[docs] Showcase, reorder based on SimilarWeb Global Rank

[mbrookes]

• I have followed (at least) the PR section of the contributing guide.

sfrpresse.sfr.fr doesn't have a SimilarWeb Global Rank for some reason, but it does have visits, and averages pages per visit, so I slotted it in based on that. The order is only ever going to be approximate, so good enough for our purposes.

What's the advantage of using the global ranking? Why is the number of visits, not enough? Also, should we take more dimensions into account? Like the quality of the integration, the open source status or the release date of the website?

Why is the number of visits, not enough?

Most sites don't have enough data to display this metric.

Also, should we take more dimensions into account?

Be my guest.

Yeah, it just means these websites have no traffic or it's not significant. This is a data we can leverage. I think that the only the order of magnitude is important here, not the absolute value. I would use a logarithm base 10.

I wonder what the global rank is based on in that case?

I would use a logarithm base 10.

That wouldn’t change the order by itself, so why go to the trouble?
