-www version account is my preferred domain. Should I submit in both account? Or one account will take care of the disavow?

Some Tools Not Recognizing Meta Tags
I am analyzing a site which has several thousands of pages, checking the headers, meta tags, and other on page factors. I noticed that the spider tool on SEO Book (http://tools.seobook.com/general/spider-test) does not seem to recognize the meta tags for various pages. However, using other tools including Moz, it seems the meta tags are being recognized. I wouldn't be as concerned with why a tool is not picking up the tags. But, the site suffered a large traffic loss and we're still trying to figure out what remaining issues need to be addressed. Also, many of those pages once ranked in Google and now cannot be found unless you do a site:// search. Is it possible that there is something blocking where various tools or crawlers can easily read them, but other tools cannot. This would seem very strange to me, but the above is what I've witnessed recently. Your suggestions and feedback are appreciated, especially as this site continues to battle Panda.

How can a Page indexed without crawled?
Hey moz fans,
Intermediate & Advanced SEO | | atakala
In the google getting started guide it says **"
Note: **Pages may be indexed despite never having been crawled: the two processes are independent of each other. If enough information is available about a page, and the page is deemed relevant to users, search engine algorithms may decide to include it in the search results despite never having had access to the content directly. That said, there are simple mechanisms such as robots meta tags to make sure that pages are not indexed.
" How can it happen, I dont really get the point.

Reindexing a site with www.
We have a site that has a mirror - i.e. www.domain.com and domain.com - there is not redirect both url's work and show pages so basically a site with 2 sets of URLs for each page. We have changed it so the domain.com and all assorted pages 301 redirect to the right URL with www. i.e. domain.com/about 301's to www.domain.com/about In the search engines the domain.com is the site indexed and the only www. page indexed is the homepage. I checked in the robots.txt file and nothing blocking the search engines from indexing both the www. and non www. versions of the site which makes me wonder why did only one version get indexed and how did the clients avoid a duplicate content issue? Secondly is it best to get the search engines to unidex domain.com and resubmit www.domain.com for the full site? We are definately staying with the www.domain.com NOT domain.com so need to find the best way to get the site indexed with www. and remove the non www. Hope that makes sense and look forward to everyone's input.

When migrating website platforms but keeping the domain name how best do we add the new site to google webmaster tools? Best redirect practices?
We are moving from BigCommerce to Shopify but maintaining our domain name and need to make sure that all links redirect to their corresponding links. We understand the nature of 301s and are fine with that, but when it comes to adding the site to google webmaster tools, not losing link juice and the change of address tool we are kind of lost. Any advice would be most welcome. Thank you so much in advance!
