AMP

AMP

The AMP tab includes Accelerated Mobile Pages (AMP) discovered during a crawl. These are identified via the HTML AMP Tag, and rel=”amphtml” inlinks. The tab includes filters for common SEO issues and validation errors using the AMP Validator.

Both ‘Store‘ and ‘Crawl‘ AMP options need to be enabled (under ‘Config > Spider’) for this tab and respective filters to be populated.

Columns

This tab includes the following columns.

• Address – The URL crawled.
• Occurrences – The number of canonicals found (via both link element and HTTP).
• Indexability – Whether the URL is indexable or Non-Indexable.
• Indexability Status – The reason why a URL is Non-Indexable. For example, if it’s canonicalised to another URL.
• Title 1 – The (first) page title.
• Title 1 Length – The character length of the page title.
• Title 1 Pixel Width – The pixel width of the page title.
• h1 – 1 – The first h1 (heading) on the page.
• h1 – Len-1 – The character length of the h1.
• Size – Size is in bytes, divide by 1024 to convert to kilobytes. The value is set from the Content-Length header if provided, if not it’s set to zero. For HTML pages this is updated to the size of the (uncompressed) HTML in bytes.
• Word Count – This is all ‘words’ inside the body tag. This does not include HTML markup. Our figures may not be exactly what doing this manually would find, as the parser performs certain fix-ups on invalid html. Your rendering settings also affect what HTML is considered. Our definition of a word is taking the text and splitting it by spaces. No consideration is given to visibility of content (such as text inside a div set to hidden).
• Text Ratio – Number of non-HTML characters found in the HTML body tag on a page (the text), divided by the total number of characters the HTML page is made up of, and displayed as a percentage.
• Crawl Depth – Depth of the page from the start page (number of ‘clicks’ away from the start page). Please note, redirects are counted as a level currently in our page depth calculations.
• Response Time – Time in seconds to download the URI. More detailed information in can be found in our FAQ.

SEO Related Filters

This tab includes the following SEO related filters.

• Non-200 Response – The AMP URLs do not respond with a 200 ‘OK’ status code. These will include URLs blocked by robots.txt, no responses, redirects, client and server errors.
• Missing Non-AMP Return Link – The canonical non-AMP version of the URL, does not contain a rel=”amphtml” URL back to the AMP URL. This could simply be missing from the non-AMP version, or there might be a configuration issue with the AMP canonical.
• Missing Canonical to Non-AMP – The AMP URLs canonical does not go to a non-AMP version, but to another AMP URL.
• Non-Indexable Canonical – The AMP canonical URL is a non-indexable page. Generally the desktop equivalent should be an indexable page.
• Indexable – The AMP URL is indexable. AMP URLs with a desktop equivalent should be non-indexable (as they should have a canonical to the desktop equivalent). Standalone AMP URLs (without an equivalent) should be indexable.
• Non-Indexable – The AMP URL is non-indexable. This is usually because they are correctly canonicalised to the desktop equivalent.

The following filters help identify common issues relating to AMP specifications. The SEO Spider uses the official AMP Validator for validation of AMP URLs.
