WPSSO Core Pro [Main Plugin]

WPSSO Core makes sure your content looks great on social and search sites -- no matter how URLs are crawled, shared, re-shared, posted, or embedded:

WPSSO Core is fast, simple, and provides complete and accurate information about your webpage content to social sites (Facebook, Pinterest, Twitter, LinkedIn, etc.), search crawlers (Google, Bing, etc.), mail and messaging apps (Facebook Messenger, iMessage, Skype, WhatsApp, etc.), and embedded objects / iframes.

Uses your existing content for meta tags and Schema markup:

There's no need to manually select meta tag names, re-enter descriptions, titles, product information, select images / videos, etc. — WPSSO Core reads your existing post, page, product, media, recipe, event, forum, and SEO content automatically, and offers fine-tuning and customization options for just about anything and everything. ;-)

WPSSO Core is also language / locale aware, which means you can customize your site information, social page URLs and Knowledge Graph for different languages.

Creates complete and accurate meta tags and Schema markup:

WPSSO Core and its optional Free add-ons offer meta tags and Schema markup for Facebook / Open Graph, Google's Knowledge Graph SEO, Google Rich Card SEO, Google Merchant SEO, Mobile Web Browsers, Pinterest Rich Pins, Twitter Cards, Weibo and many more — including complete markup for images, videos, extensive eCommerce product markup (for WooCommerce and others), mobile apps, author profile / authorship, co-authors, publisher information, local business markup, aggregate ratings, reviews, recipe information, event details, and much, much more — all from your existing content!

Includes advanced quality assurance features and options:

1. Checks for minimum / maximum image dimensions and aspect ratios.
2. Shows notices for missing and required images.
3. Verifies webpages for duplicate meta tags.
4. Validates theme header templates for correct HTML markup.
5. Checks and warns of any missing PHP modules.
6. Checks 3rd party plugin settings for possible conflicts.

★★★★★ — "What a fantastic plugin. If you want to fix all the errors in search console for structured data, this is the plugin to use. Love it." - goviral

★★★★★ — "This plugin saves me so much time, and it has really lifted my SERP rankings. Most of my keywords I now rank 1-3 position. I also noticed after about a week that my impressions have gone up at least 75%. I upgraded to the pro version which gave me even more options." - playnstocks

★★★★★ — "Yoast on steroids! As an SEO marketer, I love using Yoast for my basic on-page SEO. But Yoast only allows you to enter basic Open Graph social settings. This plugin gives you SO many more options on completing the Open Graph for Facebook, Twitter cards, Pinterest etc. If you use WordPress, I totally recommend using this plugin to help with better rankings in the SERPS!" - gregmontag

Release Schedule

New versions of the plugin are released approximately every week (more or less). New features are added, tested, and released incrementally, instead of grouping them together in a major version release. When minor bugs fixes and/or code improvements are applied, new versions are also released. This release schedule keeps the code stable and reliable, at the cost of more frequent updates.

See release early, release often (RERO) software development philosophy on Wikipedia for more information on the benefits of smaller / more frequent releases.

Version Numbering

Version components: {major}.{minor}.{bugfix}[-{stage}.{level}]

• {major} = Major structural code changes / re-writes or incompatible API changes.
• {minor} = New functionality was added or improved in a backwards-compatible manner.
• {bugfix} = Backwards-compatible bug fixes or small improvements.
• {stage}.{level} = Pre-production release: dev < a (alpha) < b (beta) < rc (release candidate).

Free / Standard Version Repositories

• GitHub
• WordPress.org

Development Updates for Pro Version

Development, alpha, beta, and release candidate updates are available to Pro version customers.

Under the SSO > Update Manager settings page, select the "Development and Up" version filter for WPSSO Core and all its extensions (to satisfy any version dependencies). Save the plugin settings, and click the "Check for Updates" button to fetch the latest / current WPSSO version information. When new Development versions are available, they will automatically appear under your WordPress Dashboard > Updates page. You can always re-select the "Stable / Production" version filter at any time to re-install the last stable / production version of a plugin.
