Grammar incremental change signal of search engines
If the level of grammar correctness increases over time it is a clear insight that tells the search engine that there are people behind this website, blog, or webpages that try to make it better not bot and smart algorithms that try to trick search engine algorithms.
Given that the grammar correctness improvement is a signal that can tell the search engine that the web content is maintained by real persons, it can be better to start making mistakes and to correct them back over time to tell the search engines that you are a human, not a bot. But because there is always a but a smart SEO algorithm can also imitate this behavior of incrementally correcting the content grammar. if This smart SEO algorithm is run by smart people like me who care about clean safe and always improving internet content that’s great but if they don't care it is a bad thing. That’s why I committed to never sell this kind of technology.
This grammar incremental correctness signal is one of the components of search engine architectures and algorithms.
