SEO on the blockchain

1. The list of keywords is converted to ERC-721 tokens. Each search query is assigned a separate token.

2. On the subdomain of the main money site, an exchange is created for trading tokens for dollars and ETH.
3. A smart contract is created that guarantees the automatic purchase of a token at the price in Google AdSense, if the corresponding search query is in the top1 of Google.

4. The site owner sets the initial cost of each token whose search query is in the TOP100 or lower. All tokens are issued to the exchange. While search queries are far from the top, their cost is minimal and increases as they advance in serp. Tokens are bought by seo experts and speculators.

Right... but that's not SEO that's PPC. And Google has literally no incentive or reason to put something like that on a blockchain.

The list of keywords is converted into tokens not by Google, but by a marketing Agency for website promotion. I, you, can provide such services on the market. Anyone. This is just a new format for promoting sites using thousands of freelancers or site owners whose subject matter fits the site being promoted (to build a link)
This is a way to make money on speculation as well. This is creating a community around the exchange, this is ieo.

This is nonsense. There's no reason to use a blockchain for this.

The blockchain is needed to guarantee payment for the token. Payment is guaranteed by the smart contract. People won't believe the agreement. And how will you create legal documents with thousands of freelancers who will buy the token? The technology of the blockchain so it is good that there is no human factor. This is the maximum protection for the participants of the transaction. I do not know about you, but in Russia they do not believe even signed agreements. The courts do not guarantee the execution of the court's decision.

So that you understand in Russia:
Trust in the judicial system 20%
Trust in smart contract 80%
