<p>A 404 page is what a user sees when they try to reach a non-existent page on your site (because they’ve clicked on a broken link, the page has been deleted or they’ve mistyped a URL).</p>
<p>While the standard 404 page can vary depending on your web host, it doesn’t usually provide the user with much useful information and users may just surf away from your site. Therefore, Google recommend creating a custom 404 page that provides the user with more information about your site and its content.</p>
<p>The Google 404 widget is a quick and easy way to embed a search box on your custom 404 page and provide users with useful information designed to help them find the information they need. Where it can, the Google widget will also suggest other ways for the user to find the information they need, thus increasing the likelihood that they’ll continue to explore your site.</p>
<p>For best results, you should set up a <a href="http://www.google.com/webmasters/" title="Google" rel="nofollow ugc">Google webmaster account</a> and submit an XML sitemap of your blog to ensure the Google 404 widget works effectively.</p>

<h3>What are 404 errors?</h3>
<p>As you probably know, incoming links play important role in ranking well in Google and other search engines. Therefore you should ensure that every incoming link leads to one of your valid pages on your blog. This may be a challenge because your website is dynamic and it changes every day:</p>
<ul>
<li>you might remove or unpublish posts or pages;</li>
<li>you might change your URL structure on your blog;</li>
<li>links may brake because of technical misconfiguration;</li>
<li>a webmaster might add your link in their posts with a typo;</li>
<li>a visitor may simply mis-type your post’s URL</li>
</ul>
