Search Console vs Semrush and Ahrefs: what each shows and when to use which
Search Console reports Google’s own counts for sites you can access. Semrush and Ahrefs build estimates from the keywords they track. They answer different questions, so the useful comparison is by data source, not by feature list.

Short answer
Use Search Console for the true clicks and impressions of your own site, and a third-party tool for what Search Console cannot show: other sites and keywords you do not yet rank for. Treat the third-party traffic figures as estimates, which the vendors themselves say they are.
Search Console’s own definition is on the Performance report overview ↗ .
How to decide, step by step
The vendor statements below are quoted from their own help pages.
Ask where the number comes from
Search Console counts real clicks and impressions in Google Search for your verified property. Ahrefs says its organic traffic is calculated from the keywords it sees a site ranking for and their search volume. Semrush bases its estimated traffic on keywords where a domain ranks in Google’s top 100.
Use Search Console for your own truth
For your own site it is Google’s count, with its own limits: rare queries are omitted and the table shows at most 1,000 rows.
Use a third-party tool for what you cannot see
Only an outside tool can estimate a competitor’s traffic or show keywords you do not rank for yet. Ahrefs notes that a competitor’s actual keywords and pages are more accurate than its big-picture traffic estimate.
Compare for direction, not for totals
Ahrefs says marketers use its data to compare websites and see trends. Do the same: read third-party numbers as relative.
Expect a mismatch with your own numbers
Ahrefs lists why: it does not track all keywords, its volume is modelled from Keyword Planner and clickstream data, and a CTR model estimates clicks. It states the figure cannot be treated as actual traffic.
Combine them where it helps
Semrush’s Organic Traffic Insights puts Google Analytics, Search Console and Semrush data in one dashboard, so you can read the two sources side by side.
Questions people ask most
For your own clicks and impressions, Search Console, because it is Google’s own count. Third-party tools estimate and say so.
Ahrefs gives three reasons: it tracks only the most popular keywords, its search volume is a modelled estimate, and it estimates clicks with a CTR model because only Google knows the real click numbers.
Semrush reports from keywords where the domain has an organic position in Google’s top 100, while Search Console lists the queries that actually produced impressions for you.
No. It covers only properties you have access to; competitor estimates need a third-party tool, with the caveats above.
It depends on the question. For a site you run, Search Console is the base. For competitive research, an outside tool is the only option.
DATA SOURCES
Estimates are useful when you know they are estimates
An estimate that is wrong by a constant factor still ranks sites and shows direction, which is what it is good for. It becomes misleading when you read its absolute number as your traffic or use its search volume to judge your own clicks.
Where SEOKit stands
SEOKit works on your own Search Console and GA4 data. It has no keyword database and does not estimate other sites’ traffic, so it complements an outside research tool rather than replacing one.
Common mistakes
Do not read a tool’s traffic estimate as your analytics
Use Search Console or GA4 for your own traffic.
Do not judge your clicks by a third-party search volume
Volume is modelled; your impressions and clicks are counted.
Do not compare tools by totals
Compare direction and relative position.
