I would say it's not really for SEO, but rather for UX, which at the end does affect seo. Meaning that it doesn't mean that your rankings will increase dramatically if you do lazy load.

Hi there.

I don't think there is an actual tool which will tell you that, but you can see it yourself while scrolling on a page - you'll see images loading as you scroll. Also you can use browser's developer console, specifically network tab. You should see images not being loaded until you scroll to them.

Hope this makes sense

_So using /pt-br/ is fine, what really matter is letting Google know the language/location through search console and other measures what language/location the page are targeting. _

Correct, also, do look into meta tag called "hreflang":

I'm not following what you mean in the last sentence: Unless you use some type of CMS, then you can just use RewriteRule or something to only display needed URL.

Most CMS systems have some type of functionality or plugins, which would let you create content in different languages within the same admin, so you wouldn't have to physically create all subfolders etc. So, whenever CMS does that, it would give you URL, but you might use htaccess rewriterule without redirect to make URL look like you want. Just google "rewrite rule without redirect" and you'll see what i'm talking about.

Hope this clarifies a bit

Hi there.

The link you have provided is not a guide for subfolders structuring, it's simply a list of allowed/known language codes for internalization.

To answer your question - it wouldn't matter. It is more for your own ease of use and user friendliness. For example, since you'd have to have different content, you'd have to keep different versions of the website in different folders for ease of finding stuff. This is where different folders structures would come in handy. Unless you use some type of CMS, then you can just use RewriteRule or something to only display needed URL.

Hope this makes sense

Hi there.

Basically, canonical link tells search engines to move all the ranking weight to a page, linked by canonical link. Therefore if google thinks that page A should be ranked for a given keyphrase, but this page A has a canonical link to another page B, page B will be considered as a ranking nominee and page A will be discarded. Which means that all meta data and other things WILL be taken from page B.

Hope this helps.

Crawl resources could be managed through priority use in sitemaps.

After reading all the comments below, it somewhat all goes back to what I was trying to say - tags can help with SEO, but typically don't. Keeping them SEO unfriendly whatsoever might be not the best idea. Noindexing them might help with crawling resources and duplicate content, but not always.

Hi there.

Well, one thing is for sure - do not block tags in robots.txt. That won't help anyhow for sure.

As for organic rankings - at the last company I worked for, I've seen some instances when tag page was ranking for a longer tail keyphrase. So, I would keep tags somewhat SEO friendly. But, as you said, main reason for tags nowadays is UX. Therefore I approach it this way - UX/navigational help first, but, if possible, also make tag SEO friendly. Also 10 tags is too many to my opinion. I believe that recommendations are 2-3 tags, maybe 4, but over that is a murder.

Hope this helps

Hi there.

Well, there are several things you can do to avoid cannibalization:

1. When creating pages for individual webinars - do not post/duplicate content from product pages, just write a description what webinar is about + typical info about webinar - times, speaker info etc.
2. If you do post duplicate content from product pages - use either meta robots or robots.txt to prevent indexing those pages.
3. Add canonical links from these webinar pages to product pages to "redirect" all the juice and rankings.

I think these are the ways to do it, #1 is the way I'd approach it.

Hope this helps.
