Welcome to the Q&A Forum

Hi Dstrunin,

I would still use the rel canonical tag even with or without the filter in place.  So if you have a list of products displayed unfilter at companyname.com/productcategory/page1.htm, I would add a rel canonical  with it pointing at companyname.com/productcategory/page1.htm.  For the filtered results,companyname.com/productcategory/filters/page1.htm , the canoncial tag would still point to companyname.com/productcategory/page1.htm.

It doesn't hurt to have a canonical tag point to the same page it's on.

If you can't do that I would meta noindex those filtered pages and remove the robots.txt stuff.  Robots.txt doesn't tell Google they can't index it it only says they can't crawl it.  So they could still index old stuff they crawled before you did the robots.txt stuff or index the title tags.

Hi DragonSearch,

Edgecast is a basic CDN provider which will help your speed and performance on your website.  We at SEOmoz have our own custom CDN which allows us to load our webpages from one server and load our images and other large documents from another server.  If you look at the code on our site you will see some of our images come from http://cdn.seomoz.org.  This is all to increase the speed of our site and reduce the load on our servers.  In the big picture I would spend lots of money on a service like this since it will only have a minor role on your SEO efforts.

Hi Thomas,

I've done some studies on this and you will be fine using this technique and Google won't give you any problems doing it.  Check out my post on the Honeypot Technique, http://www.seomoz.org/blog/captchas-affect-on-conversion-rates.  The technique works quite well blocking about 98% of SPAM.

Hi Tim,

There is a new version of OSE in the works currently, though I'm not sure if that feature will be in there.  I know that the web app is set to have some for of historial tracking so stay tuned.  You can also submit feature requests here: http://www.seomoz.org/dp/change-log

Hi LameMule,

Those site links are hard to control and really it's an automated process that Google uses to generate the title for those links.  My suggestion is to make sure that all your internal linking is set the way you want it to display in your site link.  My guess is that Google is coming across different versions of anchor text pointing internally to your page and then changing it based on that.

Hi Francesco,

The problem is that .uk.com is not a true TLD, like .uk.com, .com, or .org, it's actually a subdomain of the domain uk.com.  So those 24 million links you are seeing are for the domain uk.com and not your site.  The true TLD for the UK is .co.uk and not .uk.com.  So your website is really just a subdomain of a very big domain.  To get information for your site you will only be able to look at the subdomain information and not the root domain level.

Hi Vijay,

That article was out of date and replaced by a chapter in our Beginners Guide to SEO, there are still copies out there from other peoples websites but we don't have it on our site.  Check out the chapter in the guide here: http://guides.seomoz.org/chapter-7-growing-popularity-and-links

A thing to remember is that OSE doesn't discount any links or websites that may be spammy.  My guess is that Google is discounting those links and pages since Squidoo is known to be very spammy and most likely was effected in the last updated by Google.  My suggestion would be not to follow in the same suite as them and avoid falling into getting links from these type of spammy places.
