Do 404s hurt my site?

Webmaster level: Beginner/Intermediate So there you are, minding your own business, using Webmaster Tools to check out how awesome your site is... but, wait! The Crawl errors page is full of 404 (Not found) errors! Is disaster imminent??
Fear not, my young padawan. Let’s take a look at 404s and how they do (or do not) affect your site:

Q: Do the 404 errors reported in Webmaster Tools affect my site’s ranking?

A: 404s are a perfectly normal part of the web; the Internet is always changing, new content is born, old content dies, and when it dies it (ideally) returns a 404 HTTP response code. Search engines are aware of this; we have 404 errors on our own sites, as you can see above, and we find them all over the web. In fact, we actually prefer that, when you get rid of a page on your site, you make sure that it returns a proper 404 or 410 response code (rather than a “soft 404”). Keep in mind that in order for our crawler to see the HTTP response code of a URL, it has to be able to crawl that URL—if the URL is blocked by your robots.txt file we won’t be able to crawl it and see its response code. The fact that some URLs on your site no longer exist / return 404s does not affect how your site’s other URLs (the ones that return 200 (Successful)) perform in our search results.

Q: So 404s don’t hurt my website at all?

A: If some URLs on your site 404, this fact alone does not hurt you or count against you in Google’s search results. However, there may be other reasons that you’d want to address certain types of 404s. For example, if some of the pages that 404 are pages you actually care about, you should look into why we’re seeing 404s when we crawl them! If you see a misspelling of a legitimate URL (www.example.com/awsome instead of www.example.com/awesome), it’s likely that someone intended to link to you and simply made a typo. Instead of returning a 404, you could 301 redirect the misspelled URL to the correct URL and capture the intended traffic from that link. You can also make sure that, when users do land on a 404 page on your site, you help them find what they were looking for rather than just saying “404 Not found."

The HTTP 404 Not Found Error means that the webpage you were trying to reach could not be found on the server. It is a Client-side Error which means that either the page has been removed or moved and the URL was not changed accordingly, or that you typed in the URL incorrectly. It definitely effects your keyword ranking in search engines. The error should be recovered.

Yeah surly 404 URL error effects on keyword ranking, as the page a user or client is trying to access is not on the server. That mean page have been removed or has a changed url. You should fix it for better keywords ranks.

404 errors not directly effect the ranking but user experience is the main part of SEO nowadays the reason why it is good to re-direct them to the appropriate pages for better user experience to enhance SEO performance. But if those pages have back links then it is highly effective to pass the link juice to the pages by redirecting them

Yes, 404 errors definitely produce bad effect on users as well as for crawler. Search engine give high rank to precise and informative sites. 404 errors prevent to users and crawler to reach on web page so I suggest to fix all 404 errors and remove unwanted web page those contained with it.
