Noindex Valuable duplicate content?

[Rich_Coffman]

How could duplicate content be valuable and why question no indexing it?

My new client has a clever african safari route builder that you can use to plan your safari. The result is 100's of pages that have different routes. Each page inevitably has overlapping content / destination descriptions. see link examples.

To the point - I think it is foolish to noindex something like this. But is Google's algo sophisticated enough to not get triggered by something like this?

Thanks Gianluca Fiorelli

Based on your response I will leave the pages indexable and encourage my client to add extra testimonials in the beginning of each page.

Google is surely able to calculate the grade of duplication between different web documents.

But I am also sure the it is also quite able to understand when this substantial duplication is due to poor thin content and when it is "structurally editorial".

In the examples you gave, the pages are substantially similar but also distinct, thanks to the introduction to the tour and the evaluation by the expert.

You could try to differentiate the two pages more adding one or two testimonials by clients. That would be useful also for the users, not just Google.

Generally, even if it's true that we should avoid duplications or substantial duplication, we should also think in term of value given to the users. In fact, we craft different pages, but if they are substantially spinned versions of the same content, the value will be very poor.
