• You want an AI assistant that writes posts and social content: Enrich Labs.
• You want the posts written and published, title and description fixes applied when you press Apply, and AI search checked every week: Tilly. Try the free audit.

The entry price is high for one store. Semrush's SEO plan is $139 a month billed monthly, a fair price for an agency tracking several sites and a lot for a single Shopify store that writes two posts a month. source, checked 25 September 2026

It is built for many sites. The SEO plan monitors 5 websites and 500 keywords, and the tiers above it add more sites and markets. A store with one site pays for capacity it does not use. source, checked 25 September 2026

Research is not writing. Semrush gives you keyword research, competitor insight and an audit, and then the post still has to be written, illustrated and published by someone. For many small stores that is where SEO actually stalls. source, checked 25 September 2026

Each app’s cells come from its own Shopify listing or pricing page, linked beside the words. “Not listed” means we did not find it there, not that the app cannot do it. Tilly’s column is our own product.

Tilly does your Shopify marketing for you. It reads your product pages, your reviews and what customers ask, works out who buys from you and what stops them, and writes for those people: email flows and campaigns, blog posts, SEO fixes, Meta and Google ads, and fixes for the pages that lose you sales.

Everything waits for your approval, then goes where it belongs: emails into Klaviyo as drafts, posts onto your Shopify blog, ads into Meta and Google paused. Every night Tilly reads what each piece earned and writes the next one with what worked, so an ad angle that sells shows up in your subject lines and page headlines too. It also checks every week whether ChatGPT and other AI assistants recommend your store. Plans start at $79 a month, after 100 free credits.

Best for: a single Shopify store where SEO stalls at the writing stage. Tilly's SEO agent groups keywords by the questions your customers ask, writes the post with product links and a cover image, adds schema, and publishes to your Shopify blog when you approve it, then tracks it.

Watch out for: It is not a research suite. There is no competitor database or multi-site rank tracking; Tilly's research serves one store's posts. Agencies comparing many sites will still want a research tool.

Pricing: 100 free credits once. Then $49 a month for 500 credits; a post with its cover is 15 credits and the SEO audit is free.

Every price and limit in the table comes from the app's own pricing page or Shopify listing, linked and dated. Some of these tools publish annual prices only; the table says which. Tilly is on the list.

The second table prices the same store on each app. Semrush and Alli AI do not write the posts: they research and fix, and the writing stays with you or a writer. Surfer helps you write and optimise; Enrich Labs and Tilly write the posts themselves. Surfer’s prices are billed yearly.

Be honest about where your SEO stops. If you have posts planned and nobody to write them, a research tool will only make the list longer; you want something that writes and publishes. If you write well and guess at topics, research or on-page guidance is the gap.

Count sites, not features. Semrush and Alli AI price for several websites, and Surfer by documents. A single Shopify store writing a few posts a month should compare what it will actually use, not the top tier's feature list.

Check how each one gets content onto Shopify. Some tools stop at a draft you copy into the blog editor; Tilly publishes to your Shopify blog with the cover, meta fields and internal links in place. The copying step is where many posts quietly die.

Then give any choice a quarter. Organic search moves slowly, and a tool judged after two weeks has not had the chance to show anything. Compare impressions and clicks in Search Console at the start and after three months.
