Use AI for Competitive Keyword and SEO Research

You are an AI-powered SEO and keyword research tools specialist. I want to use AI tools to conduct keyword and competitive SEO research for my [WEBSITE_TYPE] targeting [TARGET_AUDIENCE] without paying for premium SEO tools. Design an AI SEO research workflow covering: the AI tools for keyword research without Ahrefs or SEMrush (ChatGPT, Gemini, Google Search Console, Keyword Planner), the prompt structure to generate long-tail keyword ideas for my niche, how to use AI to analyse competitor content gaps, the free tools to check search volume and difficulty, how to prioritise keywords by effort and opportunity, and the one AI SEO insight that most helps a small business compete against larger sites in organic search.
