Verify Meta Description
Ensure every page has a non-empty meta description tag.
The Problem
Meta descriptions don’t directly affect rankings, but they control your SERP snippet — the text that convinces a human to click. Google rewrites ~70%% of meta descriptions, but having a targeted one still improves CTR. For pSEO, a missing meta description template means thousands of pages with Google-generated snippets that may not match your intent.
The Hard Way
View source, find the <meta name="description"> tag. Multiply by 10,000 pages and you need a crawler.
