用 ChatGPT 同 Google Best Practices 生成高效能 SEM 廣告文案
我用 GPT-4 砌咗一個工具,通過分析你嘅 landing page,幾分鐘內生成符合 Google 最佳實踐嘅 RSA 廣告文案——慳返好多鐘同時自動遵循 Google 最新嘅 best practices。
呢篇文章寫於2023年,部分內容可能已經有變化。
做咗 18 年廣告,我可以話你知寫 search ad copy 係嗰啲聽落簡單但實際上食好多時間嘅任務之一。你要將信息塞入嚴格嘅字數限制、命中啱嘅 keywords、跟住 Google 不斷變化嘅 best practices,仲要產出多個變體做 testing。乘以幾十個 campaign 就真係好大工程。
所以我砌咗一個嘢嚟幫手:SEM Ad Copy Expert,一個由 GPT-4 驅動嘅 custom GPT。
我要承認,呢個有部分係為咗解決自己嘅痕癢。返工嗰陣,我睇住 team 花幾個鐘從零開始寫 responsive search ads (RSAs)。我知一定有更好嘅方法。所以我用所有公開嘅 Google search ads best practices 訓練咗一個 custom GPT,確保佢明白 RSA 規格,而家佢幾分鐘就做完以前要幾個鐘嘅嘢。
佢點運作
幾直接:
- 畀佢你嘅 landing page URL、產品資訊、或者幾條關鍵問題嘅答案
- 個工具分析數據並生成有針對性嘅 RSA 廣告文案
- 輸出自動遵循 Google RSA 規格
(如果個工具存取唔到你嘅 landing page,直接 copy and paste 內容入 chatbox——一樣得。)
我覺得佢有用嘅原因
基於我跑 SEM campaign 嘅經驗:
- 真正慳到幾個鐘嘅手動文案寫作時間
- 廣告文案係根據你實際 landing page 內容嘅分析優化嘅,唔係通用 template
- 自動符合 Google 最新嘅 RSA best practices
- 生成多個變體,呢個正正係你做 A/B testing 需要嘅
前後對比例子
為咗更具體,以下係一個虛構 project management 工具嘅廣告文案,應用呢個方法前後可能嘅樣子:
之前(通用,從零寫):
- Headline 1: "Best Project Management Software"
- Headline 2: "Try Our Tool Today"
- Headline 3: "Manage Projects Easily"
- Description: "Our project management software helps teams work better. Sign up for a free trial today."
之後(用 landing page 分析 + Google RSA best practices 生成):
- Headline 1: "Plan, Track & Deliver Projects On Time"
- Headline 2: "Trusted by 10,000+ Teams Worldwide"
- Headline 3: "Free 14-Day Trial — No Credit Card"
- Description: "Reduce project delays by 40% with built-in Gantt charts, real-time dashboards & team collaboration. Start your free trial."
分別在於具體性:真實數字、從 landing page 提取嘅具體功能、清晰嘅 call to action 加上減少摩擦嘅元素(唔使信用卡)、同符合搜索意圖嘅關鍵字豐富 headline。
你可以喺任何地方用嘅 Prompt Template
如果 custom GPT 冇辦法用或者你想用其他 LLM,以下係一個你可以調整嘅 prompt template:
You are an expert SEM copywriter. Generate Google Responsive Search Ad (RSA) copy
for the following product/landing page.
LANDING PAGE CONTENT:
[Paste your landing page text or URL summary here]
TARGET KEYWORDS:
[List your primary and secondary keywords]
REQUIREMENTS:
- Generate 15 headlines (max 30 characters each)
- Generate 4 descriptions (max 90 characters each)
- Include at least 3 headlines with target keywords
- Include at least 2 headlines with numbers or statistics from the landing page
- Include at least 1 headline with a clear call to action
- Descriptions should highlight unique selling points and include a CTA
- Follow Google RSA best practices: vary headline themes, avoid redundancy,
use title case
OUTPUT FORMAT:
List headlines numbered 1-15, then descriptions numbered 1-4.
Flag which headlines contain keywords and which contain CTAs.
「但點解只做 Google RSAs?」
合理嘅問題。三個原因:
- Google 佔 paid search advertising 較大嘅份額,雖然 Microsoft Ads 有佢自己嘅 nuance,但 RSA 格式同 best practices 有好多重疊
- RSAs 係未來嘅格式——佢哋表現優於其他格式,跨 desktop、mobile 同 tablet 都適用
- Shopping Ads 需要 product feeds 而 automation 已經處理咗大部分嘅 heavy lifting
一個小提醒
呢個工具係一個起點,唔係人為判斷嘅替代品。我一定建議檢查同微調輸出。AI 生成嘅文案越嚟越好,但佢仲係唔完全理解你嘅 brand voice、競爭環境、或你特定市場嘅 nuance。將佢當成一個好叻嘅初稿機器 :)
無論你係 search marketing 新手定 PPC 老手,我希望呢個可以幫你慳啲時間。如果有 feedback 或建議話我知——我仲喺迭代緊。
祝好,
Chandler
