Introduction

What does it do?

The goal of the core extension "seo" is to make sure basic technical Search Engine Optimization (SEO) is done right out of the box. Specific fields for SEO purposes are added, as well as the rendering of HTML meta tags in the frontend.

There are several things you can do to optimize your site for search engines. Some tasks are only solvable with good human writers, others are technical tasks, which just need to be implemented.

The goal of the extension seo is to help you with the following parts of your seo journey.

  • Give editors all the fields needed to set the necessary meta tags
  • Provide the rendering of meta tags in the frontend for SEO related information, to avoid reimplementing it again and again
  • Provide stable APIs for developers to give them the chance to change the behaviour when needed in edge cases

This manual will not cover all the developer information, as these are covered in the TYPO3 API documentation.

Hreflang Tags

"hreflang" tags are added automatically for multi language websites based on the one-tree principle. The links are based on the Site configuration and depending on translations of a page.

The x-default href is the link of the current page in the default language.

The value of hreflang is set for each language in the Sites module (see Adding Languages)

Canonical Tags

TYPO3 provides built-in support for the canonical tag.

If the core extension "seo" is installed, it will automatically add the canonical link to the page.

The canonical link is basically the same absolute link as the link to the current hreflang and is meant to indicate where the original source of the content is. It is a tool to prevent duplicate content penalties.

In the page properties, the canonical link can be overwritten per language. The link wizard offers all possibilities including external links and link handler configurations.

If no canonical link is given manually, TYPO3 will generate a canonicalized URL to the current page in the current language.

XML Sitemap

See XML sitemap for the documentation how to configure your XML sitemaps.
