Snippets by IsItWP

Are you looking for a way to remove stop words from your URLs? While there’s probably a plugin for this, we have created a quick code snippet that you can use to improve the SEO by automatically removing short words from URL in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

add_filter('sanitize_title', 'remove_short_words');

function remove_short_words($slug) {
    if (!is_admin()) return $slug;
    $slug = explode('-', $slug);
    foreach ($slug as $k => $word) {
        if (strlen($word) < 3) {
            unset($slug[$k]);
        }
    }
    return implode('-', $slug);
}

    […] to Kevin Chard for these awesome […]

  2. Well the idea is that if you remove words like “The, and, but, is, it,” etc, since they don’t have any real SEO value. However the above snippet was updated to remove only a list of words rather then all words with 3 characters or less.

    Congratulations for the post!

    I adapted your code with a list of negative words separated by commas.

    Hug!****add_filter(‘sanitize_title’, ‘remove_short_words’);function remove_short_words($slug) {    if (!is_admin()) return $slug;    $slug = explode(‘-‘, $slug);    foreach ($slug as $k => $word) { //keywords false $keys_false = ‘a,ao,aos,as,ate,da,de,do,das,dos,dum,duma,e,em,es,na,no,nas,nos,num,numa,o,os,que,um,uma’; $keys = explode(‘,’, $keys_false); foreach ($keys as $l => $wordfalse) { if ($word==$wordfalse) { unset($slug[$k]); } }    }    return implode(‘-‘, $slug);}

    1. Great snippet Alexandre. Email me so I can  set you up as an author for the snippet.

    this is bad for vietnamese

    1. This is true Trieu Quang Khan, I’m going to publish an updated version that will let users define words that will get removed from the slug.

        Great.

  6. Does it exclude 3 letter words? The write up implies it does by including the words but and and, but the screenshot shows seo still there in the URL? Presume it is the condition in line 6 that needs changing. Could removing 3 letter words be too drastic as it could remove words required for the URL to make sense? who, cup, bar, win, end, seo(!) etc.. (which could then have a negative rather than positive effect on seo?)
    Cheers.
    David.

    1. This is true, one modification I could do to this snippet would be to create a list of words that it should remove. This way it would not remove words that may be important to the SEO of the site.

  7. Do you think this is important for SEO? Why?

    Thanks
    Teo

    1. The more words you have in the URL Google will weight what could be important words less. Since the if, and, the, is, are, etc are not as important as other words this script will remove them.
