How to add breadcrumbs to WordPress website without plugin

Breadcrumbs

It is also know as “breadcrumb trail” is a navigational aid that allows visitors to understand their current location in the context of a website.
There are a number of benefits to using breadcrumbs on your site:

Usability: It gives users an intuitive means of browsing through your site.
Easy to backtrack: If your site is made up of many layers then breadcrumbs can make navigating through them far easier.
Context: Breadcrumbs instantly give a vistor an idea of how the page they have landed on relates to the rest of the site.
SEO: Google will interpret your breadcrumbs and add them to the search engine results page.

For a WordPress beginner there are lot of plugins available for breadcrumbs and easy to integrate.

There is also an alternate way to show breadcrumbs on your website without any plugin. Add the below code in functions.php file of your current active WordPress theme and follow the steps accordingly.

1. functions.php

function codebuddy_breadcrumbs() {  
   /* === OPTIONS === */

  $text['search']   = 'Search Results for "%s" Query'; // text for a search results page
  $text['tag']      = 'Posts Tagged "%s"'; // text for a tag page
  $text['author']   = 'Articles Posted by %s'; // text for an author page
  $text['404']      = 'Error 404'; // text for the 404 page
  $showCurrent = 1; // 1 - show current post/page title in breadcrumbs, 0 - don't show
  $showOnHome  = 0; // 1 - show breadcrumbs on the homepage, 0 - don't show
  $delimiter   = ' &raquo; '; // delimiter between crumbs
  $before      = '<span class="current">'; // tag before the current crumb
