顺德网站定制设计怎么推广一个网站

说明：
我计划用fastapi+vue做一款在线小说系统，功能包括：

1.sql部分：1.1 mysql建表
2.后端部分：2.1 写接口 处理业务，对sql表进行处理2.2. 新增小说2.3. 新增章节2.4. 获取小说列表2.5. 获取章节列表
3.vue前端部分：3.1 小说列表，3.1.1左边分类列表，右边小说列表，3.1.12 点击分类列表，展示对应的小说列表3.2新增小说  仿照阅文作家平台，可以输入书名，简介，创建小说3.3章节列表3.3.1 获取服务端的接口，展示章节列表3.3.2新增章节3.3.3 输入章节的内容和标题，点击发布，提交章节内容3.3.4 发布章节成功后，刷新左侧的章节列表

效果图：
