+# Scrape & Analyze Google Ads with Bright Data API and AI for Email Reports
+
+### 1. Workflow Overview
+
+This workflow automates the process of scraping Google Ads data via the Bright Data API, analyzing the ad content using AI models, and generating structured email reports summarizing key insights. Its primary use case is for marketing analysts or strategists who want to track keyword-triggered Google Ads, understand advertiser messaging strategies, and receive summarized performance reports via email.
+
+The workflow is logically divided into the following blocks:
+
+- **1.1 Input Reception & Keyword Retrieval:** Trigger and fetch list of keywords from Google Sheets.
+- **1.2 Google Ads Scraping:** For each keyword and country code, scrape Google Search results JSON including ads via Bright Data API.
+- **1.3 Ads Filtering & Extraction:** Filter results to ensure ads exist, then extract top and bottom ads arrays.
+- **1.4 AI Analysis of Ads:** Use multiple AI language models to analyze ads for value propositions, messaging style, and extensions.
+- **1.5 Site Link Extensions Analysis:** Extract and categorize site link extensions from ads.
+- **1.6 Keyword-to-Ad Mapping:** Map keywords to ads and analyze advertiser reuse and messaging differences.
+- **1.7 Report Generation & Emailing:** Combine AI insights, generate an HTML report, and send it via Gmail.
+
+---
+
+### 2. Block-by-Block Analysis

+  - **filter ads**  
+    - Type: Filter  
+    - Role: Checks if `top_ads` array from the JSON response has at least one element to proceed.  
+    - Edge cases: No ads found causing filter to skip.  
+  - **ads found**  
+    - Type: Set  
+    - Role: Extracts `top_ads` and `bottom_ads` arrays from the response JSON for downstream processing.  
+  - **No Operation, do nothing1**
