# Audit issue types

> Every check a site audit runs, what each means, and how to fix it.

Source: https://docs.indexzero.site/reference/audit-issue-types



A site audit checks every crawled page against the <AuditIssueCount /> issue types below, grouped by severity. The `issueType` argument of `get_audit_issues` accepts the id in the second line of each row. The explanations and fixes are the same text the dashboard shows.

## Critical [#critical]

<AuditIssuesTable severity="critical" />

## Warnings [#warnings]

<AuditIssuesTable severity="warning" />

## Informational [#informational]

<AuditIssuesTable severity="info" />

## Thresholds used [#thresholds-used]

* **Slow response** means the HTML took more than 1.5 seconds.
* **Deep page** means five or more clicks from the homepage.
* **Title length** flags under about 10 characters or over about 60.
* **Meta description length** flags under about 70 characters or over about 160.
* **Blocked page** covers a bot challenge, a 401, 403, or 429, or a 503 whose body is a challenge page. The crawler identifies as `IndexZero-Audit/1.0`; allowlisting that user agent is the fix.
