Compare your rankings with competitors
A head-to-head SEO visibility and share-of-voice comparison — for the keywords you track. Add a rival's domain and RankNibbler shows how your organic visibility stacks up against theirs across your tracked keywords: who's more visible, who ranks for more of your terms, and exactly who's outranking you. Free, focused, and built straight from your rank tracking.
Compare your visibility with competitors
Rankings only mean so much in isolation — what you really want to know is how you compare to the people you're up against. Add your competitors and you get a side-by-side view: your visibility score next to each rival's, and how many of your tracked keywords each of you ranks for. At a glance you can see whether you're ahead, level, or being out-muscled — and by how much.
Competitor rank tracking, automatically
There's nothing extra to set up. For every keyword you track, RankNibbler captures the full top 100 results — so it already knows where each competitor sits relative to you. That means for any keyword you can see who ranks above and below you, and across all your keywords it adds up to a clear picture of where you're winning and where you're losing ground.
SEO visibility and share of voice, explained
The comparison is built on share of voice — the share of the total estimated clicks across your tracked keywords that each domain captures. It's weighted by search volume and position, not just average rank, so a competitor ranking #1 for your big terms counts for far more than one scraping the bottom of page one for a rare query. The underlying visibility score is simple:
- For each tracked keyword a domain ranks for:
- expected click-through rate for its position × the keyword's search volume
- …summed across every keyword it ranks for.
Compare those numbers across you and your rivals and you've got your share of voice — a single, honest measure of who's most visible for the searches that matter to you.
Find and add your competitors
Not sure who to add? RankNibbler can suggest competitors for you with AI, based on the keywords you track — so you start with the right rivals, not a guess. Or just paste in the domains you already know you're up against. The free tier compares you against up to 3 competitors.
Focused on purpose
This isn't a sprawling competitor-research suite, and that's deliberate. Tools like the big paid suites estimate a rival's entire footprint — total traffic, every keyword, all their backlinks — which is a lot of noise when you just want to know how you compare on the terms you actually care about. RankNibbler keeps it to a clean head-to-head on the keywords you track: no spreadsheet, no noise, no subscription.
