If your idea is to slap on your signature with anchor text heavy links on every forum possible, then no they are not a very good thing to be doing post-2012.

There's a place for them though.  If you're participating on a forum that's relevant to your website then I don't see why you can't place a link or two to your website in the signature.  But I would avoid trying to put manipulative anchor text in there.  Just use the plain URL or a branded term like your business or domain name.

Also, google recently updated their webmaster guidelines with a forum signature example of what you should not be doing:

Forum comments with optimized links in the post or signature, for example:
_Thanks, that’s great info!

This is not something you want to leave up to automation.  You need human input to decide whether a link is bad.  Disavowing innocent links will do more harm than good.

So you have to go through your link profile and focus on the domains that link to you the most, then move onto the ones that link to you with non-branded anchor text.

You don't have to worry about the emanuel update just yet.  It's just one notice.

If you filled the counter form, then no, you don't have to do anything else.  There's no need to file a reconsideration request.

Yep, looks like a big problem.

The good thing though is Google has gotten better at picking up structure problems like this ...those extra pages haven't impacted moz adversely.   If you do a title search, they don't show the cdn version.

But still, it's a simple fix.  They probably have got loads of WMT alerts about Duplicate Titles under HTML improvements.

I'd like to know this as well.

It doesn't matter for the main tags - title and description.

However this guy feels the position of the Content Type meta tag does matter, so you might want to consider that.

The rewrite done by WP is a 301.

So, what CMS are you using ?

I was in the same situation with one site.  Luckily I was using Wordpress/Custom Posts. A change to a slug automatically creates a 301 redirect from the old url to the new url.  There's even plugins that extend to allow the creation of the redirect even when changing the title.  The 301 redirects don't actually go into htaccess, but they are handled by Wordpress and stored in the database.  Another reason why if wordpress were a woman, I'd want to have babies with her.

Do some searching and see if there's a similar extension/plugin or something you can do to have that functionality within your CMS.  If its custom, get your programmer to code it.

Customize and tailor each email as much as possible.  Really look at the target site, follow them on twitter, learn about them, etc

For example, I recently started following a target.  I was going to do a broken link email, but soon enough, they were ranting in a blog post about their brand usernames being taken by squatters and inactive accounts on twitter/facebook.  I used that to reach out to them and suggest what to do to claim their usernames since I actually had the same problem.  I didn't even mention or request links, but they are now linking to our homepage and referencing other pages on my site.  All I did was sign my emails with my domain name, so they know who i am, where i'm from.

Essentially I made a friend by offering value, and asking for nothing in exchange.  That target would have been tough to get a link from otherwise.

In case that hadn't worked out, I WOULD have eventually asked directly for the link after having made a great first impression.

Try using 'broken' link building.

There's several guides and posts here on Seomoz.  Just search.

Basically, you scan through the list of links, and you'll probably find a few broken or 404 pages.  Point those out and also recommend the addition of new resources, including your own.  It works extremely well, and you don't come across as the typical emailer that the webmaster probably encounters everyday.

Round off that strategy with a regular guest posts, link bait and other content marketing ...and you're solid.

Some blackhats/greyhats make it a point to block Mozbot, Majestic and other crawlers from their private networks.   That prevents links from appearing in competitive reports.

So try using Bing's Link Explorer given that they usually allow Bingbot and Googlebot to crawl.
