Complete Workflow Setup#

Step 1: Content Ideation System#

1
// Automated content idea generation
2
const generateContentIdeas = async () => {
3
  // Fetch trending topics
4
  const trends = await $node['Google Trends'].getTrending({
5
    category: 'technology',
6
    geo: 'US',
7
    timeRange: 'now 1-d'
8
  });
9

10
  // Analyze competitor content
11
  const competitorPosts = await $node['RSS Feed'].fetch({
12
    urls: [
13
      'https://competitor1.com/feed',
14
      'https://competitor2.com/feed'
15
    ],
16
    limit: 10
17
  });
18

19
  // Generate unique angles using AI
20
  const prompt = `
21
Based on these trending topics: ${trends.join(', ')}
22
And competitor posts: ${competitorPosts.map(p => p.title).join(', ')}
23

24
Generate 5 unique content ideas that:
25
1. Haven't been covered extensively
26
2. Provide practical value
27
3. Are SEO-friendly
28
4. Include long-tail keywords
29
  `;
30

31
  const ideas = await $node['OpenAI'].completions.create({
32
    model: "gpt-4",
33
    messages: [{ role: "user", content: prompt }]
34
  });
35

36
  return JSON.parse(ideas.choices[0].message.content);
37
};

Step 2: AI Content Generation#

1
// Generate full article with SEO optimization
2
const generateArticle = async (topic, keywords, wordCount = 1500) => {
3
  const articleStructure = {
4
    title: '',
5
    metaDescription: '',
6
    introduction: '',
7
    sections: [],
8
    conclusion: '',
9
    tags: [],
10
    categories: []
11
  };
12

13
  // Generate engaging title
14
  const titlePrompt = `
15
Create an SEO-optimized title for an article about: ${topic}
16
Include keyword: ${keywords[0]}
17
Maximum 60 characters
18
Make it engaging and clickable
19
  `;
20

21
  articleStructure.title = await generateWithAI(titlePrompt);
22

23
  // Generate comprehensive content
24
  const contentPrompt = `
25
Write a ${wordCount}-word article about: ${topic}
26
Title: ${articleStructure.title}
27

28
Structure:
29
1. Introduction (150 words) - Hook the reader
30
2. Main sections (${Math.floor(wordCount/300)} sections)
31
3. Practical examples
32
4. Conclusion with CTA
33

34
SEO Requirements:
35
- Use keywords naturally: ${keywords.join(', ')}
36
- Include headers (H2, H3)
37
- Add internal linking opportunities [LINK]
38
- Format for featured snippets
39

40
Style: Professional, engaging, actionable
41
  `;

    max_tokens: 3000
47
  });
48

49

Step 3: Automated SEO Optimization#

1
// SEO analysis and optimization
2
const optimizeForSEO = async (article) => {
3
  const seoScore = {
4
    readability: 0,
5

32

33
  // Generate meta description
34

37
// Generate Open Graph images
38
