Non-200 Mobile/AMP

URLs which were found within the mobile/AMP rel alt tag of another page, but which return a non-200 HTTP status code

Priority: High

Impact: Negative

What issues it may cause

URLs which are referenced as a mobile or AMP alternate from another page should return a 200 HTTP status code. Error pages (4xx/5xx) will mean that the mobile alternate page is unable to be indexed. A 3xx status code may still mean the destination URL will be indexed (assuming it has a correct reciprocal link), however will unnecessarily consume crawl budget.

This issue may result in:

  • users on mobile devices landing on pages optimised for desktop devices potentially resulting in a bad user experience
  • drop in rankings and traffic from mobile search

How do you fix it

Use this report to ensure that either your pages are designed for mobile devices e.g. responsive design or have valid mobile alternate pages that return 200 HTTP status code.

You can use tools tools like Mobile Friendly Test to understand if your pages are configured correctly for mobile devices.

What is the positive impact

Having pages that are valid and well optimised for mobile devices results in good user experience and higher rankings in search engine results pages which translates into more visits and conversions.

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:

query GetReportForCrawl($crawlId: ObjectID!, $reportTemplateCode: String!) {
getCrawl(id: $crawlId) {
reportsByCode(
input: {
reportTypeCodes: Basic
reportTemplateCodes: [$reportTemplateCode]
}
) {
rows {
nodes {
