Welcome to the Q&A Forum

I'm also in the camp of do it if it's so easy. Sitemaps are far superior to meta keywords because they're an actual technical specification of a quantifiable thing (image, page, etc.) versus a subjective listing like meta keywords.

Haivng easily and readily indexed images can also help with your backlink profile. XKCD has a great example of allowing for such promotion here: https://xkcd.com/license.html  Obviously his content is more likely to be shared, but even in your case if it's a little help it's still help and is unlikely to hurt. Cheers!

I agree with Andy. Using the brand name is especially applicable if they have established themselves as a brand, and many of the search terms sending visits to the site are also brand tagged.

Yes. Google wants to rank the destination content, not the redirect URL. You could create a static site that links to your individual products and beings to rank, but trying to get a redirect URL to rank will in all likelihood be wasted effort.  Cheers!

I see. But you'll be redirecting to your Amazon page regardless with your current setup as described, so the opportunity for leakage is present at that stage as well.

Again, creating a site and populating it with products that you control is a much better method to both ranking and presenting the products you want to display to visitors.  Cheers!

Hi James! This type of URL rewriting is a best practice when it comes to presenting visitors with easy to read page descriptions so whatever capacity you can apply it would be great. Here's Moz's guide to URLs which goes over your question as well as further details into URL structures: https://moz.com/learn/seo/url

Also note from that page:

In addition to the issues of brevity and clarity, it's also important to keep URLs limited to as few dynamic parameters as possible. A dynamic parameter is a part of the URL that provides data to a database so the proper records can be retrieved, i.e. n=3031001, v=glance, categoryid=145, etc.

Note that in both the Amazon and Canon URLs, the dynamic parameters number three or more. In an ideal site, there should never be more than two. Search engineer representatives have confirmed on numerous occasions that URLs with more than two dynamic parameters may not be spidered unless they are perceived as significantly important (i.e., have many, many other links pointing to them).

Cheers!

Right. It's definitely looking like a Moz side issue since the code and other spiders are saying the links are internal. So I'd put this issue in the 'bug' file and ignore their warning for the time being. They're in Q&A often so you'll get an official word. Again, just a few possible causes tho:

1. System settings could be too specific
2. https could be seen as external to a default of http
3. There could be an issue in processing 'ca' TLDs.

Cheers!

Ah! By 'bug' file I just meant a mental note to yourself so that this issue doesn't hold up other work. Looks like you're doing everything right on your end.

It's a best practice to make sure your whatever software your site is using is patched and up to the latest addition. A high risk warning from that page, "Patch SUPEE-6285 fixes a leak where hackers can take over customer's sessions and download lists of your shop's order details through the RSS feature. Released July 7th, 2015." Would certainly be worth fixing.

From an search perspective, Google has stated that security is a ranking signal: https://webmasters.googleblog.com/2014/08/https-as-ranking-signal.html

Security is a top priority for Google. We invest a lot in making sure that our services use industry-leading security, like strong HTTPS encryption by default. That means that people using Search, Gmail and Google Drive, for example, automatically have a secure connection to Google.

Beyond our own stuff, we’re also working to make the Internet safer more broadly. A big part of that is making sure that websites people access from Google are secure. For instance, we have created resources to help webmasters prevent and fix security breaches on their sites.

We want to go even further. At Google I/O a few months ago, we called for “HTTPS everywhere” on the web.

So making sure your site is secure can have multiple benefits.

You can submit sitemaps as often as you like to Google Search Console. Many large scale sites would even be doing so multiple times a day as they publish new articles, add or remove new products, and so on. For example, News Sites have a high touch need for fast crawling (hence AMP and specialized sitemap methodologies) Here's Google's help article on this: https://support.google.com/news/publisher/answer/40392
