SEO 플러그인·앱 무료 가이드

저희가 꼽은 SEO 플러그인·앱 상위 3개

Slim SEO comes first: its free WordPress plugin writes meta tags, schema and sitemaps on its own and handles redirects and 404s, which Yoast, AIOSEO and SEOPress keep for paid plans. SEO King is second for Shopify stores, and SmartCrawl third for WordPress writers who want post checks and a schema builder in the free plugin. Yoast SEO narrowly missed: its free plugin checks one keyphrase and has no redirects or link suggestions, and Premium is $118.80 a year for each site before VAT.

  1. 1위: Slim SEO

    무료 플랜 · $59/년부터

    용도: Most WordPress site owners

    Slim SEO writes meta titles, descriptions, robots and social tags, connected JSON-LD schema, XML, image and News sitemaps and breadcrumbs from each post with no setup, and the free plugin also handles redirect rules and logs 404s. Personal is $59 a year for one site and renews at the same price, adding a schema builder with 30+ types, link suggestions, Search Console reports and a writing assistant. Know the limits: it runs only on self-hosted WordPress, AI meta writing uses your own OpenAI, Gemini, Claude or OpenRouter key billed by that provider, and writing tips while you draft are Pro only.

  2. 2위: SEO King

    무료 플랜 · $9.99/월부터

    용도: Shopify store owners

    SEO King scans a Shopify store and lists fixes, edits meta titles, descriptions and alt text, renames and compresses photos, finds broken links and 404s, manages redirects and shows Search Console stats; the free basics have no stated cap. Paid tiers add unlimited AI meta text, robots.txt and llms.txt editing and advanced JSON-LD, from $9.99 every 30 days for 500 pages to $16.99 for 20,000. It is second because it works only on Shopify, the free basics write no AI text, and Vision AI alt text, translation and background removal are paid per use from prepaid credits.

  3. 3위: SmartCrawl

    무료 플랜 · $50/년부터

    용도: WordPress writers who want post checks in the free plugin

    SmartCrawl's free WordPress plugin sets title formats, builds XML sitemaps, adds social tags and 301 redirects, has a schema types builder, and grades each post for keyword use and readability in the editor, after a setup wizard and an SEO checkup. Pro Basic is $50 a year for one site. It is third because there are title formats, sitemap types and schema to choose before it is done, where Slim SEO fills these in on its own, and Pro is not sold alone: every paid plan is WPMU DEV's bundle of Pro plugins, with scheduled audits, auto-linking, IndexNow and regex redirects held there.
