Performance & Security

Images


WordPress Updates

  • Disable All WordPress Updates — prevents unwanted changes when themes, plugins and core updates occur.
  • WP Rollback — roll back any plugin or theme to a previous version. Because newer isn’t always better!

Website Migration


Broken Links

Page Design & Layout


Custom Pages


Widgets


Search Functionality

  • Ajax Search Lite — add a live search form to your site with filters (it’s used on this site).

Image Galleries


Map Selector

  • HTML5 Maps — a map depicts regions (countries, counties etc) which takes the user to a unique URL when clicked. Very simple, but works well.
  • WP Google Maps — create custom Google Maps with high-quality markers containing locations, descriptions, images, and links.

Mobile Compatibility


App Creation


Communication


Comment Sections

  • Disqus for WordPress — it has poor reviews, but I personally think it’s very neat.
  • Comments – wpDiscuz — light-weight and reliable. Recommended if your site is subjected to unwanted ads from Disqus.
  • Rich Reviews — show your ratings/reviews as rich snippets in SERPs.

Contact Forms

  • Contact Form 7 — simple functionality. Very popular plugin.
  • WPForms Lite — drag & drop form builder. Equally as good as the above plugin.

Search Engine Optimisation


Writing Tools

  • Yoast SEO — write better content and full optimise your entire WordPress site.

Additional Features

Newsletters


Connectivity

Anchors

  • Scroll to Anchor — jump to any section of the page, with a smooth scrolling animation.

Pullquotes

  • Perfect Pullquotes — display striking quotes in your posts (looks much better than the standard ones).
