Visibillity competitor comparison
A visibillity comparison graph (like Semrush, Sistrix and Search Metrics) would make Ahrefs (almost) complete. I would happily cancel my Sistrix subscription if Ahrefs could provide that 👌🏻
TLDs comparison: local market share
There doesn't currently seem to be any reports that allow a comparison across TLDs for international websites of how well is a local TLD stacking against international TLDs (same website). Large international brands with dozens of TLDs often run into issues with their international TLDs outranking the local ones in the local SERPs. There's few data sources that would allow stacking all international domains side by side and comparing how well they do in their local markets. A subsection of the competing domains report could focus on how the TLD in question stacks up against other TLDs of the same website in that local market.
Add new feature to Domain Comparison (or create separate "URL comparison"?) where you could compare URLs from the same or from different domains.
Add min/max position filter to Competing Domains
Would love to filter competing domains based on where the mutual keywords are positioned in SERPs. For example, I'd love to see how many domains are also appearing within ONLY the top 10 positions for the same keywords. This gives me a more focused view on my strongest competitors.
Add data to Domain Comparison tool
Add annual traffic volume and total keywords by selected country for each domain compared. I can then cancel my SEMrush subscription :)
