As an SEO specialist, I understand that the service that 1PS calls "Website Registration in Directories" is aimed at obtaining links for the registered site. However, 1PS has quite an unusual interpretation of the goals of this service. As a result, they do not provide any guarantee on the number of links after the work is completed. This means that there may be too few links compared to the price of the service, or there may be none at all. Personally, the links that resulted from their work turned out to be very expensive (considering the amount I paid). Unfortunately, I couldn't resolve this issue with them, as they stubbornly stood their ground - "we won't refund the money and we won't redo it." P.S. If someone tells you that a certain number of links CANNOT be guaranteed for such a service - don't believe them. With honest work, a reasonable minimum of links can be ensured.
