Is it possible to "undo" canonical tags as unique content is created?
-
We will soon be launching an education site that teaches people how to drive (not really the topic, but it will do). We plan on being content rich and have plans to expand into several "schools" of driving. Currently, content falls into a number of categories, for example rules of the road, shifting gears, safety, etc. We are going to group content into general categories that apply broadly, and then into "schools" where the content is meant to be consumed in a specific order.
So, for example, some URLs in general categories may be:
Then, schools will be available for specific types of vehicles. For example,
We will provide lessons at the school level, and in the general categories. This is where it gets tricky. If people are looking for general content, then we want them to find pages in the general categories (for example, drivingschool.com/rules-of-the-road/traffic-signs). However, we have very similar content within each of the schools (for example, drivingschool.com/motorbikes/rules-of-the-road/traffic-signs).
As you could imagine, sometimes the content is very unique between the various schools and the general category (such as in shifting), but often it is very similar or even nearly duplicate (as in the example above). The problem is that in the schools we want to say at the end of the lesson, "after this lesson, take the next lesson about speed limits for motorcycles" so there is a very logical click-path through the school. Unfortunately this creates potential duplicate content issues.
The best solution I've come up with is to include a canonical tag (pointing to the general version of the page) whenever there is content that is virtually identical. There will be cases though where we adjust the content "down the road"
to be more unique and more specific for the school. At that time we'd want to remove the canonical tag.
So two questions:
- Does anyone have any better ideas of how to handle this duplicate content?
- If we implement canonical tags now, and in 6 months update content to be more school-specific, will "undoing" the canonical tag (and even adding a self-referential tag) work for SEO?
I really hope someone has some insight into this!
Many thanks (in advance).

I'd agree with Sanket on (1) - while, not a huge fan of creating new URLs for near duplicates (there may be some other ways, like dynamically modifying the content), canonical tags are definitely your best bet here if you need those unique URLs.
I'll add a caveat on (2), though. Sometimes, canonical tags can "stick" a bit longer than you'd like, and Google may not re-index quickly. Adding a self-referential canonical tag does seem to help, anecdotally. What I'd also do is put those URLs back in your XML sitemap once they're unique (I'd leave them out while they're duplicates) - that can spur Google to reindex, and the self-referential tag can tell them to cancel the previous directive. Otherwise, they sometimes act like the old canonical is still in place.

Hi Jessica,
1. Implementation on canonical tag is the best solution in your case
2. Google doesn't index URLs in which you have implemented canonical tag, so I don't think you have to worry about it. After six month when you remove canonical tag I think you will get little boost in ranking as you have updated the page with unique content.
Hope this help you out...

Fast/Easy Way to Implement Canonical tags in Bulk in Magento CMS?
Hello Amazing SEO Community! Quick Q for a client with a TON of duplicate content. (yikes!) My client is currently undertaking a large SEO project around canonical tagging for their thousands of duplicate pages. Currently, one product sits on multiple URLs and they are being indexed as different pages (with the same content). The issue is found across all products and other pages, and across their international sites as well. One core challenge they face now is lack of time/resources from their developer side. The solution we see to the duplicate content is to manually add a canonical tag to each of our tens of thousands of pages. Their content management system is Magento. Has anyone ever tackled canonicalization for a large site that uses Magento? Any more efficient solutions to manual tagging is ideal. Thanks in advance for your input. -Bonnie

Duplicate content, the distrubutors are copying the content of the manufacturer
Hi everybody! While I was checking all points of the Technical Site Audit Checklist 2015 (great checklist!), I found that the distrubutors of my client are copying part of the content to add it in their websites. When I take a content snippet, and put it in quotes and search for it I get four or five sites that have copied the content. They are distributors of my client. The first result is still my client (the manufacturer), but... should I recommend any action to this situation. We don't want to bother the distributors with obstacles. This situation could be a problem or is it a common situation and Google knows perfectly where the content is comming from? Any recommendation? Thank you!

Adding a Canonical Tag to each page referencing itself?
Hey Mozers! I've noticed that on www.Zappos.com they have a Canonical tag on each page referencing it self. I have heard that this is a popular method but I dont see the point in canon tagging a page to its self. Any thoughts?

Why does old "Free" site ranks better than new "Optimized" site?
My client has a "free" site he set-up years ago - www.montclairbariatricsurgery.com (We'll call this the old site) that consistently outranks his current "optimized" (new) website - http://www.njbariatricsurgery.com/ The client doesn't want to get rid of his old site, which is now a competitor, because it ranks so much better. But he's invested so much in the new site with no results. A bit of background: We recently discovered the content on the new site was a direct copy of content on the old site. We had all copy on new site rewritten. This was back in April. The domain of the new site was changed on July 8th from www.Bariatrx.com to what you see now - www.njbariatricsurgery.com. Any insight you can provide would be greatly appreciated!!!

Are all duplicate content issues bad? (Blog article Tags)
If so how bad? We use tags on our blog and this causes duplicate content issues. We don't use wordpress but with such a highly used cms having the same issue it seems quite plausible that Google would be smart enough to deal with duplicate content issues caused by blog article tags and not penalise at all. Here it has been discussed and I'm ready to remove tags from our blog articles or monitor them closely to see how it effects our rankings. Before I do, can you give me some advice around this? Thanks,

Need help with duplicate content. Same content; different locations.
We have 2 sites that will have duplicate content (e.g., one company that sells the same products under two different brand names for legal reasons). The two companies are in different geographical areas, but the client will put the same content on each page because they're the same product. What is the best way to handle this? Thanks a lot.
