To fully utilize the capabilities of websites on the "Ucoz" platform, a paid version is required. This will allow for resource optimization and improve its positions in search engines. However, one of the drawbacks is the mobile version, which is only slightly better than the standard PDA, and a lot of improvements will be needed. Additionally, the presence of ads is irritating: if you don’t pay, they will be there. You will also have to wait for maintenance work to be done, as the service removes temporary sites. Paid support is also a downside, but this can be managed by asking questions on the "Ucoz" forums. As for the positives, it’s worth noting the flexible pricing policy for those looking to subscribe. The functionality is versatile, allowing for the creation of both online stores and business cards. You can choose modules for placement yourself, excluding unnecessary ones. Furthermore, there is decent SEO optimization for promotion. For those who understand coding, there is an option to edit it, but in this case, using builders loses its purpose. Overall, it’s a good tool, and the positives significantly outweigh the negatives.
