<b>Ahrefs vs Semrush for keyword gap analysis</b>

<b>Ahrefs vs Semrush for keyword gap analysis</b>
I ran the same 3 competitors through both on a real SaaS account.

<b>Ahrefs Content Gap</b>
➕ Cleaner UI: paste up to 10 competitors, filter by "all of the below rank"
➕ Keyword difficulty is conservative, fewer false-easy wins
➖ Caps you on the lower plans (Lite = 500 rows/report)

<b>Semrush Keyword Gap</b>
➕ The 4-quadrant venn (shared/missing/weak/untapped) is genuinely faster to read
➕ Pulls in paid keywords too, useful if you also run ads
➖ US database is great, smaller markets get thin

<b>Best for:</b> Ahrefs if your edits hinge on accurate difficulty. Semrush if you want the gap visualized and you touch paid.

<b>Price-vs-value:</b> roughly the same tier (~$129-139/mo entry). Neither is "cheaper" — pick on workflow, not price.

Pick this if you only buy one and you're organic-only: Ahrefs.
Skip if you need both organic + paid in one screen: get Semrush.

Affiliate-neutral: I get nothing if you buy either.
