# Canonicalized Pages

Pages with URLs that are different to the canonical URL specified in the canonical tag in either the HTML or HTTP header. This excludes mobile or AMPHTML pages with correct reciprocation to a desktop URL.

**Priority**: None

**Impact**: Neutral

## What issues it may cause

If the canonical URLs are incorrectly configured, it could result indexing issues or the canonical tag being ignored.

If pages which should be canonicalized to another URL are not, then these pages may be indexed in place of the preferred URL, or result in authority being diluted between the different URLs resulting in both URLs ranking less effectively.

## How do you fix it

The canonical URLs should be reviewed to ensure they are using the preferred canonical URL format.

The list of canonicalized URLs should be reviewed to ensure that it only includes URLs which are not in the preferred canonical URL format.

## What is the positive impact

<ul>
  <li>
    Correctly configured canonical URLs can help to resolve duplication issues, and ensure that the preferred URLs is
    indexed, and authority signals from all the canonicalized URLs are aggregated to the canonical URL.
  </li>
  <li>
    The canonicalized URLs will be re-crawled by Search Engines less frequently so crawling efficiency may also be
    improved.
  </li>
</ul>

## How to fetch the data for this report template

You will need to run a crawl for report template to generate report. When report has been generated and you have
crawl id you can fetch data for the report using the following query:


```graphql
query GetReportStatForCrawl(
      $crawlId: ObjectID!
      $reportTemplateCode: String!
      $after: String
     ) {
        getReportStat(
          input: {crawlId: $crawlId, reportTemplateCode: $reportTemplateCode}
        ) {
          crawlUrls(after: $after, reportType: Basic) {
            nodes {
              pageTitle
              url
              canonicalUrl
              foundAtUrl
              deeprank
              level
              isSelfCanonical
              canonicalizedPage
              foundInGoogleAnalytics
              foundInGoogleSearchConsole
              foundInBacklinks
              foundInList
              foundInLogSummary
              foundInWebCrawl
              foundInSitemap
            }
            totalCount
            pageInfo {
              endCursor
              hasNextPage
            }
          }
       }
     }
```

**Variables:**
```json
{"crawlId":"TjAwNUNyYXdsNDAwMA","reportTemplateCode":"canonicalized_pages"}
