Welcome to the Q&A Forum

the reality is slightly different to what i've said, basically the system causes the creation of cat-a/abc not being in cat-b in most cases but rather /featured/abc and /detail/abc or something like that ... we cant restructure the system as it runs on magento and basically that is how it does it. I have deindexed a few bits but i dont think the way it is set up is of great concern to be honest. the concerning bit is more that if moz cant detect that this isnt technically a dupe is it the same for other systems and therefore are others and myself hitting false negative responses for some reason?

if so how do we enable this - we've an average size site with a few hundred products but they appear in multiple categories, canonical url points to it's primary category (but a new page exists for each section... so for /cat-a/abc there will be another page cat-b/abc and again but the canonical points to cat-a always for that product) basically I see this kind of duplication error / notice as a false positive... help me

cache is in the little drop down to the right of the url in searches (usually).

Theres no way to force google to go and reindex the page in full, if its been 6 months and they are still definitely the cause of problems disavow them - whilst not the ideal solution at this point in time it can work. but i advise only doing it if it definitely that site or set of sites causing you issues. you may find google is ignoring those links now but the index just hasnt been updated. Also there is no telling how out of date sections of GWT are.

not that i know of, would be a cool feature though. So pop over to feature request section and let Moz know

There are two solutions, one which is canoncialisation pointing to the correct location, the other (which i prefer for this kind of thing) is to implement 301 redirects from the shorter url.

I think that is ideal because you are saying it's easier to tell people to go to that location, thats fine and great, but we want search to hit the real page - so therefore the second / landing page doesn't need to exist ... just redirect it and avoid confusion.

hope that makes sense

assuming you are talking about a custom url here, you need 200 moz points for the nofollow to be removed from your first cusom link - however i think you are saying its not even showing up... try putting in say google.com and see what happens. it is possible that something has gone amis in the melay of changing interfaces - send moz a tweet and ask for help if you are still stuck @moz

do the links still show in OSE and majestic?

GWT can take 6 months to show a drop of links in my experience, and sometimes longer - it basically will only show it once its revisited the site to makesure the page or link doesn't exist. This means if you are one of say a million links on the page it will take a long time to get reindexed because its huge and likely to be low value - but that link wont disappear until its been reindexed or disavow has been accepted for that page.

Have you spotted any dropping links at all?

As tom suggests, it won't be easy. I've a number of clients with this kind of multi-category set up (one is 5 layers deep!) and its really hard to get juice down to those levels consistently.

For example if you've a product 2 layers deep it seems to be twice as easy for it to gain traction as if it were 4 layers down. This isn't to say it can't be done, it can, but put simply it means you have to really push links at it externally and in social.

Also it sounds like you would benefit from splitting your sitemap by category to that you can focus some attention within sitemaps to these pages rather than have it be one of ten thousand entries.

Basically a 301 redirect is the best option, if you are literally moving a whole domain and the urls will stay the same (save for the domain name) you can use the below

 <ifmodule mod_rewrite.c="">RewriteEngine On
  RewriteCond %{HTTP_HOST} ^olddomain.com$ [OR]
  RewriteCond %{HTTP_HOST} ^www.olddomain.com$
  RewriteRule (.*)$ http://www.newdomain.com/$1 [R=301,L]</ifmodule> 

Thats assuming you are running apache.

most obvious thing is that they tend to link to one another heavily. use open site explorer to check the major links going through and see if one domain points to the others you are thinking about and then check the others.

also check their code and see if they are doing anything funny, like cloaking information - another common blog entwork trick

if they are the same content, targetting the same area/country simple 301 one of the domains to the other. don't try to have two sites with the same content in that case.

if they have different content or targets (aka you are tweaking content for other target areas) then seperate is fine, but i suspect its my former suggestion

fyi http://www.seroundtable.com/google-webmaster-tools-reports-stalled-16756.html

unless you get a warning from google don't be too hasty about trying to remove them. they may hold little value but they probably aren't doing any harm.

nope that won't harm you, try to ensure it links back to you but no it wont do you any harm - it may even help in some cases

I sniffy some billy bull in this article, not least because of the website itself clearly being anti-google... maybe they should have read the latest ruling from the EU regarding favourance of it's own services anot happening before it posts this stuff...

pinch of salt - and all that

interesting to note on it's about page it uses microsofts logo but the blog doesn't mention bing ....

something to check would be in WMT if you go to the advanced section of the index status chart you should see currently in the index and ever indexed, it sounds like you are just seeing the ever indexed number which could be huge for almost any website.

how are you getting on, did this get resolved?

definately sounds like you were penalised - or maybe you blocked google somehow

check for penalisation using http://fruition.net/

just because it may or maynot help with search rankigns doesn't mean those links and comments won't drive traffic. if you add a valuable comment to the blog then people are likely to click through from that site to your own, its not just about rankings

nope though you may get a drop in traffic if there isnt as much search volume in the new local area
