Answer After installing WordPress plugins we have consider the flowing questions that may arise they are:
• Do JavaScript-based administrative functions still work?
• Does your site slow down?
• Does the plugin add warnings to the top of every administration screen? If so this plugin needs to be configured or just invitations to buy things and/or promote the company on your social media networks.
• Does it add spam links to your source code?
• Check the site in another browser, one where you are not logged in to WordPress
• Does it put ads on your admin screens—even those for other plugins’ settings.
• Does it add a Dashboard widget full of links to the developer’s other products?
• Does it add text to your site’s footer without your permission?
• Does its settings screen blend in with the WordPress Dashboard, or does it look completely different.
