From the previous note we learned about the concept of SEO. We also know what a search index is and how it is updated using search robots.
In an ideal world, a search robot should load a page, analyze its content, and create a list of keywords that best correspond to the content. (By the way, just in case, keywords - these are, roughly speaking, search phrases, I hope there are no questions about this. =)) But we understand that it is not possible. In order to do this, a search robot must have human thinking, a semblance of intelligence. (Although, despite everything, robots are very smart, so don't underestimate them, but more on that later).
Despite the fact that most of the time I still program, I decided to touch on such a slippery topic. With this note, I will start a series of posts about the so-called SEO. I do not claim one hundred percent correctness or completeness (moreover) of the material presented. In general, these notes are actually initially addressed to one person, but as practice shows, they may be useful to a larger number of readers.
