YRewrite ships with `rex_yrewrite_seo` – a helper that pulls SEO data from articles (title, description, image) and renders meta tags. It also generates `sitemap.xml` and a `robots.txt` block.
YRewrite ships with rex_yrewrite_seo – a helper that pulls SEO data from articles (title, description, image) and renders meta tags. It also generates sitemap.xml and a robots.txt block.
Each article has SEO fields managed via the seo tab in the backend (article edit). They live as meta-info fields:
art_yrewrite_title – <title> override (falls back to article name)art_yrewrite_description – meta descriptionart_yrewrite_index – index, noindex, or empty (default = follow site setting)art_yrewrite_canonical_url – override canonicalart_yrewrite_image – Open Graph image filenameFor domain-level defaults (site title, description), set them per domain in YRewrite → Domains → SEO.
Place this in the <head> of your template:
<?php $seo = new rex_yrewrite_seo(); ?>
<title><?= rex_escape($seo->getTitle()) ?></title>
<meta name="description" content="<?= rex_escape($seo->getDescription(), 'html_attr') ?>">
<?= $seo->getRobotsTag() ?>
<?= $seo->getCanonicalUrlTag() ?>
<?= $seo->getHreflangTags() ?>
getRobotsTag(), getCanonicalUrlTag(), and getHreflangTags() produce full <meta> / <link> elements. They're already escaped – don't wrap them in rex_escape.
YRewrite doesn't render OG tags itself. Add them yourself using the SEO data plus an explicit OG image:
<?php
$seo = new rex_yrewrite_seo();
$ogImage = (string) rex_article::getCurrent()->getValue('art_yrewrite_image');
$ogImageUrl = $ogImage
? rex::getServer() . rex_url::media($ogImage)
: rex::getServer() . rex_url::frontend('assets/og-default.jpg');
?>
<meta property="og:title" content="<?= rex_escape($seo->getTitle(), 'html_attr') ?>">
<meta property="og:description" content="<?= rex_escape($seo->getDescription(), 'html_attr') ?>">
<meta property="og:url" content="<?= rex_escape(rex_yrewrite::getFullUrlByArticleId(rex_article::getCurrentId(), rex_clang::getCurrentId()), 'html_attr') ?>">
<meta property="og:type" content="website">
<meta property="og:image" content="<?= rex_escape($ogImageUrl, 'html_attr') ?>">
<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:title" content="<?= rex_escape($seo->getTitle(), 'html_attr') ?>">
<meta name="twitter:description" content="<?= rex_escape($seo->getDescription(), 'html_attr') ?>">
<meta name="twitter:image" content="<?= rex_escape($ogImageUrl, 'html_attr') ?>">
YRewrite auto-generates https://<domain>/sitemap.xml. To exclude an article, set art_yrewrite_index to noindex or check "exclude from sitemap" in the backend.
To extend the sitemap with dynamic entries (e.g. YForm dataset URLs), hook into the sitemap generation:
// In your addon's boot.php
rex_extension::register('YREWRITE_SITEMAP', function (rex_extension_point $ep) {
$items = $ep->getSubject();
foreach (team_member::query()->where('status', 1)->find() as $member) {
$items[] = [
'loc' => rex_yrewrite::getFullUrlByArticleId(42, rex_clang::getCurrentId())
. '?member=' . $member->getId(),
'lastmod' => date('c', strtotime((string) $member->getValue('updatedate'))),
'changefreq' => 'monthly',
'priority' => '0.6',
];
}
return $items;
});
YRewrite serves robots.txt per domain. Configure each domain's robots block in YRewrite → Domains → robots.txt. Default content:
User-agent: *
Allow: /
Sitemap: https://www.example.com/sitemap.xml
For staging environments, swap to:
User-agent: *
Disallow: /
Detect environment in your template or boot.php and switch with an extension point if you don't want to maintain separate domain configs.

getRobotsTag() / getHreflangTags() in rex_escape() – they output safe markup already. Double-escaping breaks them.art_yrewrite_canonical_url to a duplicate URL on multiple articles – Google then ignores all but one.Disallow: / in production after copying from staging.Creates, edits, and optimizes skills for Claude Code, including drafting, evaluating with test prompts, iterating on performance, and improving skill descriptions for better triggering accuracy.
