Project Overview
LinkCrayon set out to build a next-generation Backlink Suggestion Tool—LinkBot—designed to streamline keyword analysis and URL ranking for modern link-building campaigns. OpenAI’s GPT models are utilized to generate intelligent backlink suggestions, helping improve off-page SEO by identifying high-quality linking opportunities with minimal manual effort.
The system was designed around two core functions: processInputDomain() and handleSelectedKeywords(), enabling a full-cycle SEO process—from keyword discovery to intelligent URL ranking—all within a user-friendly environment.

Project Objectives
- Automate keyword research using AI-driven analysis.
- Identify high-value, niche-relevant SEO keywords for any domain.
- Rank URLs based on selected keywords to support link-building.
- Minimize manual SEO input through intelligent automation.
- Deliver fast, scalable, and accurate SEO insights to LinkCrayon users.
Project Execution
1. processInputDomain() Function
This function initiates the keyword discovery phase. When a user inputs a domain and niche, the function validates the request, initializes a PHP session, and calls the OpenAI GPT-4o-mini model to analyze the domain’s content. The AI responds with a markdown table of the top 10 SEO keywords including metrics such as Search Volume and Difficulty.
The system then:
- Parses the markdown into structured keyword data.
- Checks for an existing project or creates a new one.
- Stores the keywords, domain, niche, and project ID in session.
- Returns a structured JSON response to the frontend.
Error handling is built-in for invalid input, session issues, or API failures.
2. handleSelectedKeywords() Function
Once a user selects their preferred keywords, this function manages keyword association and URL ranking.
Key steps include:
- Validating the selected keywords, project ID, niche, and domain.
- Storing each keyword into the corresponding project using internal functions.
- Fetching relevant URLs based on niche and keyword combinations.
- Sending a request to OpenAI’s GPT-4o model to rank URLs based on contextual relevance.
- Saving the top URLs to the user’s Wishlist.
- Cleaning up session data post-success.
The function ensures that users not only get SEO insights but also a prioritized list of URLs they can target for backlinking.
