Penalization for Duplicate URLs with %29 or "/"
-
Hi there -
Some of our dynamically generated product URLs somehow are showing up in SEOmoz as two different URLs even though they are the same page- one with a %28 and one with a
e.g.,
http://www.company.com/ProductX-(-etc/
http://www.company.com/ProductX-(-etc/
Also, some of the URLs are duplicated with a "/" at the end of them.
Does Google penalize us for these duplicate URLs? Should we add canonical tags to all of them?
Finally, our development team is claiming that they are not generating these pages, and that they are being generated from facebook/pinterest/etc. which doesn't make a whole lot of sense to me. Is that right?
Thanks!

Canonical tags should drastically help with this. The % is being generated because the URL is being encoded and has a "(" in it. Have your product page each contain their own canonical with the URL you want indexed. Not sure which URL to use? Check your internal links and see how your site is linking to your product pages. Presumably its:
http://www.company.com/ProductX-(-etc/
or
http://www.company.com/ProductX-(-etc
Add this URL as your canonical and the SE's will understand what page is the 'real' page. This will solve both problems from an SEO standpoint. If you want to actually stop the site from doing this, you can remove trailing slashes and encoding using HTACCESS.

In short, your site software should completely control all links generated on your site. If you hand code a site using .NET, Cold Fusion, HTML/CSS/PHP, etc. you are in complete control over your links. If you use a CMS or other software such as WordPress, Magento, etc. then the software creates the URLs for you. In either case a skilled developer should be able to offer you options.
In brief, I recommend using a standard format for your URLs. We like to have all categories end with a trailing slash, and all web pages end without one. For example: www.mysite.com/cars/ or www.mysite.com/cars/2010-ford-mustang.
Whatever choice you make, enforce it throughout your site. You can also use the canonical tag to help control issues where a page may be offered under multiple URLs, but the best choice would be solving the root issue.
**Our development team is claiming that they are not generating these pages, and that they are being generated from facebook/pinterest/etc. which doesn't make a whole lot of sense to me. **
Without looking at your website and an example URL of this issue, it is not possible to offer a definitive answer. I have never encountered this issue.

Are "appliance repair" and "appliance repair los angeles" consider the same keyword?
Hello, I know that you can't optimize two pages for 1 keyword because Google will get confused and will rather prefer my competitor. But I can't get if it will consider "appliance repair" and "appliance repair los angeles" same keywords? The homepage of my website, https://www.ifixappliancesla.com, is optimized for "appliance repair", one of the inner pages is optimized for "appliance repair los angeles". None of them shows on the first page in local SERPs for any of those quires. I am wondering if this is because Google sees it as both pages are optimized for "appliance repair"?

Fixing Duplicate Pages Titles/Content
I have a DNN site, which I created friendly URL's for; however, the creation of the friendly URL's then created duplicate page content and titles. I was able to fix all but two URL's with rel="canonical" links. BUT The two that are giving me the most issues are pointing to my homepage. When I added the rel = "canonical" link the page then becomes not indexable. And for whatever reason, I can't add a 301 redirect to the homepage because it then gives me "can't display webpage" error message. I am new to SEO and to DNN, so any help would be greatly appreciated.

N/A page rank or "grey bar"
I have a web site that is over 10 yrs old, It also has over 30,000 links to it. Last week it received a N/A or "grey bar" page rank. The site also still is listed in the SERPS for my keywords, in fact for a few they have actually improved. The organic traffic is following the same pattern as last year. Webmaster tools doesnt list any critical issues or errors. Is there anything I can do to remedy the situation, or is this just a wait and see? Website is www.netnanny.com.

How valuable is content "hidden" behind a JavaScript dropdown really?
I've come across a method implemented by some SEO agencies to fill up pages with somehow relevant text and hide it behind a javascript dropdown. Does Google fall for such cheap tricks? You can see this method used on these pages for example (just scroll down to the bottom) - it's all in German, but you get the idea I guess: http://www.insider-boersenbrief.de/ http://www.deko-und-kerzenshop.de/ How is you experience with this way of adding content to a site? Do you think it is valuable or will it get penalised?

Confused about rel="canonical"
I'm receiving a duplicate content error in my reports for www.example.com and www.example.com/index.htm. Should I put the rel="canonical" on the index page and point it to www.example.com? And if I have other important pages where rel="canonical" is being suggested do I place the rel="canonical" on that page? For example if www.example/product is an important page would I place on that page?
