I. Core Ideas of Keyword Research (2025 Edition)

Starting from "user intent"

Google's algorithm is increasingly focusing on search intent.
You need to first determine which intent type your keywords belong to:

Informational : Users are searching for information, such as "What is AI drawing?"
Navigational : Users want to access a specific website, such as "Canva Login".
Transactional : Users are ready to make a purchase, such as "best AI image tool price".

Tip : By searching for the keyword and observing the types of results that appear on the SERP (blogs, product pages, videos, etc.), you can infer your search intent.

II. Strategies for Finding High-Potential Keywords

1. Start with "low-competition long-tail keywords"

In 2025, long-tail keywords will remain the best entry point for small and medium-sized websites to quickly acquire traffic.

Example:
❌ "SEO Tools" → High search volume but extremely competitive
✅ "Best Free SEO Tools of 2025" → Moderate search volume, higher conversion rate

Recommended tools:

Ahrefs / Semrush → View Keyword Difficulty (KD) and Traffic Potential
Google Keyword Planner → Get Real Search Volume Trends
LowFruits.io → Find long-tail keywords with low competition and weak SERPs

2. Utilize "Related Searches" and "People Also Ask"

Discover new topics in the "People Also Ask" (PAA) section at the bottom of Google search results.
You can quickly obtain question-related keywords using AlsoAsked.com or AnswerThePublic.

3. Use AI tools for keyword expansion

By 2025, many AI tools will be able to combine semantic understanding to generate more natural keyword clusters.

Recommended tools :
- ChatGPT + Ahrefs API / Semrush data
- SurferSEO / Frase.io / NeuronWriter : Analyze SERP content, generate content outlines, and cluster keywords.
- KeywordInsights.ai : AI-powered clustering of related keywords, automatically grouping them into article topics.
