SEO

True\SEO generates JSON-LD structured-data scripts for common schema.org types — articles, recipes, products, organizations, breadcrumbs — plus a complete schema "graph" tying a page's structured data together. Drop the output inside <head> and search engines pick it up.

Per-page JSON-LD

The jsonLD() method returns a ready-to-embed <script type="application/ld+json"> tag for the supplied schema type:

use True\SEO;

$seo  = new SEO;
$html = $seo->jsonLD('recipe', [
    'name'        => 'Chocolate Cake',
    'description' => 'A delicious chocolate cake recipe',
    'author'      => 'John Doe',
]);

echo $html;

Produces:

<script type="application/ld+json">
{
    "@context": "http://schema.org",
    "@type":    "Recipe",
    "name":     "Chocolate Cake",
    "description": "A delicious chocolate cake recipe",
    "author":   "John Doe"
}
</script>

Supported types

  • recipe
  • article
  • organization
  • website
  • webpage
  • blogpost
  • breadcrumbs
  • store
  • homeandconstructionbusiness
  • product

Breadcrumb data

If you'd rather not author breadcrumb entries by hand on every page, generateBreadcrumbs() derives them from the request URI. Pass an INI file to override the auto-generated labels:

; app/data/breadcrumbs.ini
/             = "Home"
/contact.html = "Contact Us"

$crumbs = $seo->generateBreadcrumbs(BP.'/app/data/breadcrumbs.ini');
print_r($crumbs);
// => [[ 'name' => 'Home', 'url' => '/' ], ...]

Feed the array straight into jsonLD('breadcrumbs', $crumbs) or into the schema graph below.

The schema graph

schemaGraph() emits a single @graph JSON-LD block that ties together the WebSite, WebPage, Organization, and BreadcrumbList for one page — exactly the bundle Google's structured-data tools expect to see:

$info = (object) [
    'url'               => 'https://example.com',
    'title'             => 'Example Website',
    'description'       => 'An example website description',
    'site_logo_url'     => 'https://example.com/logo.png',
    'site_logo_width'   => 300,
    'site_logo_height'  => 100,
    'site_logo_caption' => 'Example Logo',
    'datePublished'     => '2023-01-01',
    'dateModified'      => '2024-01-01',
    'social_media' => [
        'https://facebook.com/example',
        'https://twitter.com/example',
    ],
    'breadcrumbs' => [
        ['name' => 'Home',  'url' => '/'],
        ['name' => 'About', 'url' => '/about/'],
    ],
];

echo $seo->schemaGraph($info);

Where to render it

Echo the returned strings inside <head>. If you already use the view's built-in breadcrumb support or {jsonld} blocks, reach for those first — they keep the markup with the page meta. Use True\SEO when you need types or graph shapes the view layer doesn't cover.
