You should utilize og:locale:alternative and have og:locale set to the country you want to present it to. see details here.

Overall, since its English in both scenarios, I don't think you need to worry about it.

Can we see example of the search console error?

Here is a news site that does it well so maybe study their code? http://qz.com/723397/the-incredible-things-that-had-to-go-just-right-for-juno-to-reach-jupiter/

1 visit, 3 pageviews

From an SEO perspective, each page is considered a part of the same article. So the difference is really you get more page views if you split it up (given that users will choose to go to next page)

1. use 302 (temporary) instead of 301 (permanent) redirects2) you want to be sure that Googlebot isn't redirected to the old site (which would hurt your new site rankings) - Here is how to verify googlebot.

Note: Googlebot crawlers all originate in California

Don't expect the old site to rank (since Google won't follow the redirect) but new site should be fine.

Here is how to do it properly: https://webmasters.googleblog.com/2014/02/infinite-scroll-search-friendly.html

Theoretically, if you paginate it correctly, it shouldn't make a difference (each paginated page would be treated as part of a whole). If you don't, might hurt you for having more thinner pages vs fewer quality pages (it doesn't sound like you will be targeting any additional keywords).

Ran another crawler and didn't see any issues so I think you should be good technically.

I also ran a stress test and there were times when the VU couldn't access the page (although generally this would throw up another error code, could be the reason for the 406).

Currently, Google only looks at the desktop version of the page for it's index so collapsing for mobile would have no effect on rankings.

In general, Google says that hidden/collapsible content is given less weight than visible since its not considered as important for users to see.

screenshot?

We need more info. Site? URL the 404 had an inbound link from?

While going through your site, the crawler encountered a link that it followed which resulted in the server returning a 404 status code (not found).

Here is Google's official recommendations for website testing. According to them, no amount of cloaking is okay. Try using one of the other methods suggested.

Yes, that would do good. Since content is identical for each of these products, there should only be 1 URL with all of the variations of that product in order to consolidate all of the authority. If you want to keep all of the variations in search, look into creating anchor links that point to the same "master" url. e.g. http://www.prams.net/easywalker-mini-buggy-lightweight-union-jack-b can be linked as http://www.prams.net/easywalker-mini#union-jack

That way, the URL is the structure is more SEO friendly but aesthetically the site is identical.

yeah, if you search for a facebook page on majestic, it will return backlinks to that specific page. you're right about that not being the case for OSE.

Majestic provides data for FB pages.

To your point, a backlink from a high authority FB page may be weighted more than one from a new/fake one.

He also mentioned 500 backlinks to the Facebook page, which I will assume aren't crappy. If they are legit, I would try to avoid changing the Facebook URL. Maybe you create a separate FB page and outreach to the webmasters and ask them to update the URL (or better yet, link back to your website instead). Later on, you can merge the two pages.

amazon, zappos, walmart, microsoft store - many ecommerce sites don't use tabs.

A common workaround seems to be to have "tabbed navigation" but instead of toggling visibility, it scrolls down to the corresponding section.

Agreed with one note... its a really bad idea if you are already ranking for the terms you like to. There will definitely be a period of time where you will lose your rankings and although they should return to their previous rankings, Google is fickle.

So if you aren't ranking in the top 50 for several terms, simply changing the URL won't get you to the first page (it may get you into the top 50 though). You would need to update the content and backlinks (internal + external) to see worthwhile movement. Otherwise you just risk losing ranking for the terms you currently do well for.
