Although the two come from the same branch, it is important to know that they differ in multiple things. First of all, online SEO is in charge of making the content relevant or eye-catching. In other words, that the content or what is your page is compatible with Google’s organic search engines so that there is greater optimization. This is mostly seen in the written content, as well as the keywords, the speed with which the page interface opens, the reviews left by the user, among many other things that can also be reflected in the URL. Have you noticed that some pages look better on the computer than on your phone? These problems should be taken care of by online SEO strategy. While offline SEO takes care of the technical part, such as the coding of the page, what happens on the outside, social media campaigns to attract traffic to the website, advertising, among many other things. Both are necessary at the same time to create a good SEO strategy. All these things add up for a website to work properly and be a reliable source for internet users.
