Googlebot couldn't crawl this URL because it points to a non-existent page

Question

Googlebot couldn't crawl this URL because it points to a non-existent page. Generally, 404s don't harm your site's performance in search, but you can use them to help improve the user experience. this error occur in following urls.

how can i solve it..

Answer 1

check and see which page links to these pages. maybe your website's domain had a previous owner who had a webpage, and there are some inbound links pointing to that old website. this is something you can't control, if thats the case you should do a redirect on these pages to your start page. Do this with your .htaccess file:

ErrorDocument 404 /index.html

some things to check that may produce malformed urls and is under your control:

• your paging code in search results and/or categories of products/services/content
• your sitemap

i also had a similar experience, in one of my websites i had this scheme:

example.com?category=1

example.com?category=2

example.com?category=3

and in webmaster tools i was getting random strings:

example.com?category=xxcCzxvsd

in my analytics nobody (except googlebot) ever visited example.com?category=xxcCzxvsd. I couldn't find the source of this, so there is a strong chance the problem is in google's side.
