Build an RSS Filter in 10 Minutes (No Coding Required)

The Best RSS Filter Techniques for Relevant Content Only

1. Use keyword inclusion and exclusion

• Include: specify must-have keywords or phrases to only pass items containing them.
• Exclude: add negative keywords to block unwanted topics or sources.

2. Score and threshold filtering

• Assign points for matches (e.g., +2 for title match, +1 for tag match, -3 for exclude words) and deliver items scoring above a set threshold.

3. Filter by metadata

• Use author, tags/categories, source domain, and publication date to accept or reject items.

4. Regex and exact-match rules

• Apply regular expressions for precise pattern matching (URLs, ISBNs, version numbers) and exact-match for phrases to avoid false positives.

5. Language and region filtering

• Detect content language and geo-specific markers; filter out languages or regions you don’t want.

6. Duplicate and near-duplicate suppression

• Hash content or compare titles/snippets to drop reposts, summaries, or syndicated duplicates.

7. Content-length and media type rules

• Filter by word count or presence of images/video to prefer in-depth articles or multimedia posts.

8. Time-window and freshness controls

• Prioritize recent items and ignore older posts or set time-based delivery (e.g., only last 24 hours).

9. Learning-based ranking

• Use a lightweight classifier or simple Bayesian filter trained on liked/disliked items to surface more relevant feeds over time.

10. Human-in-the-loop refinement

• Add quick feedback actions (save, discard, mark as relevant) to iteratively refine rules and training data.

Quick implementation checklist

1. Decide primary signals (keywords, tags, authors).
2. Create inclusion/exclusion lists and regex rules.
3. Implement scoring and a delivery threshold.
4. Add dedupe and freshness rules.
5. Optionally train a simple classifier and collect user feedback.

Example rule set (simple)

• Include if title contains: “privacy”, “research” (+2)
• Include if tag matches: “AI”, “ML” (+1)
• Exclude if body contains: “sponsored”, “advertisement” (-5)
• Reject if published > 7 days old
• Minimum score to deliver: 2

If you want, I can convert this into filters for a specific RSS reader (Feedly, Inoreader, Tiny RSS) or generate regex examples.
