What CSV columns does LinkJuice need exactly?

[pete_t]

I got an 'invalid format' error when uploading. What are the exact column headers LinkJuice expects? Can I use a custom crawler instead of Screaming Frog?

LinkJuice expects the standard Screaming Frog All Inlinks CSV format. The required columns are: Source, Destination, Link Type, Status Code.

If you're using a custom crawler, you can map your columns to these names. The column names are case-insensitive. Make sure URLs are absolute (starting with https://).

Just to add to what's been said — I ran into the same issue last month. The key for me was checking the crawl was set to JavaScript rendering mode. That doubled the number of links Screaming Frog found and the LinkJuice PageRank shifted noticeably for several pages.

One thing I'd add: even if the scores look confusing at first, sort by PageRank descending and compare the top 10 against your GA4 sessions. The correlation is usually clear. High-traffic pages should also have high internal PageRank — if they don't, you've found a real problem.
