There are a few different factors that will determine how quickly (or slowly) results will come. This list includes, but isn't limited to:

  • How much content you create

  • The quality of the content

  • How the content resonates with your audience

  • If you're a big or small site with strong or weak domain authority

A large site could possibly see results in a couple of days if a search engines is crawling their site regularly. Smaller sites will most likely take longer because they get crawled less frequently. Wait at least a week, but probably closer to a month, before you consider changing your SEO strategy - a bit longer if you're brand new to SEO.
