Bu platform için özgün, ilgi çekici ve viral potansiyeli yüksek bir içerik oluştur.
|
||||
|
||||
KURALLAR:
|
||||
📈 SEO OPTİMİZASYONU (ZORUNLU):
|
||||
- Bu konuyu Google'da, YouTube'da veya sosyal medyada arayan biri hangi kelimeleri kullanır? O kelimeleri belirle ve içeriğe yerleştir.
|
||||
- İLK 2 CÜMLEDE arama hacmi en yüksek anahtar kelimeleri MUTLAKA kullan.
|
||||
- Hook/giriş cümlesi birincil anahtar kelimeyi içersin.
|
||||
- Anahtar kelimeleri doğal bir akış içinde kullan, zoraki tekrar yapma.
|
||||
- Konu ile ilgili en çok aranan terimleri, teknik terimleri ve marka/ürün adlarını (haberin konusu olan markaları — kaynak değil) ön plana çıkar.
|
||||
|
||||
KRİTİK KURALLAR:
|
||||
1. Karakter limitine uy
|
||||
2. Platformun tonuna uygun yaz
|
||||
3. Hook (dikkat çeken giriş) ile başla
|
||||
4. CTA ile bitir (yukarıdaki CTA talimatına göre)
|
||||
5. Emoji kullan ama aşırıya kaçma
|
||||
6. ${language === 'tr' ? 'Türkçe' : 'İngilizce'} yaz
|
||||
7. ASLA resim URL'i, medya linki veya [görsel] gibi yer tutucular ekleme
|
||||
8. Görsel betimlemeleri metnin içine YAZMA
|
||||
9. İçerik %100 özgün olmalı - asla kaynak kopyası yapma
|
||||
10. Kaynak linklerini, URL'leri veya atıfları ASLA ekleme
|
||||
11. Mevcut içeriklerden alıntı yapma, tamamen yeni ve orijinal yaz
|
||||
12. Bilgiyi kendi cümlelerinle ifade et, paraphrase bile yapma
|
||||
13. Araştırma kaynaklarının isimlerini (web siteleri, haber siteleri, markalar, gazeteler) ASLA metinde kullanma veya referans verme
|
||||
14. "...göre", "...kaynağına göre", "according to" gibi atıf ifadeleri ASLA kullanma
|
||||
7. İçerik %100 özgün olmalı - asla kaynak kopyası yapma
|
||||
8. Bilgiyi kendi cümlelerinle ifade et, paraphrase bile yapma
|
||||
|
||||
⚠️ YAYIN HAZIR İÇERİK (ÇOK ÖNEMLİ):
|
||||
- İçerik doğrudan kopyala-yapıştır ile yayınlanabilir olmalı
|
||||
- "[Buraya Link]", "[Link Ekle]", "[URL]", "[Görsel]", "[Video]" gibi YER TUTUCU İFADELER ASLA kullanma
|
||||
- Resim URL'i, medya linki veya placeholder ASLA ekleme
|
||||
- Görsel betimlemeleri metnin içine YAZMA
|
||||
- "Linke tıklayın", "Bio'daki linke gidin" gibi CTA'lar kullanabilirsin ama asla köşeli parantez içinde placeholder koyma
|
||||
- Eğer bir link veya URL bilmiyorsan, o kısmı tamamen atla — placeholder bırakma
|
||||
- İçerikte doldurulması gereken boşluk OLMAMALI
|
||||
|
||||
⛔ KAYNAK YASAĞI (EN ÖNEMLİ KURAL):
|
||||
- Hiçbir haber sitesi, web sitesi, gazete, ajans, blog veya medya kuruluşu adını ASLA yazma
|
||||
- "Tamindir", "Webtekno", "DonanımHaber", "ShiftDelete", "TechCrunch", "BBC", "CNN", "Reuters", "Forbes", "Bloomberg" gibi site/kaynak adlarını ASLA kullanma
|
||||
- "...haberlere göre", "...raporuna göre", "...kaynağına göre", "...sitesinde yer alan", "...çıkan haberlere göre", "according to", "...tarafından yapılan" gibi ATıF İFADELERİ ASLA kullanma
|
||||
- Haberin nereden alındığını BELİRTME, doğrudan bilgiyi kendi cümlelerinle anlat
|
||||
- İçerikte kaynak gösterme, referans verme veya atıf yapma YOK

|

const controller = new AbortController();
|

const timeoutId = setTimeout(() => controller.abort(), timeout);
|
||||
|
||||
<h2>Introduction</h2>
|
||||
<p>Content creation has evolved significantly over the past year. In this comprehensive guide, we'll explore the most effective strategies for creating engaging content.</p>
|
||||
const response = await fetch(url, {
|
||||
headers: {
|
||||
'User-Agent': userAgent,
|
||||
'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
|
||||
'Accept-Language': 'tr-TR,tr;q=0.9,en-US;q=0.8,en;q=0.7',
|
||||
'Accept-Encoding': 'identity',
|
||||
},
|
||||
signal: controller.signal,
|
||||
redirect: 'follow',
|
||||
});
|
||||
|
||||
<h2>1. Focus on Value First</h2>
|
||||
<p>The most successful content creators prioritize providing value to their audience. According to a recent study, 78% of consumers prefer brands that create custom content.</p>
|
||||
clearTimeout(timeoutId);
|
||||
|
||||
<h2>2. Embrace Short-Form Video</h2>
|
||||
<p>Short-form video continues to dominate. TikTok and Instagram Reels have shown that 15-60 second videos can generate massive engagement.</p>
|
||||
if (!response.ok) {
|
||||
this.logger.warn(`HTTP ${response.status} for ${url}`);
|
||||
return null;
|
||||
}

||||

||||

|
||||
const contentType = response.headers.get('content-type') || '';
|
||||
if (!contentType.includes('text/html') && !contentType.includes('application/xhtml')) {
|
||||
this.logger.warn(`Non-HTML content type: ${contentType} for ${url}`);
|
||||
return null;
|
||||
}
|
||||
|
||||
<h2>3. Use AI Wisely</h2>
|
||||
<p>AI tools like ChatGPT and Claude can help with ideation and drafting, but human creativity remains essential for authentic content.</p>
|
||||
const html = await response.text();
|
||||
|
||||
<h3>Key Statistics</h3>
|
||||
<ul>
|
||||
<li>85% of marketers use content marketing</li>
|
||||
<li>Video content generates 1200% more shares</li>
|
||||
<li>Long-form content gets 77% more backlinks</li>
|
||||
</ul>
|
||||
if (!html || html.length < 100) {
|
||||
this.logger.warn(`Empty or very short response from ${url}`);
|
||||
return null;
|
||||
}
|
||||
|
||||
<h2>Conclusion</h2>
|
||||
<p>Success in content creation requires a balance of strategy, creativity, and consistency. Start implementing these strategies today!</p>
