# SEO # General # How do I add SEO Metadata to a page? You can use the `\Aero\Marketing\Facades\SearchOptimization` facade to add SEO Metadata to a page. See below an example of how we do it for `\Aero\Store\Http\Responses\Homepage` & `Aero\Store\Http\Responses\InformationPage` by adding the `Aero\Store\Http\Responses\Steps\Page\AttachMetaData` step: ```php class AttachMetaData { public function handle(\Aero\Responses\ResponseBuilder $builder, \Closure $next) { /** @var $page \Aero\Content\Models\Page */ $page = $builder->page; if (! $page->key) { \Aero\Marketing\Facades\SearchOptimization::setTitle($page->name); } if ($page->seo) { \Aero\Marketing\Facades\SearchOptimization::setCanonical($page->getCanonical()); if (! empty($page->seo->page_title)) { \Aero\Marketing\Facades\SearchOptimization::setTitle($page->seo->page_title, false); } if ($page->seo->noindex) { \Aero\Marketing\Facades\SearchOptimization::setNoIndex(); } if ($page->seo->nofollow) { \Aero\Marketing\Facades\SearchOptimization::setNoFollow(); } } \Aero\Marketing\Facades\SearchOptimization::setDescription($page->getMetaDescription()); \Aero\Marketing\Facades\OpenGraph::withPage($page); return $next($builder); } } ``` --- ### Methods
