How long does it take to notice SEO results?
What we have noticed is that the changes that are noticed the fastest, even after 3-4 days, are changes of a technical nature. This means that if your website has problems of this type, it would be best to fix them as soon as possible. These problems are usually solved by changing the code of your website.
If it's about changing content or adding new content, the ranking changes also depend on the popularity of your website, that is, how quickly Google will take that content into account. A good example are news websites, the content of which appears on Google after just a few minutes.
Presentations, stores, and other similar websites generally have a period of 2-3 months in which Google and other search engines still decide which is the more permanent position of your content individually, and for which keyword.
Of course, it all depends on many factors.
