3. Ignoring Search Intent

Targeting keywords without understanding user needs:

• Intent Mismatch: Creating content that doesn't satisfy the intent behind target keywords
• Format Mismatch: Using the wrong content format for the query type
• Depth Mismatch: Providing too much or too little information relative to user expectations
• Audience Mismatch: Creating content at the wrong knowledge level for the target audience
• Call-to-Action Mismatch: Pushing conversions when users are in research mode

Best Practice: Analyze the current top-ranking pages for target keywords to understand the intent Google has identified for those queries.

Conclusion: Building Sustainable Search Success

As we look toward 2019, successful SEO requires a balanced approach that:
