TLDR: If you write original content and want to use SEO, Wordproof is one way to get ready for the future. It is still a bet (because search engines are yet to recognize timestamps), yet it is a kind of safe bet because it makes all the sense in the world.

How it works:
Everytime you write content (blog post, page, etc) with Wordproof you can "take a picture in time" of it. Like when in the movies the bad guy takes a picture of the person they have kidnapped with the cover of the newspaper to show that he is still alive.

In this way, you could theoretically dispute that you are the original creator of such content, because you published it first. Now, I am not a lawyer so I don't know how real Wordproof would be as evidence in court, meaning I don't know if the court will lean on the side of the timestamp (what if I just start copying content from great sites and timestamp it before them, would that make it mine?). Also, because copyright infringement could take place in another country around the world, well, good luck with that.

What is certainly very interesting is the possibility to enhance your SEO by timestamping content. This is the gold we content creators can get from Wordproof (if not fully now, soon). And the potential here is so great that they now have Yoast SEO as investors and supporters of Wordproof (ironically I don't use Yoast, I'm Rank Math fan).

Here is what I loved:
- Blockchain technology to store your certificate.
- Once installed, it is a breeze to use in your website and to timestamp old posts and pages (we are on Wordpress).
- Overall, it is a brilliant and simple idea that has tons of potential in it.
- The potential of search engines sometime in the future recognizing timestamps and seeing my SEO scores improve.

Here is what I would change:
- Missing documentation. I struggle from minute one, where they asked me what blockchain technology to use. There are 3 options: EOS, Ethereum, and Telos. I had no idea what to chose or why, but I read somewhere that you have to choose wisely because once you chose it for your website, there is no way to change it. What pressure! They have a "Recommended!" tag on EOS (I have no idea why). And they have a message that Ethereum is "only for paying users" (I have no idea if we LTDs are paying users of Wordproof, or if the meant that somewhere else you get to pay for Ethereum, or maybe if you don't have the free version of Wordproof then you are considered paying user, etc).
- Non-rolling credits. Once the month is over, so are your timestamping credits. Use them or loose them.
- The setup did not honor my post-type selections. Had to redo it.
- I have no idea what happens after we reach the 25 monthly limit.
