The site owner chose to hide the description of the page. WordPress?

Question

Search Engine Optimization

Good day!
After installing the engine and theme, during the development of the site, the option "Ask search engines not to index the site" was enabled, and after the work was completed, the option was disabled. But Yandex writes that: "The site owner chose to hide the description of the page" - please tell me whether it is necessary to make changes in the robot.txt file or whether it is necessary to wait (3 days have passed since the "Ask search engines not to index the site" option was disabled) for some time?

Answer 1

"3 days have passed"
Of course you have to wait. In Yandex, this inscription will disappear in the period from 3 weeks to a month and a half. It is very inert + your site is new, which means that Yandex rarely visits it at first, up to 1 time per week and a half. Whom, updating the Yandex search results index does not occur daily, but every 3-4 days, or even once a week.
In the robots.txt file, be sure to write the directive
Host: yourdomain.ru
