Recommendation: For large websites, the directory structure should be controlled below 3 - 4
For medium-sized websites, the catalog is strictly controlled below 3
For small websites, the catalog is strictly controlled below 2.
For the relative position of the dedecms URL optimization directory, you can choose another default in the cms root directory, and then click the naming rule of {typedir}/{Y}/{M}{D}/{aid}.html of the advanced options article to remove all/after {Y}. This is the optimization of dedecms URLs. Everyone is welcome to pay more attention.Beijing seo
