SearchDiggity: Avoid Bot Detection Issues by Leveraging Google, Bing, and Shodan APIs
by Chris Davis, on Aug 29, 2014 6:24:19 AM
Are you plagued by Google bot detection? Are your SearchDiggity scans almost immediately pausing, promising you that they’ll be “Auto-resuming in 15 minutes.”? Do you want to avoid the frustration resulting from the Google-Bot-Detection-Blues? Then you have come to the right place. We’ll show you how you can leverage the official APIs for Google, Bing, and SHODAN within SearchDiggity, so that you can avoid having your scans blocked when performing Google Hacking assessments.
Blocked by Bot Detection
Many of you have written me, asking for help because SearchDiggity was randomly “pausing” and you didn’t know why. You filled in your target domain names, you checked the boxes on the left, you clicked SCAN … and shortly thereafter you received an error message that looked something like this:
Scanning paused [8/28/2014 8:55:40 AM]. Google has detected bot activity.
Auto-resuming in 15 minutes.
Here’s a closer look:
What does “Scanning paused…Auto-resuming in 15 minutes” mean?
Google has detected that you are running a program (e.g., SearchDiggity) to perform automated Google searches, as opposed to a human browsing www.google.com manually typing in search queries. When this happens, they block you for a short period of time (previously 14 minutes – hence the auto-resume time of 15 minutes).
Alternatively, Google lets you avoid waiting by presenting a CAPTCHA – giving you the opportunity to prove that you are, in fact, a human being… and not an automated computer program. If you could see through the eyes of SearchDiggity as it interacts with Google, you would see something like this:

This causes SearchDiggity scans to pause for 15 minutes. There are a number of ways you can configure SearchDiggity to avoid this type of Google bot detection, such as altering scan speed or leveraging open web proxies to spread your queries across. However, this isn’t exactly easy for a novice user who simply wants to type in search criteria and click SCAN.

Avoid the Hassle – Use the APIs
To completely avoid the hassle of constantly having your scans paused due to bot detection, you can configure SearchDiggity to use the official APIs provided by Google, Bing, and SHODAN instead of scraping.
Quick Overview of APIs
The below figure gives a high-level overview of the Google and Bing APIs used by SearchDiggity:
Quick Links – Signing up for APIs
To use the official APIs, you’ll need to sign up and get yourself an API key for each service, i.e., Google, Bing, and SHODAN. The following links will take you where you need to go to sign up:
- Google API:
- Google - API Console
- Google - Custom Search JSON/Atom API
- Google - Custom Search JSON/Atom API - Pricing
- Google Custom Search ID:

- SHODAN API:
Drawbacks of Using the API
There’s a few downsides to this approach:
- Cost– Using the APIs cost money, while scraping is free. However, the cost is extremely small and in my opinion worth it to avoid the aforementioned hassles.
- Limited Results– the APIs limit the total number of results per query you can get when compared to the normal web browser interface. Also, it seems that the result sets themselves are smaller in total when comparing the API results to the web browser results for Google for instance.
SearchDiggity – Filling in the API Keys
Most tools within SearchDiggity are automatically set to use scraping for both Google and Bing searches. If you wish to turn this off and instead query Google and Bing through their APIs, it’s simple. Within the individual settings space for each tool, check the Disable Scraper check box to reveal the input fields for the API to use instead.
For GoogleDiggity, fill in the API key as shown below:
For BingDiggity, fill in the API key as shown below:
For ShodanDiggity, fill in the API key as shown below:
