Welcome to the Q&A Forum

Having thousands of no-follow site wide links is unlikely to be worth very much if anything. You'd be better off getting a small number of links from domains that are authoratitve and/or relevant to your niche. So think about getting links that have a high contextual relevance too. (The content in which they appear is about the same topic). There's a risk that site-wide links get people into trouble with penguin / unnatural links and anchor text over-optimisation. The exception here is where the links have the potential to bring you relevant direct traffic which have have a high conversion rate depending on the source.

For months, Google has sometimes added SEOmoz to the end of our title tags after we moved to Moz. Sometimes Google will do their own title tags, and have for years.

LOL Paul - I don't know you as well as I hope to in the future, however you have already through the multiple interactions we've had, proven you're trustworthy, friendly and a good person by nature (your actions have spoken). So yes, this is a great example of how to build a valid professional relationship.  Because even if you hadn't made that referral, the interactions themselves beyond that have been high quality and "trustworthy".  So I am already inclined to be of help should the situation arise.

I really like Dana's response - it covers the primary consideration - how much time would it REALLY take to write unique Meta descriptions? If the TRUE answer is "unrealistically too much time", then a template COULD work. The trick though is addressing the issues Dana talks about. If you only use a primary product name as the variable, you run risks. If you have a 2nd database field you have that includes some differentiation between otherwise identical products, that can help.  As long as you understand total length as a consideration.

Not that much people will actually link to you (people are naturally lazy or don't have blogs) so don't worry. I would just put the site's brand in there like "Link to Brand or url" and have it change from time to time. You can have you developer create a simple form where people can enter what they want and it would generate an embed code which will fit their site/blog perfectly. In my experience, people will choose to use social buttons rather than sharing actual links on their blogs (I'm referring to regular people unless you target bloggers) so having the buttons there would give you more benefits rather than not having it on the page.

Mozcast also record a spike in the Google weather between 1st and 3rd November, but there were bigger rises between 23rd and 28th October showing more changes went on during that period. http://mozcast.com/ Peter

Google is very good at devaluing links nowadays so I wouldn't worry too much. If a company wants to conduct negative SEO against your website then they can't be a serious competitor because nobody in their right mind would waste time and money trying to get a competitors' website hit. As Doug said, concentrate on creating some great content around your business/niche and then look at your outreach.
