Section 1: Keyword Research for WordPress On-Page SEO Checklist
Before writing a single word, keyword research must be completed. Without proper keyword selection, even the best-written content will fail to rank.
Tool 1: Google Keyword Planner
Google Keyword Planner is one of the most reliable tools because the data comes directly from Google. Although originally designed for advertisers, SEO professionals use it to understand keyword demand and competition.
Using this tool, you can:
- Discover primary and secondary keywords
- Analyze average monthly search volume
- Identify commercial vs informational intent
- Find location-based keyword opportunities
For a WordPress On-Page SEO Checklist, the main focus should be on low to medium competition keywords with clear search intent. Avoid targeting only high-volume keywords, as they are often dominated by authoritative websites.

When optimizing WordPress content, Ahrefs helps you select keywords that are realistically achievable while still driving meaningful traffic.
Section 2: Search Intent Optimization in WordPress On-Page SEO
Search intent defines why a user searches for a query. Google prioritizes content that best satisfies intent.

| Commercial | Best WordPress SEO plugins |
| Transactional | Buy SEO audit service |
Your WordPress On-Page SEO Checklist content should primarily target informational and commercial intent, depending on your monetization strategy.
Tool 3: Google Search Results (Manual SERP Analysis)
Sometimes, the best tool is Google itself. Analyze the top 10 ranking pages and observe:
- Content format (guides, lists, videos)
- Average content length
- Use of images and tables
- Featured snippets
This helps align your content structure with what Google already prefers.
