Why would I want to block Meltwater?

There are two main reasons to block Meltwater: 1. **Competitive intelligence**: Meltwater users (your competitors) can analyse your backlink profile, keyword rankings, and site structure. Blocking prevents this. 2. **Crawl budget**: If your site is large, SEO tool crawlers consume crawl bandwidth without contributing to search rankings. Blocking frees up server resources for search engine bots. The trade-off: you also become invisible in Meltwater's backlink database, meaning links pointing TO your site from other domains won't appear in competitor reports either.
