Detailed Insights

  1. Keyword Surfer

    Keyword Surfer from will provide you with search volumes for queries in SERPs (search engine results pages) as well as other keyword data. It’ll also provide estimated traffic and the number of words for all the results in a SERP.
  2. Ayima Redirect Path

    The Redirect Path plugin will show you the path a URL took before arriving at its destination. Is the URL live (200 status code), was it redirected (3xx) status code), or is it broken (4xx status code)?

    This can help you to diagnose pages on a URL-by-URL basis. Here are some explanations of the main status codes you will find:

    – 200 OK: This status code indicates that the request was successful, and the server has returned the requested content.
    – 301 Moved Permanently: This code is used for permanent URL redirection. It indicates that the requested resource has been moved to a new location permanently.
    – 302 Found: This status code indicates a temporary URL redirection. It tells the client to temporarily use a different URL for the requested resource.
    – 307 Temporary Redirect: redirect status response code indicates that the resource requested has temporarily moved to the URL given by the location headers.
    – 308 Permanent Redirect: redirect status response code indicates that the resource requested has definitively moved to the URL given by the location headers.
    – 400 Bad Request: This status code indicates that the server could not understand the request due to invalid syntax or missing parameters.
    – 401 Unauthorized: It means that the request requires user authentication. The user needs to provide valid credentials (such as username and password) to access the requested resource.
    – 403 Forbidden: This code indicates that the server understands the request, but the client does not have sufficient permissions to access the requested resource.
    – 404 Not Found: This is one of the most well-known status codes. It indicates that the requested resource could not be found on the server.
    – 500 Internal Server Error: This status code indicates that an unexpected error occurred on the server, preventing it from fulfilling the request.
    – 503 Service Unavailable: It indicates that the server is temporarily unavailable, often due to maintenance or being overloaded with requests.
  3. Wappalyzer

    It can often be useful to understand the underlying technology that powers a website. On any domain, click the Wappalyzer extension to see:

    – Which CMS it uses? WordPress, Liferay, Webflow, etc.
    – What analytics is used? Google Analytics, for example
    – What server is used? Nginx, Apache, etc.
  4. Robots Exclusion Checker

    The Robots exclusion checker is a great plugin for checking to see if there are any reasons why a given URL you are on could not be indexed. If the little robot icon is anything but green, it means the URL might have issues being indexed:

    – Green = Indexable
    – Yellow = Canonical points to a different URL
    – Red = Not indexable
  5. User Agent Switcher

    Websites can have different behaviors from different user agents that request their pages. Every web request is sent with an HTTP user agent string and those user agents give different responses from the server, depending on which server it is. For example, CDNs like CloudFlare will return a 403 status code (use Ayima Redirect Path to see the status code) if you request their pages with a Googlebot user agent.

    This extension allows you to be able to switch your user agent from within the browser. If you want to understand how a website reacts to different user agents then try this out.
  6. Web Developer Tools

    This extension is handy for a number of browser functions such as:

    – Disabling JS/CSS
    – Clearing the cache
    – Clearing cookies on a domain or for the whole session
    – Form interactions

    If you want to be able to test developer functions on your website with ease then this is the tool for you.
