Okay, the user wants me to write an SEO article about “free ethereum airdrop on zksync”. Let me start by understanding the keyword. They need around 900 words with H2s, lists, and a FAQ. First, I should outline the structure.

The main H2s could be an introduction, what the airdrop is, how to participate, benefits, common mistakes, FAQs, and a conclusion. That makes sense. I need to make sure each section is informative and includes the keyword naturally.
For the introduction, I should explain what an Ethereum airdrop on ZKSync is. Maybe mention that ZKSync is a Layer 2 scaling solution, which helps with lower fees. Then, in the next section, define the airdrop and why it’s happening. Highlight the benefits like supporting the ecosystem and rewarding users.
How to participate section needs a step-by-step list. Users will want clear instructions. I should include steps like connecting a wallet, ensuring ETH is on ZKSync, interacting with dApps, and claiming the airdrop. Also, mention possible requirements like holding tokens or completing tasks.
Benefits of participating: lower fees, faster transactions, supporting innovation. Maybe a bullet list here. Common mistakes could be not bridging ETH correctly, missing deadlines, ignoring security. Another bullet list.
FAQs are important. Common questions like eligibility, how long it takes, risks involved, if it’s free, and how to check eligibility. Need to answer these concisely.
I should also include keywords naturally throughout the content. Maybe use variations like “ZKSync airdrop”, “Ethereum airdrop”, “free crypto rewards”. Avoid keyword stuffing but ensure SEO optimization.
Check for readability. Use short paragraphs, subheadings, and lists. Make sure the tone is friendly and encouraging. Also, include a call to action in the conclusion, like advising readers to participate and stay updated.
Wait, the user specified to return STRICT JSON with title and content. So I need to structure the entire article within those tags. No markdown, just plain text with H2s as headings. Let me make sure the content flows well and covers all required elements without any markdown formatting.
Also, verify that the word count is around 900. Let me estimate each section’s length. Intro: 100 words, What is: 150, How to participate: 200, Benefits: 100, Common mistakes: 100, FAQ: 200, Conclusion: 100. That adds up to around 950. Maybe adjust to hit closer to 900.
Double-check for any inaccuracies. For example, confirming that ZKSync is indeed a Layer 2 solution and that airdrops are common there. Also, ensure that the steps are accurate, like bridging ETH via the official bridge.
Avoid any promotional language. Keep it informative and neutral. Mention that users should do their own research and be cautious of scams. That’s important for credibility and user safety.
Alright, time to put it all together in the required JSON format without any markdown. Make sure the title is catchy and includes the keyword. The content should have all the sections with H2s, lists, and FAQs as specified. Let me review once more to ensure everything meets the user’s requirements.
