I noticed that in webmaster tools that Google indexed 40K of "index of" pages, ie:
I have lot of image galleries and they are stored by Wordpress default uploads folder:
/wp-content/uploads/cars/ferrari/.... /wp-content/uploads/cars/fiat/.... /wp-content/uploads/cars/audi/.... ...
There is lot of subdirectories and at final folder are image files, jpg files. So now in webmaster tools for all that 40K pages I have "Not mobile-friendly".
I turned in .htaccess
Option -indexes and google start to notify me about:
Googlebot for smartphones found an increase in authorization permission errors
So Im afraid that Google will give me bad reputation in any case. If I leave those "index of" pages he will give me bad Mobile Friendly reputation...and If I put in .htaccess
Option -indexes I will got 40K of 403 or 404 pages and he can also understand this very bad?
