SEO

Meta tags and indexing

• On pages with selected filters or a search query, the snippet adds <meta name="robots" content="noindex, follow">. Pagination pages without filters stay indexed. Turn this off with &noindexFiltered=`0`.
• AJAX responses are sent with the X-Robots-Tag: noindex, nofollow header.
• Pagination links and the remove icons on selected filters are real links with href. A search bot can follow them without JavaScript.
• For <title>, H1, description and <link rel="canonical">, use the placeholders mscatalyst.title, mscatalyst.h1, mscatalyst.description and mscatalyst.canonical, see Page placeholders.

Title, H1 and description templates

The templates are set in system settings and apply when at least one filter is selected:

Setting	Default
mscatalyst_seo_title_filtered	—
mscatalyst_seo_h1_filtered	:
mscatalyst_seo_description	. . Найдено:

Placeholders: , (selected values and the search query), , .

Modes

The mode is set by the &seo property, or by the mscatalyst_seo_mode setting if the property is not set.

Mode	What it does
off	No friendly filter URLs, the URL has GET parameters.
native	Built-in friendly filter URLs. The plugin parses them on OnPageNotFound.
seofilter	A bridge to SeoFilter on MODX 2.
both	SeoFilter and built-in URLs together.

Built-in friendly URLs

With &seo=native`` every selected filter becomes a URL segment:

/catalog/vendor-nike/color-krasnyy-or-siniy/price-1000-2000/

A segment starts with the facet key. Values come from the labels and are transliterated to Latin. Several values are joined with -or-. Here krasnyy-or-siniy is the transliteration of "красный" (red) and "синий" (blue). For a range, the "from" and "to" bounds follow the key.

The msCatalystSitemap snippet outputs a sitemap of landing pages:

[[!msCatalystSitemap? &parents=`5` &facets=`vendor, option:color`]]

The SeoFilter bridge is written for MODX 2. On MODX 3, use native.

SeoFilter (MODX 2)

Set |alias= as in mFilter2 and &seo=seofilter`` or both. The AJAX response has a seo block: title, h1, description, canonical, aliases. The mscatalyst:seo event on document is there for the SeoFilter bridge or for your own meta tag replacement:

document.addEventListener('mscatalyst:seo', function (e) {
    console.log(e.detail.seo.title, e.detail.seo.canonical);
});

The msCatalystSeoFilter snippet sets the template placeholders.
