Welcome to the Q&A Forum

Is there a percentage (approximate or exact) of duplicate content you should have before you use a canonical tag? Similarly how does Google handle canonical tags if the pages aren’t 100% duplicate? I've added some background and an example below; Nike Trainer model 1 – has an overview page that also links to a sub-page about cushioning, one about Gore-Tex and one about breathability. Nike Trainer model 2,3,4,5 – have an overview page that also links to sub-pages page about cushioning , Gore-Tex and breathability. In each of the sub-pages the URL is a child of the parent so a distinct page from each other e.g. /nike-trainer/model-1/gore-tex /nike-trainer/model-2/gore-tex. There is some differences in material composition, some different images and of course the product name is referred multiple times. This makes the page in the region of 80% unique.

Hello, We have a site that is built using an AJAX application. We include the meta fragment tag  in order to get a rendered page from PhantomJS. The URL that is rendered to google from PhantomJS then is www.oursite.com/?escaped_fragment= In the SERP google of course doesnt include the hashtag in the URL. So my question, with this setup, do i still need a canonical tag and if i do, would the canonical tag be the escaped fragment URL or the regular URL? Much Appreciated!

I'm looking at a bunch of long tail low traffic keywords that aren't difficult to rank for. As I was idly doing a boring task my mind wandered and I thought.... Why don't I ask lots of questions about these keywords on sites such as Moz, Quora, Reddit etc where the high DA will get them to rank for the search term?  The results on a SEO site or Q&A site won't be relevant and so I'd starve my competitors of some of their leads. Of course I'm not sure the effort would be worth it but would it work? (and no, none of my long tail keywords are included in this post)

I am wondering how you would choose which page to use as a canonical ? All our articles sit in an article section and they are called in the url when linked from a particular category. Since some articles are in many categories, we may have several links for the same page. My first idea was to put the one in the article category as the canonical, but I wonder if Google will lose the context of the page for it's ranking because it will not be in the proper category. For exemple, this page in the article section : http://www.bdc.ca/en/advice_centre/articles/Pages/exporting_entering.aspx Same page in the Expand Your Sales > Going Global section : http://www.bdc.ca/EN/advice_centre/expand_your_sales/going_global_or_international_markets/Pages/RelatedArticles.aspx?PATH=/EN/advice_centre/articles/Pages/exporting_entering.aspx The second one has much more context related to it, like the breadcrumb is showing the path and the left menu is open at the right place. For  this example, I would choose te second one, but some articles may be found in 2 or 3 categories. If you could share your lights on this it would be very appreciated ! Thanks

keyword ranking by offpage techniques please provide appropriate answer.

For the past few months I've been working on a new site launch, but have been left with a couple of annoyances from my predecessor.. I've got a couple of questions about best practise (and if it's worth changing now). For reference, a good example page is http://polestars.net/hen-party/life-drawing-hen-party/ H-tags The (external) web designer has insisted that wrapping the logo in an H1 tag (with the same branded H1 text on every page), and using an H2 for the actual title of the page is fine. I really don't believe him, but at the same time, feel like maybe google is smart enough to discern the theme of a page in this structure. Is it worth having this changed so that the actual title is the first H1? Page naming convention Another annoyance that I've been left with is the fact that every product page is named the same "burlesque hen party", "life drawing hen party", "whatever hen party"... It looks a little weird, but my real concern is that as we now have 60 "hen party" links in the navigation menu of a bunch of our pages, this may be seen as keyword stuffing - is this a real concern, or am I overthinking it?

Hello. As I am a SEO Beginner I wonder if the elements of the page will make a better or worse ranking. I ask this because my boss asked to change the order of the elements. He wants to put first the section of Supplies and Accesories, and then additional information. http://www.theprinterdepo.com/hp-9500mfp-refurbished-printer Does it affect my seo for worse or for better?

Just finished reviewing the first crawl of my first SEOmoz campaign for a site that I am working on.  The site I"m working on uses Wordpress as a CMS, and most if not all of the warnings and notices have to do with author, category, and tag pages. Should I block these from being indexed? Why or why not?
