🤖 Send Sitemaps To Search Engines

According to the sitemaps protocol, search engines should have a url that allow you to inform them about your new sitemap files. like: <searchengine_URL>/ping?sitemap=sitemap_url

use Melbahja\Seo\Ping;

$ping = new Ping;

// the void method send() will inform via CURL: google, bing and yandex about your new file
$ping->send('https://example.com/sitemap_file.xml');

Indexing API

This is the first PHP library to support the new search engines indexing API (aka indexnow.org).

use Melbahja\Seo\Indexing;

$indexer = new Indexing('www.example.cpm', [
    'bing.com' => 'your_api_key_here',
    'yandex.com' => 'your_api_key_here',
]);


// index single url.
$indexer->indexUrl('https://www.example.com/page');

// index multi urls.
$indexer->indexUrls(['https://www.example.com/page']);
