This question already has an answer here:
I have a website which is 2 years old and it is simple PHP pages.
I had set up Google Analytics and Google Webmaster Tools for it.
Just last week I removed that PHP website and installed a new WordPress website. I just created pages with the old site's content and also add few new images.
The issue is: when I logged into my Google Webmaster Tools account there were 170 404 not found errors!
How do I resolve the error messages saying 404 not found?
How can I remove not existing page links from Google Webmaster Tools?
Will it affect my website traffic?
