Lower Tab

Analysis of the most used Screaming Frog’s Lower Tabs for capillary and asaurient monitoring of significant data during Seo Audits.


Browsing this tab allows you to isolate all the images on a page and in case you select the url of an image to get the preview.

The data you can get are:

  • From: shows the selected url.
  • To: the reference of the images found in the html page.
  • Alt Text: shows the text of the “alt” attribute if present in the code.


By consulting this tab, it is possible to isolate any pages with duplicate or very similar content to the selected url.

This tab shows which URLs are similar, if any, and defines the degree of similarity with a percentage scale.

Once you have collected the data, if you click on a “Near Duplicate Address” in the tab you can see a comparison between the pages with their differences highlighted.

The SERP Snippet tab is a useful ally for seeing how the URL snippet is displayed in Google search results. Through this tab, it is possible to optimize the snippet by avoiding truncations in Search Engine results by having a proper view on both desktop and mobile side. The truncation point (where Google shows (…) and cuts off words) is calculated based on the width of pixels and characters.

On the left side of the tab is a preview of the snippet, and on the right side is an overview table. The Search Engine has never officially defined the size in pixels or the maximum number of characters that can be used without falling into truncation, so these thresholds were defined by the Seo Spider based on various SERP studies.

The SERP snippet emulator uses the desktop by default.

Config > Spider > Preferences

You can change the type of devices to be simulated to see how the snippets can appear in desktop, tablet, or mobile switchand from the drop-down menu.

Very convenient is the interface that allows you to edit page titles and descriptions directly in the window by saving the changes automatically (Database Storage), unless you click on the “restore title and description” button that restores it to its original state. This feature allows you to refine your snippets and export the document (‘Reports > SERP Summary’) to send to a client or development team to integrate your meta tags on the website.

Rendered Page

The tab allows you to see the rendered page that the SEO Spider has scanned in JavaScript mode.

This feature is enabled by default when using the JavaScript rendering feature, and works in conjunction with the configured user-agent, AJAX timeout, and viewport size.

This feature is set to “blocked resources” by default, but this can also be changed to show “all resources” used by the page.

View Source

The “View Source” tab allows you to collect and compare data from the static HTML and rendered HTML of a selected page from the top window; this functionality is contingent on enabling “Store HTML” or “Store Rendered HTML.”

Configuration > Spider > Extraction > Store/ HTML / Store HTML Rendered

The tab provides an internal search filter to make it easy to locate elements in the code.

The left screen allows you to view the original HTML before the JavaScript comes into play, in the same way as a right click on “view source” in a browser. This is a great tool for debugging, or for comparison with rendered HTML.

The left preview allows you to save the rendered HTML of each URL scanned by the SEO Spider to disk and view the DOM as if it were “Inspect Element” (in Chrome in DevTools), after the JavaScript has been processed.

HTTP Headers

This tab collects data related to HTTP Header responses.

Configuration > Spider > Extraction > HTTP Header

On the left side of the tab you can see the HTTP request headers while on the right side you can see the HTTP response headers.

Columns available to you include:

  • Header Name: the name of the response header from the server.
  • Header Value: The value of the response header from the server.

Once extracted, the HTTP headers are added in columns in the Internal tab, where they can be queried along with the crawl data.

The HTTP Headers Summary can be exported analytically via Bulk Export > Web > All HTTP Headers” or in aggregate via “Reports > HTTP Headers > HTTP Headers Summary.”


To populate this Tab remember to enable the Seo Spider to scan and store Cookies. Once you select one or more URLs from the upper window you will find the details in the Cookies Tab of the lower screen.

Configuration > Spider > Extract> Cookie

You can also use the “Rendering JavaScript” scan mode to get an accurate view of cookies that have been loaded on the page using JavaScript or pixel image tags.

Cookie tab columns include:

  • Cookie Type: identifies where the cookie was discovered( ‘HTTP’, ‘On-Page’ etc).
  • Cookie Name: collects the name of the cookie.
  • Cookie Value: defines the value of the cookie.
  • Domain: shows the domain that issued the first- or third-party cookie.
  • Expiration Time: indicates the expiration time of the cookie.
  • Secure: displays the details of the security attribute of the cookie.
  • HttpOnly: shows the details of the HttpOnly attribute of the cookie.
  • Address: displays the URL on which the cookie was found.

Bulk Export > Web > All Cookies

Please note: By default the Seo Spider when you choose to store cookies disables automatic exclusion for Google Analytics tracking tags to ensure an accurate view of all cookies issued including analytics cookies.

Structured Data

As you know, structured data are items highly regarded by the Search Engine, and the “Structured Data” tab comes back very useful for optimizing them and avoiding errors or validation warnings. The data available in the bottom window tab are provided based on the URL selected in the top window, provided the scan has been configured to extract them.

Configuration > Spider > Extraction > JSON-LD/Microdata/RDFa & Schema.org Validation/Google Validation

On the left side you can see property values with associated icons in the case of errors and/or warnings; just click on resources with errors to get specific validation details in the right window.

  • Validation Type: identifies the structured data field with its validation problem (Item, Person, Product, etc.).
  • Issue Severity: shows whether the entity should be considered an error or a warning according to Schema.org guidelines.
  • Issue: details about the specific problem encountered are displayed.

Spelling and Grammar

This tab, once the relevant option is enabled from the “config” menu, contains details on any spelling and grammar problems for each URL selected in the upper window of the Seo Spider.

The “Tab Spelling & Grammar Details” tab displays the list of errors and whether they are spelling or grammatical errors providing suggestions and advice to correct the problem.
The right screen allows preview of the page text and identified errors.

By default the vocabulary set is English but you can customize the analysis with the vocabulary of your language.
