+### Modifying Meta Tags
+
+You can override the `MetaComponents()` method on your `SiteTree` sub-classes or make use of the `MetaComponents` extension point to manipulate the underlying data that is rendered by `$MetaTags`. Example (for `Page` class):
+
+```php
+public function MetaComponents()
+{
+ $tags = parent::MetaComponents();
+ // Override the content of the Title tag (needs to be html)
+ if ($this->MetaTitle) {
+ $tags['title']['content'] = $this->obj('MetaTitle')->forTemplate();
+ }
+ // Provide a default Meta Description
+ if (!$tags['description']['attributes']['content']) {
+ // provide raw text as attributes will be escaped later
+ $tags['description']['attributes']['content'] = $this->dbObject('Content')->LimitCharactersToClosestWord(300);
+ }
+ return $tags;
+}
+```
