Mageworx SEO Suite Ultimate vs Semrush (2026): which should you pick?

Pick Mageworx SEO Suite Ultimate if

• Fits if you run a large Magento 2 or Adobe Commerce catalog
• Makes sense if you'd rather pay once than subscribe

Look elsewhere if

• Skip it if your store isn't on Magento 2.4 or Adobe Commerce
• Pricey if you're on Adobe Commerce, where the same extension is $598
• Watch out: updates and support stop after a year unless you renew at 40% off the list price
• Watch out: installation ($69), priority support ($99) and SEO configuration ($349) are extras
• Not for you if you want to try it first: there's no trial, and Marketplace copies get 25 days for returns, not 60

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

SEO templates

Fill in meta titles, descriptions, keywords and other values in bulk for products and categories from templates, instead of page by page.

Rich snippets and sitemaps

Adds product and category rich snippets, Open Graph and Twitter Cards, breadcrumbs markup, and XML and HTML sitemaps that split for catalogs over 50,000 links.

Cross-linking and redirects

Turns chosen keywords into links to products, categories or CMS pages, redirects deleted products automatically, and imports custom 301 and 302 redirects from CSV.

SEO reports

Reports duplicate, missing, too long or too short meta titles, descriptions, names and URLs across product, category and CMS pages.

AI writing and llms.txt

Generates meta tags and descriptions with OpenAI or Google Gemini, and builds llms.txt files for AI assistants while tracking visits from verified AI crawlers.

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

Track daily rankings for 500 to 5,000+ keywords depending on the plan; Pro+ adds tracking by location and device.

Site Audit

Crawl your sites for technical SEO problems. From the Starter plan the audit also checks how ready a site is for AI search.

AI visibility tracking

Starter and above track daily whether set prompts in AI chat tools mention your brand, with sentiment monitoring. The SEO plan has none of this.

MCP and API access

Starter and above can query Semrush data from AI assistants through MCP; the API itself comes with the Advanced plan.
