SEO: pagination information in title tag TYPO3 >=9

[Zellwerker]

During a SEO optimization, I noticed that the page number is not displayed when paging the newslists. In TYPO3 version 8 this was still possible.

I was able to fix that with the following code.

// GeorgRinger\News\ViewHelpers\Widget\Controller\PaginateController::indexAction()

            // BUG BEGIN: This line no longer works from TYPO3 version 9
            //$GLOBALS['TSFE']->page['title'] .= $titleAddition;
            // BUG END

            // FIX BEGIN: We use the news NewsTitleProvider instead
            $pageTitle = $GLOBALS['TSFE']->page['title'];
            if(!empty($GLOBALS['TSFE']->page['seo_title'])) {
                $pageTitle = $GLOBALS['TSFE']->page['seo_title'];
            }
            \TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance(\GeorgRinger\News\Seo\NewsTitleProvider::class)->setTitle($pageTitle . $titleAddition);
            // FIX END

In \Resources\Private\News\Templates\News\List.html you need to add something like:

<f:if condition="{overwriteDemand.tags}">
	<f:then>
		<f:for each="{tags}" as="tag">
			<f:if condition="{tag.uid} == {overwriteDemand.tags}">
				<f:if condition="{tag.seotitle}">
					<n:titleTag>
						<f:format.htmlentitiesDecode>
							{tag.seotitle}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}
						</f:format.htmlentitiesDecode>
					</n:titleTag>
					<n:metaTag property="og:title" 
						content="{tag.seotitle -> f:format.stripTags()}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}" />
				</f:if>
				<f:if condition="{tag.seodescription}">
					<n:metaTag name="description" 
						content="{tag.seodescription -> f:format.stripTags()}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}" />
					<n:metaTag property="og:description" 
						content="{tag.seodescription -> f:format.stripTags()}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}" />
				</f:if>
			</f:if>
		</f:for>
	</f:then>
	<f:else>
		<f:if condition="{pagination.currentPage} > 1">
			<n:titleTag>
				{pageData.seo_title} {f:if(condition: '{pagination.currentPage} > 1', then: 'page {pagination.currentPage}')}
			</n:titleTag>
			<n:metaTag property="og:title" 
				content="{pageData.seo_title -> f:format.stripTags()}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}" />
			<n:metaTag name="description" 
				content="{pageData.description}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}" />
			<n:metaTag property="og:description" 
				content="{pageData.description -> f:format.stripTags()}{f:if(condition: '{pagination.currentPage} > 1', then: ' page {pagination.currentPage}')}" />
		</f:if>
	</f:else>
</f:if>

here i also set conditions for tags, the same can be used for category pagination
