1, no top-level domain name.
Internet companies usually configure a second-level domain name or a multi-level domain name for free websites instead of a top-level domain name. If you really do a website, the domain name must be a top-level domain name, mainly. Com domain name. For example, yiqnet.com is a top-level domain name, while m.yiqnet.com is a second-level domain name.
Moreover, the ownership of the domain name must be yours. It is impossible to do this for free, because the domain name fee alone will cost tens of dollars, even the network company can't save it.
2. There is no independent space.
Intelligent website building is usually to build a system in a server, through which many derivative websites under this server can be managed. Every website has no independent space. A regular website will open an independent virtual host (space for short) or an independent cloud server for you. This is something that companies that do websites for free can't provide.
3, unable to record and promote.
Since you use a second-level domain name, the ownership of this second-level domain name must belong to the company that makes the website, not you, so you can't file this domain name. Since you can't put it on record, it means that your website can't meet the promotion methods such as baidu promotion and 360 promotion, and the website has almost no development prospects.
4. Advertising links in the website
Free websites do allow you to use them for free, but their advertising links will definitely be added to the website (usually at the bottom of the website). This will seriously affect the corporate image of the company.

3. The cost of website production and post-maintenance varies according to the requirements, generally ranging from several hundred yuan to tens of thousands of yuan.
