Performing adult SEO is difficult. Over the years, so much has changed and its not as simply as it used to be 10 years ago. Updates are always changing how escort SEO needs to be performed.
You need to understand user intent, have a user friendly website, have great EAT content, a strong trusted domain and high quality links. You have to be the best in all departments.
Even most recent updates have affected escort websites. The helpful content update and review updates have caused guides like https://sexcityguide.com/ to start to outrank agency and directory websites.
My advice, don't worry about rankings in the short term. Build a brand and in the long term you will always be onto a winner.
