Gyro-n SEO vs Semrush (2026): which should you pick?

Pick Gyro-n SEO if

• Fits if you report on Google and Yahoo! JAPAN rankings for a Japanese site
• Makes sense if you track a handful of Japanese keywords and want to know whether AI Overviews cite you

Look elsewhere if

• Not for you if you can't read Japanese, as the pages are in Japanese only and prices are in yen before tax
• Skip it if you need Google positions past 30th place, which it no longer measures
• Tight if you stay on Starter: 10 keywords, 1 site and no CSV export, and changing plan ends the free 3 months
• Pricey if you add Maps or Local Pack tracking, at ¥1,000 a month per store for the MEO option on top of a plan
• Watch out: extra keywords are ¥1,000 a month per 30, and extra sites and competitors ¥1,000 a month each

Pick Semrush if

• Fits if you want research, rank tracking and audits in one account and can pay $117.33 a month or more
• Works for agencies that need keyword data for many countries and compare client sites with competitors

Look elsewhere if

• Pricey if you're one person with one site, at $117.33 a month even yearly, and the trial checks your card with a small charge
• Tight if your team is more than just you, since every extra user is from $45 a month
• Skip it if AI answer tracking is the point, as the SEO plan leaves it out and Starter is $165.17 a month
• Watch out: the API and share of voice need the custom-priced Advanced plan, and scheduled PDF reports are $10 to $20 a month extra
• Watch out: local, content, social and ad tools are separate toolkits with their own prices, and the free plan allows 10 reports a day

Gyro-n SEO

• Prices are in yen before tax and the pages are in Japanese only; it tracks Google, Google smartphone search and Yahoo! JAPAN.
• Google positions are only measured to 30th place, a cap added after Google limited results per request; Yahoo! JAPAN pages are kept to 100th.
• Local Pack and Maps tracking need the MEO store option at ¥1,000 a month per store, on top of a plan.
• Extra keywords cost ¥1,000 a month per 30, up to 1,000 more for ¥30,000; extra sites and competitors cost ¥1,000 a month each.

Semrush

• Each plan includes one user; extra users start at $45 a month each, priced by plan level.
• Scheduled PDF reports are an add-on at $10 a month, or $20 with white-labeling; Advanced includes reporting.
• API access and share of voice come only with the custom-priced Advanced plan.
• Local, content, social, advertising, AI PR and traffic tools are separate toolkits with their own prices.

Semrush

Keyword research

Look up search volume, difficulty and intent from a database Semrush puts at 29 billion keywords across 142 country databases.

Competitor and backlink analysis

See which keywords and pages bring a rival site its traffic, and inspect any domain's backlink profile.

Position Tracking
