AuditySEO

AuditySEO Canonical Manager gives you complete, granular control over the canonical URL of every page on your WordPress site: posts, pages, custom post type entries, taxonomy terms, archive pages, and even the pagination pages WordPress generates automatically.
Missing or incorrect canonical tags are one of the most common technical SEO problems on WordPress sites. They let search engines index duplicate versions of the same content, split your ranking signals across multiple URLs, and waste crawl budget on pages that should never compete for the same keywords. AuditySEO Canonical Manager fixes this at the source, so every URL on your site points search engines to the page you actually want ranked.
<h4>Free features</h4>
<ul>
<li>Lists pages, posts, custom post types, terms and archives in a dedicated AuditySEO Canonicals admin screen.</li>
<li>Shows the default canonical URL that WordPress (or your SEO plugin) would output for each item.</li>
<li>Detects content pagination created with the <code></code> tag.</li>
<li>Detects pagination of the posts page (<code>page_for_posts</code>) based on the number of published posts and <code>posts_per_page</code>.</li>
<li>Detects pagination of taxonomy term and archive listings.</li>
<li>Lets you set a custom canonical URL per item and per pagination page.</li>
<li>Applies your overrides through the canonical filters of WordPress core, Rank Math and Yoast SEO.</li>
<li>Rewrites the <code><link rel="canonical"></code> tag in the final HTML output as a fallback for themes, caches and plugins that print a canonical outside of those filters.</li>
<li>Imports and exports canonical overrides via CSV, with a dry-run preview before bulk changes are applied.</li>
<li>Validates canonical URLs when you save them (HTTP status, redirects, noindex, external domain) without blocking the save, and flags the affected item with the reason until it is fixed.</li>
<li>Filters the editor by status, override state and pagination.</li>
</ul>
<h4>Pro features</h4>
Upgrade to AuditySEO Canonical Manager Pro to unlock:
<ul>
<li>History & restore – every change to a canonical override is recorded with the user and date, and can be rolled back with one click.</li>
<li>Automatic canonical fixes, applied site-wide:
<ul>
<li>Replace pagination canonicals that point to page 1 with each page’s own self-referencing URL.</li>
<li>Strip tracking parameters (utm_*, gclid, fbclid, msclkid, and more).</li>
<li>Strip display-variant parameters (print, amp, output, format, replytocom, and more).</li>
<li>Force the canonical to always match the requested URL exactly, including its query string.</li>
</ul>
</li>
</ul>
The free version is fully functional on its own and does not require the Pro upgrade to manage canonical overrides, detect pagination, validate URLs or import/export CSV files.

Dooplee Duplicate Content Checker displays the last 10 blog posts and a Google custom search engine you use to monitor your content. Scrapers and “auto-blogs” take content from your site that is indexed by Google. This harms your search engine rank, especially when you have multiple people scraping your blog. This simple tool helps you monitor your blog’s content from within the admin panel.
Duplicate content affects your Google rank, but you can take action to fight the content thieves. The scrapers attempt to gain Google rank from your work, so to protect your own Google rank and your income, you can use the DMCA system to remove the content. The form you fill out requests an evaluation of the stolen content, and we return an evaluation to you within 48 hours.
The plugin installs in the admin area in the Tools section. It loads the last 10 blog posts, but you can use it to check older blog posts as well. If you find duplicate content, use the form to fill out a DMCA request, and we will evaluate the situation and tell you what we can do to help you remove the content. In most situations, we can at least have the content removed from Google as well as Bing and Yahoo to make the stolen content useless to the thief. However, our first attempt is to have the content removed from the host server.
For more information about duplicate content and how it affects your site, visit http://dooplee.com/blog or visit http://dooplee.com to start the DMCA takedown notice process. We also offer monthly maintenance service to monitor stolen content for you, so you can keep writing instead of tracking scrapers. Please use the contact form on our blog if you have any issues or feedback for this plugin.
