When running a an audit on a website (yours, a competiror, or client), you can often find yourself going to around ten or more websites to run tests (Inquiries). 
At each of these you then paste the same URL and run it’s test and repeat for each one. Most of these services use the GET HTTP request method. You see these as the ?q= part in <a href="https://duckduckgo.com/?q=ecotechie" rel="nofollow ugc">https://duckduckgo.com/?q=ecotechie</a>.
I decided to write this plugin so I could input a URL once and run all of these tests more easily. No need to hunt down the website addressses or even leave the WordPress admin dashboard!
Features:
<ul>
<li>Use any valid URL for testing, it doesn’t have to be the current site the plugin is installed on.</li>
<li>Add or remove websites to use for tests (Inquirers).</li>
<li>Sortable by filter types like SEO, Speed, Security, etc. Or create your own tags…</li>
</ul>
