Having a massive amount of duplicate crawl errors
-
Im having over 400 crawl errors over duplicate content looking like this: http://www.mydomain.com/index.php?task=login&prevpage=http%3A%2F%2Fwww.mydomain.com%2Ftag%2Fmahjon http://www.mydomain.com/index.php?task=login&prevpage=http%3A%2F%2Fwww.mydomain.com%2Findex.php%3F etc.. etc... So there seems to be something with my login script that is not working, Anyone knows how to fix this? Thanks

There isn't necessarily anything wrong with your login, it looks like it's carrying a referring parameter in the URL so that it knows where to send you next. Not the most sophisticated way to do it, but very common.
Since it returns a 404 the easiest solution would be to make your login link/button "nofollow". You could add this to the html or javascript fairly easily.
Or you could place a directive in your robots.txt file disallowing these urls, Something like:
User-agent: *
Disallow: *loginshould do the trick. (but test this)
If this is a javascript code causing this, you might try wrapping the script in CDATA tags. This might also do the trick.
Hope this helps. Best of luck with your SEO!

HREFLANG No Return Tag Error
Keep getting WMT no return tag error. Also got an email today on this issue. Here are a couple pages showing up in the error report: Originating URL: /hawaii/kauai-real-estate/ Alternate URL: /jp/hawaii/kauai-real-estate/ Here are the hreflang tags for each page: /hawaii/kauai-real-estate/ /jp/hawaii/kauai-real-estate/ The only thing I can see is the hreflang= is at the end of the snippet but doesn't seem like that would matter. Any thoughts would be greatly appreciated. Thank you.

Duplicate content in Magento
Hi all We got some serious issues with duplicate content on a Magento site that we are marketing. For example: http://www.citcop.se/varmepumpar-luft-luft/panasonic/panasonic-nordic-ce9nke-5-0kw http://www.citcop.se/panasonic/panasonic-nordic-ce9nke-5-0kw http://www.citcop.se/panasonic-nordic-ce9nke-5-0kw All of the above seem to work just fine as it is now but since they are excatly the same product they should ofcourse do a 301 redirect to the main page. Any ideas on how to sort this out in Magnto without having to resort to manual work in .htaccess? Have a great day Fredrik

How critical is Duplicate content warnings?
Hi, So I have created my first campaign here and I have to say the tools, user interface and the on-page optimization, everything is useful and I am happy with SEOMOZ. However, the crawl report returned thousands of errors and most of them are duplicate content warnings. As we use Drupal as our CMS, the duplicate content is caused by Drupal's pagination problems. Let's say there is a page called "/top5list" , the crawler decided /top5list?page=1" to be duplicate of "/top5list". There is no real solution for pagination problems in Drupal (as far as I know). I don't have any warnings in Google's webmaster tools regarding this and my sitemap I submitted to Google doesn't include those problematic deep pages. (that are detected as duplicate content by SEOMOZ crawler) So my question is, should I be worried about the thousands of error messages in crawler diagnostics? any ideas appreciated

Crawl Errors In Webmaster Tools
Hi Guys, Searched the web in an answer to the importance of crawl errors in Webmaster tools but keep coming up with different answers. I have been working on a clients site for the last two months and (just completed one months of link bulding), however seems I have inherited issues I wasn't aware of from the previous guy that did the site. The site is currently at page 6 for the keyphrase 'boiler spares' with a keyword rich domain and a good onpage plan. Over the last couple of weeks he has been as high as page 4, only to be pushed back to page 8 and now settled at page 6. The only issue I can seem to find with the site in webmaster tools is crawl errors here are the stats:- In sitemaps : 123 Not Found : 2,079 Restricted by robots.txt 1 Unreachable: 2 I have read that ecommerce sites can often give off false negatives in terms of crawl errors from Google, however, these not found crawl errors are being linked from pages within the site. How have others solved the issue of crawl errors on ecommerce sites? could this be the reason for the bouncing round in the rankings or is it just a competitive niche and I need to be patient? Kind Regards Neil
