Source Attribution

• If referencing external content, include proper citations or author credits.

• For paid or promotional links, use rel="nofollow", rel="sponsored", or rel="ugc" to prevent search engine crawlers from tracking them, which could otherwise impact rankings.

Avoid Duplicate Links

• Multiple pages linking to the same external URL may trigger algorithmic penalties. Diversify linking strategies where possible.

Duplicate & Plagiarized Content

• Ensure original content—rewrite or remove copied material.

• Auto-generated content (e.g., machine-written articles) must be thoroughly reviewed or removed entirely.

Keyword Optimization

• Limit keyword stuffing (e.g., no more than 3 repetitions per page).

• Prioritize high relevance (e.g., for Yandex, use variations like "俄罗斯搜索引擎", "俄罗斯搜索", or "俄罗斯搜索引擎Yandex").
