Welcome to the Q&A Forum

What if you have this exact same problem, but the scale is quite large?

For example, when you click on any thumbnail image on this page... http://marketplace.myclassicgarage.com/cars/all/Chevrolet-Corvette-Sting-Ray/52048

it pulls up a new url with duplicate text, title tag, and meta description.  The only thing that changes is the image.

This is just one car.  This issue is generating thousands of duplicate content errors on my crawl report.

I am currently in an internal debate over this issue.  The developer is saying that if we use a canonical then none of these high res images will get indexed for image searches.  I'm saying that this creates a tremendous amount of links on each product page that taxes spiders with nothing but duplicate content and prevents them from perhaps crawling as deeply as they otherwise would.

Thanks Lynn.  I've asked our Dev how painful/painless #1 is as this is a completely bespoke site running Ruby on Rails so no CMS.  Hopefully won't hurt too much.  Thanks again!

Crawl Diagnostics is returning duplicate content/title tags for every product image on listing pages of my classified site because each image is on a separate url.

So this page, for example,

http://marketplace.myclassicgarage.com/cars/all/Chevrolet-Bel-Air/24481/

has, among other things, the same title tag as all this page,

http://marketplace.myclassicgarage.com/cars/all/Chevrolet-Bel-Air/24481/media/151968

which is one of many different images that are all child pages in the folder /media

In this particular case there are over 140 pages with the same title tag because there are over 140 images for this particular car. That is just one listing and there are over 1,000 listings (vehicles) and that number will grow.

Is this really a problem?  With limited resources, what real positive effect will making all these images have unique title tags really have from a SERP perspective?  Keep in mind this being user generated content, there is no way to descriptively update the title tags to something like <title>Bel Air Passenger Side Profile</title>.  That is not feasible.
