The Invalid JSON error in WordPress occurs only if WordPress is not able to interpret the given code correctly. The Adsense code snippet for Adsense ads is a pure HTML code, but sometimes the Block Editor of WordPress does not recognize it as a pure HTML and hence causing the issue.
In order to solve the “Google AdSense code Invalid JSON error“, just follow the following steps to create a shortcode for Adsense HTML code:
- Use the given code to make a shortcode key for the “functions.php file of WordPress”:
function add_adsense_codes_shortcode() {
$string .= ‘your adsense code here’;
return $string;
}
add_shortcode(‘show_ad_here’, ‘add_adsense_codes_shortcode’);
- Just copy the Adsense code and paste that code in the place of ‘your AdSense code here’.
- Now open your WordPress Theme File Editor, and now select your Child theme or Parent theme, and then select “functions.php”, scroll down and select the new line and paste your created code as shown above.
- Now whenever you want to place your Google Adsense Ads, just paste [show_ad_here] and it will start showing ads on your posts and pages.
Note– [show_ad_here] is your shortcode as in the above-given code, you can see that we have declared the shortcode as [show_ad_here]. In fact, you can change this line and can give any shortcode name of your own choice like ‘advertisement1’, and then use the shortcode as [advertisement].
For all your Adsense codes, you have to create shortcodes in the fucntions.php file with the same code but keep in mind to change this line “adsense_codes_shortcode”, you cannot use this shortcode declaration multiple times, but have to change its name at two places in the above-given code. You may give it any name like “adsense_codes_shortcode1”.
