Scrape articles by length?

Do you know of any way to find articles of a certain number of words?

Right now if I search on Google "what's the best iPhone" I need to click each result and see its size.

Ummm, try this.

1. Scrape Google/Yahoo/Bing, etc. with ScrapeBox, or use a Chrome/Firefox extension for that
2. Upload the URLs in Screaming Frog (List Mode); set the level depth to 1, and hit start.
3. Check the Word Count tab, in the Internal/All section.

This is what I would do. Hope it helped.
