Although an image is worth a thousand words, the text is fundamental, especially in the network of networks, since the King of search engines Google what most values (indexes) is the textual content. There are companies, media and even individuals who need informative content. The best example could be blogs. Lack of time, ignorance of certain subjects or the search for a more professional product drives the need to put oneself in the hands of someone who can provide adequate content.
Even if what you are looking for is to improve the positioning of your website or your blog in the most important search engines, you should know that what is most valued is the content.
You must bear in mind that it will be essential to arouse the interest of the reader, be original, demonstrate that the subject matter is adequately known, present a text with good spelling and semantics and periodically update the contents. Constant updating will attract more visits and therefore the chances of getting more customers will increase. However, this content creation is a medium and long-term strategy that requires a lot of perseverance and patience, but if it is done properly, it will revert to a future benefit.
