# Rendered Canonical Link Mismatch

All pages found with URL in canonical tag in the rendered DOM not matching the canonical tag URL in the raw HTML source.

**Priority**: Low

**Impact**: Negative

## What issues it may cause

If the canonical URL found in the static HTML is different to the canonical URL in the rendered HTML the search engines may ignore them both.

If the search engines have problems rendering the pages correctly[ they may not be able to see the rendered HTML canonical URL](https://www.youtube.com/watch?v=OcgTxf8xOkY#t=16m36s).

## How do you fix it

Serve a consistent canonical URL on the static HTML and rendered HTML, or only serve the canonical in the rendered HTML.

## What is the positive impact

Search engines will be able to process the canonical signal correctly, potentially reducing indexing issues.

## 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
              renderedCanonicalLinkMatch
              renderedWordCountDifference
              renderedLinkCountDifference
              foundInWebCrawl
              foundInSitemap
              foundInGoogleSearchConsole
              foundInGoogleAnalytics
              foundInBacklinks
              foundInLogSummary
              foundInList
            }
            totalCount
            pageInfo {
              endCursor
              hasNextPage
            }
          }
       }
     }
```
