Welcome to the Q&A Forum

The biz in question sounds like they are shooting themselves in the foot and I'd have to agree that I would not want to work with them.

If the education of the client has been done correctly the decision to create content should be a no brainer as long as that content is intelligently thought out by the consultant.

Can you get away with the image if you add an audio link for the ISI?  Another option might be an iframe.

They are no follow but valuable.  That is all social proof and trust in my eyes.  If you are building just dofollow links you're setting yourself up for trouble so I'd recommend checking the diversity of your link profile.

Hold tight and give yourself at least a week before evaluating the result of your change.

I wouldn't redirect those myself.  I'd just archive them, tack on a sold out notice, tweak the copy and offer a link to the new url.

The project this reminds me of took six months to complete and the 301's alone were a full time job.

Get it right the first time... you do not want to restructure like this on a large dynamic site.

I must say the project worked out but I got all my grey hair the day we threw the switch...

When I say its costly to rewrite 200,000+ URLS I mean it.  Correcting mistakes here can cost big dollars.

In this case it wascostly to the tune of $60,000+ in costs and loss, however the bottle of bubbly at the end of the six month project was tasty.

Point being is to do it right the first time.

As I said before your best bet is documentation.  Large dynamic sites generate large dynamic problems very quickly if not watched closely.

This is how I did it with a local optometrist:

The optometrist has five employees plus himself.  This makes six people.  I instructed the optometrist to have each employee pick a frame they love each day they work.

The employee picks a frame, writes a bit about why the frame is so cool, who would look good in it etc

They take a picture and walah.  Easy blog post.

Through in some other helpful "How To Prep Little Johnny For His Eye Exam" type stuff and you've got useful material.

This allows a small Optic Boutique to create unique web content on a daily basis which, in turn, gives me a way to actual gather social mentions easier than if I had tried to do it with his static brochure site.

As you can tell from the response above indexation is not what you should be worried about.

Dynamic content is not fool proof.  The mistakes are costly and you never want to be involved rewriting 200,000+ pages of dynamic rats nest.

Sorting abilities can cause dynamic urls and duplicate content.

Structure changes or practice changes can cause crawl errors.  I looked at a report for a client early today that had 3000+ errors today compared to 20 last week.  This was all due to a request made by the owner to the developer.

When enough attention is not paid to this stuff it causes real issues.

The best advice I can offer is to make sure you have a best practices document that must be followed by all developers.

Are you looking for Architects, New York?  Our new guide for 2012 has just been released.

There are usually ways to work this stuff into content but as Nakul said, variance is key.

Don't believe everything you read.  Vary your link profile, promote with quality content and stay consistent.

I still have lens' on top of 200 million plus result terms that have been sitting there for years with only other web 2.0 sites linking in.

What is working for me is daily content creation and at least 2 tiers of promotion.

The top level being higher level social sites (think pintrest) being promoted by second tier links such as bookmarking and the profile based social media sites.

This really is a content game in my eyes and my method usually takes a minimum of five pieces (video,article etc).  These are placed strategically along the top tier and promoted on the second tier and yes I am still using squidoo in my procedures.
