How to Fix 404 Soft Errors in WordPress to Avoid Google Penalty

Being the most popular CMS (Content Management System), WordPress is still not completely out of fault. One such faulty part of WordPress is the 404 Soft Error pages. Did you know that this 404 Soft Error can invite a Google penalty for your website or blog? If not, read how to fix 404 Soft Errors in WordPress to avoid Google penalty.

What is 404 Soft Error?

According to the Google Webmaster guidelines, a page with 404 Soft Error is actually the page which has no content but the server does not returns a 404 HTTP response for the page. Just because you show a “404 Not Found” text into the content part of the page does not mean that it is a 404 page. Rather, you should call it as a 404 Soft Error page until it returns a 404 status code as the server response. Learn more about 404 Soft Error from Google Webmaster Tools Help Page.

When does 404 Soft Error Happen in WordPress?

The 404 Soft Errors happen with WordPress mostly in two cases:
Case 1. If you search something that does not exist at a WordPress site using the WordPress internal search feature, it returns a page saying “Sorry, there is no content matching with your search query” or some thing like that. Even, in some theme, it shows “404 Not Found” against any non-existing search query.
But if you see into the server response code, you will get a 200 OK response for that search result page instead of 404 Not Found. It is not recommended by Google, as the crawlers can not decide that the page does not exist.
Case 2. If you have any category(s) or tag(s) without having any post, the link for those categories or tags returns the 404 Soft Error page. Y0u can take the “Uncategorized’ category as an example. If you browse, you should get the page where the result is empty but the server response is 200 OK.
Why does Google Charge Penalty to the Sites having 404 Soft Error Pages?
Google always prefers to show relevant pages to the visitors. If any of your pages does not exist that the visitors are searching for, you should return a 404 Not Found page with a 404 Not Found server response. If you do not follow this; for instance, if you redirect them to your home page or somewhere else or you show an empty page without proper server response code, you are actually not maintaining the Google Webmasters Guidelines. This may invite a Google penalty for your site.
Some SEO experts suggest to block search pages from search engines. But we do not inspire you to do so. Blocking search boats can damage your site more deeply.

How to Fix 404 Soft Errors in WordPress

As I stated earlier that WordPress generates 404 Soft Errors for its internal searches (for non-existing query) and the archive pages which do not have any post, here is how to convert those Soft Error pages into proper ‘404 Not Found’ pages.
You can do it by adding a small snippet of codes at your themes function.php template and calling the function from the Search and Archive page template. I have written the code for Genesis child themes though. Those who are using Genesis child theme can add the following codes directly into their child theme’s function.php file. The others can modify this code slightly to implement with non-Genesis themes.

function force_to_404()
if ( have_posts() )
return FALSE;
header( 'HTTP/1.0 404 Not Found' );
$GLOBALS['wp_query']->is_404 = TRUE;
return TRUE;
function oxh_404soft(){
echo genesis_html5() ? '<article class="entry">' : '<div class="post hentry">';
printf( '<h1 class="entry-title">%s</h1>', __( 'Not found, error 404', 'genesis' ) );
echo '<div class="entry-content">';
if ( genesis_html5() ) :
echo '<p>' . sprintf( __( 'The page you are looking for no longer exists. Perhaps you can return back to the site's <a href="">homepage</a> and see if you can find what you are looking for. Or, you can try finding it by using the search form below.', 'genesis' ), home_url() ) . '</p>';
echo '<p>' . get_search_form() . '</p>';
else :
<p><?php printf( __( 'The page you are looking for no longer exists. Perhaps you can return back to the site's <a href="">homepage</a> and see if you can find what you are looking for. Or, you can try finding it with the information below.', 'genesis' ), home_url() ); ?></p>
echo '</div>';
echo genesis_html5() ? '</article>' : '</div>';
// Force 404 Soft Errors to 404 Not Found Errors
function oxh_soft_404(){
if ( force_to_404() ) {
remove_action( 'genesis_before_loop', 'genesis_do_search_title' );
add_action( 'genesis_loop', 'oxh_404soft' );
return; //here it will stop any further process so soft 404 will not occur
elseif(is_archive()){if ( force_to_404() ) {
add_action( 'genesis_loop', 'oxh_404soft' );
return; //here it will stop any further process so soft 404 will not occur

Once you configured your WordPress by above way, you can check the results for which the 404 Soft Error pages were getting generated.
