Best for clean, simple, and efficient content. - Highly readable with short sentences and plain English. - Practical and approachable tone, avoids rambling. - Downside: May underuse keywords, which can affect SEO if not prompted carefully[^1](https://trackerly.ai/blog/best-llm-for-blog-writing). **Llama 3 (Meta)** -

**Most LLMs struggle with deep semantic coverage and proper use of LSI (latent semantic indexing) terms.** Even top models like GPT-4 and Claude 3.5 may not fully optimize for Google’s ranking requirements unless specifically prompted and reviewed[^3](https://www.pageoptimizer.pro/blog/we-analyzed-9-major-llms-heres-which-llm-is-best-for-seo). - **PageOptimizer Pro (POP AI)** scored highest for SEO keyword inclusion, but is a specialized tool rather than a general-purpose LLM[^3](https://www.pageoptimizer.pro/blog/we-analyzed-9-major-llms-heres-which-llm-is-best-for-seo). ## Cost and Context Window Model Context Window Input/Output Cost (per 1M tokens) Notes Claude-3-Haiku 200K tokens $0.25/$1.25 Budget-friendly[^5](https://trackerly.ai/blog/best-llm-for-blog-writing) Gemini-1.5-Pro 2M tokens $1.25/$5 Long-form, creative[^5](https://trackerly.ai/blog/best-llm-for-blog-writing) GPT-4O-Mini 128K tokens $0.15/$0.6 Value-focused[^5](https://trackerly.ai/blog/best-llm-for-blog-writing) Llama 3.3 70B 128K tokens $0.72/$0.72 Open-source[^4](https://trackerly.ai/blog/best-llm-for-blog-writing) Command-R 128K tokens $0.15/$0.6 Balanced[^5](https://trackerly.ai/blog/best-llm-for-blog-writing) ## Recommendations by Use Case -
