Rel="canonical" for PFDs?
-
Hello there,
We have a lot of PDFs that seem to end up on other websites. I was wondering if there was a way to make sure that our website gets the credit/authority as the original creator. Besides linking directly from the PDF copy to our pages, is anyone aware of strategy for letting Google know that we are the original publishers?
I know search engines can index HTML versions of PDFs, so is there anyway to get them to index a rel="canonical" tag as well?
Thoughts/Ideas?

I stand corrected on that point.
Thank you Jassy for sharing the link. I was not aware Google made that change.

I'm not sure that statement about rel canonical only working within your own domain - if you have some test data/similar that shows this to be the case, I'd love to hear about it.
Matt Cutts specifically says that cross-domain rel canonical is supported, see: the webmaster video on: iwww.youtube.com/watch?v=zI6L2N4A0hA

Canonical tags are only effective within your domain. They have no value if someone else was to take your work and share it elsewhere.
A few things you can do to establish yourself as the original content creator:
-
publish it first on your site. Wait until you see your content in Google before actively distributing the pdf to others. This would be one indicator that can be used to demonstrate you are the original author.
-
as you shared, ensure there are links back to your site within the PDF. This would be another good indicator to Google that you are the content creator.
-
lock the PDF so changes cannot be made to the content.
-
Earlier today Google announced the new schema.org microdata offers an author tag so you can determine the original author. That system has been tested and is available to use now.

Is "commented out" text still read by the SEs?
A site I reviewed was showing up in Google rankings for key phrases specific to a city, however the page that was showing up had the 'city' key phrases commented out. Does Google still read and utilized commented out text? Or is it more likely that the page in question got indexed before the key phrases were commented out and it's just still appearing for the related search queries?

Should I change these "Overly dynamic URLs" ?
Hello, My client have pages that look like this: www.domain.com/blog/index.aspx?blogmonth=1&blogday=10&blogyear=2012&blogid=256 Question 1: SEOMoz say they are overly dynamic. Is it really in this case as the numbers indicate the year, month and day and do not change? Question 2: Should we change the URLs to proper SEO friendly URLs such as www.domain.com/keywords1-keyword2? The pages are already ranking well and we worry that changing the URL may damage the ranking? Do we risk the page to go down in ranking by creating SEO friendly URLs? (and using a 301 to redirect from the old URL)

Hyphenated Domain Names - "Spammy" or Not?
Some say hyphenated domain names are "spammy". I have also noticed that Moz's On Page Keyword Tool does NOT recognize keywords in a non-hyphenated domain name. So one would assume neither do the bots. I noticed obviously misleading words like car in carnival or spa in space or spatula, etc embedded in domain names and pondered the effect. I took it a step further with non-hyphenated domain names. I experimented by selecting totally random three or four letter blocks - Example: randomfactgenerator.net - rand omf act gene rator Each one of those clips returns copious results AND the On-Page Report Card does not credit the domain name as containing "random facts" as keywords**,** whereas www.business-sales-sarasota.com does get credit for "business sales sarasota" in the URL. This seems an obvious situation - unhyphenated domains can scramble the keywords and confuse the bots, as they search all possible combinations. YES - I know the content should carry it but - I do not believe domain names are irrelevant, as many say. I don't believe that hyphenated domain names are not more efficient than non hyphenated ones - as long as you don't overdo it. I have also seen where a weak site in an easy market will quickly top the list because the hyphenated domain name matches the search term - I have done it (in my pre Seo Moz days) with ft-myers-auto-air.com. I built the site in a couple of days and in a couple weeks it was on page one. Any thoughts on this?

Canonical pagination content
Hello We have a large ecommerce site, as you are aware that ecommerce sites has canonical issues, I have read various sources on how best to practice canonical on ecommerce site but I am not sure yet.. My concert is pagination where I am on category product listing page.. the pagination will have all different product not same however the meta data will be same so should I make let's say page 2 or 3 to main category page or keep them as is to index those pages? Another issue is using filters, where I am on any page and I filter by price or manufacturer basically the page will be same so here It seems issue of duplicate content, so should I canonical to category page only for those result types? So basically If I let google crawl my pagination content and I only canonical those coming with filter search result that would be best practice? and would google webmaster parameter handling case would be helpful in this scenario ? Please feel free to ask in case you have any queries regards

How rel=canonical works with index, noindex ?
Hello all, I had always wondered how the index,noindex affects to the canonical. And also if the canonical post should be included in the sitemap or not. I posted this http://www.comparativadebancos.co... and with a rel=canonical to this that was published at the beginning of the month http://www.comparativadebancos.co... but then I have the first one in google http://www.google.com/search?aq=f... May be this is evident for you but, what is really doing the canonical? If I publish something with the canonical pointing to another page, will it still be indexed by google but with no penalty for duplicate content? Or the usual behaviour should have been to havent indexed the first post but just the second one? Should I also place a noindex in the first post in addition to the canonical? What am I missing here? thanks
