I changed my permaink twice, due to which now I am getting 404s, but I have finally decided a suitable permalink structure for my website, which will be permanent,
But my question is, what to do with the 404 I am getting?
I have around 400-500 404s, what should I do,
I know I can remove it from google webmaster by inputting single URL at a time, but for 400 urls, I cant keep on doing that,
Is their any other way?
