What is Keyword Suggestion?

Keyword suggestion (related keyword recommendation) is a feature that presents search candidates related to keywords entered by users in search engines. Google Suggest API provides keyword combinations that many users actually search for.

How It Works

This tool sends keywords as queries to the Google Suggest API and retrieves related search suggestions. Furthermore, by using the retrieved keywords as queries again, it recursively collects more related keywords (3 recursive iterations). This builds a comprehensive network of related keywords.

SEO Usage Guide

Keyword Research Basics

Effective SEO requires proper keyword research. Starting from your main keyword, use this tool to collect a wide range of related keywords. Select the optimal keyword set considering search volume, competition level, and conversion rate.

Content Planning Application

Analyze user search intent based on the retrieved keyword list. Creating content corresponding to each keyword maximizes traffic from search engines. Using related keywords in subsections and headings improves page relevance.

Long-Tail Strategy

Focus on long-tail keywords with low competition and high conversion rates. For example, 'diet supplement for women in 40s' is more specific and likely to lead to purchases than just 'diet'.
