How to block "print" pages from indexing

[NakulGoyal]

Yes, it's strongly recommended. It should be fairly simple to populate this tag with the "full" URL of the article based on the article ID. This approach will not only help you get rid of the duplicate content issue, but a canonical tag essentially works like a 301 redirect. So from all search engine perspective you are 301'ing your print pages to the real web urls without redirecting the actual user's who are browsing the print pages if they need to.

I have to agree with Jen - Robots.txt isn't great for getting indexed pages out. It's good for prevention, but tends to be unreliable as a cure. META NOINDEX is probably more reliable.

One trick - DON'T nofollow the print links, at least not yet. You need Google to crawl and read the NOINDEX tags. Once the ?print pages are de-indexed, you could nofollow the links, too.

Yes, but Rel=Canonical does not block a page it only tells google which page to follow out of two pages.The question was how to block, not how to tell google which link to follow. I believe you gave credit to the wrong answer.

This is not fair. lol

But the spiders still run on the page and read the canonical link, however with the robot text the spiders will not.

Although you are correct... there is still more then one way to skin a chicken.

Your welcome : )

You are right Donnie. I've "good answered" you too.

I've gone ahead and updated my robots.txt file. As soon as I am able, I will use no indexon the page, no follow on the links, and rel=canonical.

This is just what I needed, a quick fix until I can make a more permanent solution.

[Dr-Pete]

Rel-canonical, in practice, does essentially de-index the non-canonical version. Technically, it's not a de-indexation method, but it works that way.

Josh, please read my and Dr. Pete's comments below. Don't nofollow the links, but do use the meta noindex,follow on the page.

[Dr-Pete]

Sorry, but I have to jump in - do NOT use all of those signals simultaneously. You'll make a mess, and they'll interfere with each other. You can try Robots.txt or NOINDEX on the page level - my experience suggests NOINDEX is much more effective.

Also, do not nofollow the links yet - you'll block the crawl, and then the page-level cues (like NOINDEX) won't work. You can nofollow later. This is a common mistake and it will keep your fixes from working.

Thanks Jennifer, will do! So much good information.

Donnie, I agree. However, we had the same problem on a website and here's what we did the canonical tag:

Over a period of 3-4 weeks, all those print pages disappeared from the SERP. Now if I take a print URL and do a cache: for that page, it shows me the web version of that page.

So yes, I agree the question was about blocking the pages from getting indexed. There's no real recipe here, it's about getting the right solution. Before canonical tag, robots.txt was the only solution. But now with canonical there (provided one has the time and resources available to implement it vs adding one line of text to robots.txt), you can technically 301 the pages and not have to stop/restrict the spiders from crawling them.

Absolutely no offence to your solution in any way. Both are indeed workable solutions. The best part is that your robots.txt solution takes 30 seconds to implement since you provided the actually disallow code :), so it's better.
