Ayuda WordPress

This plugin is now part of <a href="https://wordpress.org/plugins/native-aeo-pack/" rel="ugc">Visibility</a>.
Everything this plugin does is bundled into Visibility, a single lightweight 
plugin that unifies the three AyudaWP “Native SEO” plugins (Meta Tags, NoIndexer 
and Sitemap Customizer) into one, built entirely on WordPress native features.
This plugin still works and stays available, but new features and fixes now go 
into Visibility. If you’re setting up a new site, install Visibility 
instead of this one.
<h4>Moving to Visibility</h4>
<ol>
<li>Install and activate Visibility.</li>
<li>Open its settings, enable the modules you need (Meta Tags, NoIndex, Sitemap) 
and set your site-wide options.</li>
<li>Deactivate this plugin. Visibility reminds you while both are active, 
because running both at once prints duplicate tags.</li>
<li>Check your page source: you should see a single set of tags, from Visibility.</li>
</ol>
Your settings are not imported automatically in this first version. Site-wide 
options take a minute to re-enter. For per-post values (individual noindex/nofollow, 
custom titles and descriptions, Open Graph images), deactivate this plugin rather 
than deleting it, so the data stays in place for the automatic importer planned 
for a future Visibility release.
<h3>External services</h3>
This plugin connects to Gravatar (operated by Automattic Inc.) to check whether the post or page author has a public Gravatar avatar, so it can be exposed in Open Graph tags (<code>og:image</code>) and in Person JSON-LD (<code>image</code>) for E-E-A-T.
What data is sent and when:
<ul>
<li>When a singular view (post, page, custom post type) is rendered and the Open Graph module is active, and there is no per-post <code>og:image</code>, no featured image, no WooCommerce gallery image and no inline image in the content, the plugin sends an MD5 hash of the lowercased and trimmed author email to <code>https://www.gravatar.com/avatar/{hash}?d=404</code> via <code>wp_remote_head()</code> (HEAD request, no body) to check whether a Gravatar exists for that author.</li>
<li>When an author archive is rendered and the Person schema module is active, the same probe is performed for that author.</li>
<li>The original email address is never sent — only an MD5 hash, which is the standard Gravatar lookup mechanism.</li>
<li>The result (found / not found) is cached for 24 hours in a transient (<code>nseo_gravatar_{hash}</code>) so subsequent page loads do not hit Gravatar again.</li>
</ul>
This service is provided by Automattic Inc.:

No other external services are used. The plugin makes no other HTTP requests, sends no telemetry and stores no data outside your own WordPress database.

Native SEO Meta Tags

Now part of Visibility — meta tags, Open Graph, Twitter Cards and JSON-LD are bundled there.

CongBom

Generate most common meta tags to your WordPress site.
Open Graph (og) tag via post content and featured image:
<pre><code><meta property="og:url" content="..." />
<meta property="og:type" content="..." />
<meta property="og:title"content="..." />
<meta property="og:description" content="..." />
<meta property="og:image" content="..." />
</code></pre>
Meta description tag via post content or excerpt:
<pre><code><meta name="description" content="..." />
</code></pre>

Meta Tags Generator

It assumes that the theme's screenshot is in .png format. For smaller file size reason, I prefer using .jpg images for my theme's screenshots.

To set the record straight, .png is the preferred format, although other image formats are allowed. This is a direct quote from the Codex pages:

"Note that optionally, .jpg, .jpeg, and .gif are also valid extensions and file formats for the screenshot (though not recommended)." 

Other than that, this plugin is refreshingly small in size, and that's a good thing.

Almost there!

Automatic generate meta tags. Let your WordPress site optimize with Search engine & Social sharing.
