Fixing some SEO basics

[rraue]

I did a small SEO check on the website and nothing big showed up, but some things should be pretty feasible to implement, making it easier to crawl without confusion and some changes to the titles. I noticed as well, that all pages have no description, this will lower the CTR in search results because search engines need to come up with one by themselves and that looks mostly random like that:

To Do (most I can do myself, but descriptions and homepage title I can't provide):

• [x] Set self-referencing absolute canonicals, so we do not have duplicate content as the page is reachable vie the github and mozilla subdomain

• [x] Switch title-schema and set "- Mozilla IoT" at the end of the title, not at the beginning, the document name and title is more important, than the general website name

• [ ] The homepage should have a more speaking title as well

• [ ] Ad a meta description for all pages with min 100 and max 160 characters

• [x] fix nav-links to include trailing slash, so no redirect is triggered

Hi @rraue, thanks for the proactive review. I didn't know we had a head of SEO! Is that like a Professor of the Dark Arts? ;)

It would be easier to review these changes if you could put them in a single pull request.

I can work on some descriptions for the page metadata and a more descriptive title for the home page.

Just curious, what is the benefit of adding trailing slashes to all the URLs?

I would rather not make the hyperlink on the main logo an absolute URL because it won't work properly on our staging servers.

Thanks
