Agreed. URL A is now a higher authority page because of the proper canonical, which in turn means a link from URL A could have more value. But the equity from that link to URL B is not directly passed to your site.

Pageviews specifically...no. Popularity...yes. User experience is far more important though and Google's approach is based on sites giving users great experience and relevant content.

Like Kingof5 said, OSE doesn't do as large a crawl as many other tools out there. They pride themselves on accuracy not volume.

It looks like a large site, probably with many subdomains. OSE likely just has crawled that page or hasn't in a long time. Might want to take a look at the sitemap, see if those pages/subdomain/link to that sitemap subdomain are contained in it.

As long as it is in the section of your page. Crawlers look for tagging information in this section first so it may be missed if it is anywhere else.

If you are concerned about the amount of code in the top head section, you could move all that javascript into a external js file and reference it.

I assume you're using OSE? It looks like rogerbot hasn't crawled the page - which why it doesn't show PA or links.

I can share a couple of free tools I find useful (other than Google Keyword Planner)...

Google Trends is always a good broad tool to look at to see where popularity for those keywords are at. Of course your keywords will need to have enough volume, but you can get pretty good segmentation now in GTrends.

Ubersuggest is a great tool to find a huge list of related variations to your keywords. Very useful for planning out content.

Moz's Keyword Analysis tool I find is very useful for judging the difficulty of the keywords you are researching. You want to target keywords that have enough traffic, but also are not to competitive if you are starting some initial optimization.

SEMRush is another useful and popular tool for keyword research. You can get traffic estimates and competition level estimates for a large index of keywords in localized Google serps. It is free for limited data - paid for full results.

You can also use tools like Fresh Web Explorer, AllTop, Topsy and even Google Alerts to give you ideas of popularity of keywords and different content groups.

TL;DR Moz is great for difficulty and competition research, but there are better tools (and free!) on the market for traffic and popularity measuring - use a combination of both!

Hope this gives you some ideas!

Your header images should not have h1 tags in them as well because then every page is going to have the same h1 tag with the same keyword - making it so that your are optimizing against that keyword on all your other pages.

Google looks at h1 tags as clues to what the page's content is about. If you have multiple h1 tags with different keywords then it is difficult for Google to contextualize the page.

Best practice: one h1 tag with the keyword or theme you are trying to optimize for.
