Webflow does not use plugins in the traditional WordPress sense. Instead, it has Apps available through the Webflow Marketplace. The difference matters because Webflow already includes many native SEO controls, such as metadata, redirects, sitemaps, robots.txt settings, and clean page structure.
Apps are mainly used to extend workflows, automate tasks, run audits, or connect Webflow with external tools. Unlike many WordPress plugins, Webflow apps usually connect through approved integrations or APIs, which helps reduce compatibility and performance issues. In this guide, we’ll look at the best Webflow plugins and apps, what they do, and when they are worth adding to your site.
I've tested 20+ Webflow SEO apps across client projects. The six below are the ones I actually keep installed. Each listed app matches these criteria:
These six are the ones I keep coming back to, each handling a different part of the workflow.
Apps covered in this guide:
Semflow runs as a panel inside the Webflow Designer, so you get SEO feedback while you're building instead of waiting until after you publish. It scans your static pages and CMS items, scores each one against on-page checks (title length, meta description, headings, internal links, alt text), and gives you a prioritized list of fixes. Keyword research is built in too, so you can find target terms, assign a primary and secondary keyword per page, and track rankings over time.
The no-code schema builder matters because Webflow's native custom code field gets messy fast once you have more than a handful of pages, and Semflow covers the main types most sites need. PageSpeed Insights is wired in for both desktop and mobile, and PDF client reports sit alongside everything else, so agencies running multiple Webflow sites don't have to bolt on a separate reporting tool.
If you're running multiple Webflow sites, Semflow is the closest thing to an all-in-one option on the Marketplace.
Key Features
Best For: Designers who want SEO feedback while they're building, and agencies running multiple client sites who need PDF reports and rank tracking in one place.
Pros
Cons
Pricing: Free trial available with limited pages; paid plans start from $8/month.
AI SEO Copilot opens as a panel inside the Webflow Designer and runs 18 on-page checks against whichever page you're currently working on. It looks at title tag length, meta description, H1 usage, image alt text, keyword placement, and the other on-page basics, then flags what's missing or off. What sets it apart from a generic checklist app is the GPT-powered explanations; instead of saying "your meta description is too long," it tells you exactly how to shorten it and why that matters for click-through rate.
The keyword presence detection is useful for confirming your target term actually appears in the places that count (title, H1, first paragraph, alt text) before you publish. Documentation sits inside the Designer too, so you don't have to leave Webflow to figure out what a check means. The app is free and open source with monthly community updates, and the only cost is your own OpenAI key if you want the AI fix suggestions turned on.
Key Features
Best For: Solo founders, freelancers, and beginners learning SEO. Also a fit for budget-conscious agencies that want a free starting point before paying for a heavier tool.
Pros
Cons
Pricing: Completely free: no paid tier, no signup, no credit card.
Graphite installs into Webflow and handles the usual SEO basics (bulk meta editing, schema, robots.txt), but the reason most teams pick it is the AI Tracker. It monitors whether your Webflow pages get cited in ChatGPT, Perplexity, Claude, Gemini, and Google's AI Overviews, then shows your share of voice against competitors for the prompts you care about.
The bulk meta editor handles titles, descriptions, and OG images across static and CMS pages from one screen, which covers the day-to-day work the AI Tracker doesn't. There's also a Webflow-specific feature most apps skip, which is per-page control over whether LLM crawlers can train on your content versus just index it.
For Webflow content sites that want to show up in AI answers and not just Google, this is one of the best Marketplace apps currently built around that goal.
Key Features
Best For: Marketing teams and content strategists who want to show up in ChatGPT and Perplexity, not just Google.
Pros
Cons
Pricing: Free plan available on the Webflow Marketplace; paid pricing isn't publicly disclosed.
FluidSEO runs inside the Webflow Designer and focuses on the parts of SEO that get painful once a site grows past 100 pages. It audits every page, generates alt text in bulk (including for CMS images, which most other apps can't touch), and pushes meta titles and descriptions across the site in one click.
The CMS image support is the real reason to use it; if you have a blog with 200 posts and 5 images per post, writing alt text by hand is hours of work, and Webflow's native asset panel doesn't help with images stored in CMS fields. The audit side flags broken metadata, missing schema, and duplicate titles across the whole site, and the CSV bulk update is a useful extra for migrations, though it doesn't extend to CMS items yet.
Key Features
Best For: Webflow agencies and freelancers managing large client sites. Also a fit for in-house marketing teams handling 100+ page sites with image-heavy CMS content.
Pros
Cons
Pricing: Free plan; paid plans start from $24/user/month (Business) or $65/month (Agency, unlimited users)
Schema Flow is the tool you reach for when your Webflow site has CMS collections, and you want every item to publish with proper structured data. You map a CMS field (like "Author Name" or "Published Date") to a schema property once, and from then on, every new collection item gets JSON-LD generated automatically with no extra work per post. It covers 13+ schema types out of the box (Article, Product, LocalBusiness, FAQ, Recipe, Event, and others) and lets you paste raw JSON-LD if you need something custom.
The visual editor for JSON-LD helps a lot here, because writing schema by hand inside Webflow's custom code field is error-prone, and a single missing comma can break the whole markup. The CMS filtering is a nice touch for sites that want different schema on different content types within the same collection, like applying Recipe schema only to posts tagged as recipes.
Key Features
Best for: Developers, technical SEOs, and agencies who need schema at scale across CMS-driven sites without writing JSON-LD by hand.
Pros
Cons
Pricing: Free Starter (up to 10 schemas); Pro at $79 one-time for lifetime access.
BulkSEO does one thing and does it fast: editing metadata across an entire Webflow site from a single screen. You see every page (static and CMS items) in one list, edit titles, descriptions, and Open Graph fields inline, and push the changes live in one click.
The CSV import/export is what makes it stand out for migrations; you export the current metadata, edit in a spreadsheet (or hand it to a copywriter), and reimport when you're done. Open Graph and SEO fields stay synced by default, and the global OG image setting applies to every page that doesn't have its own.
It doesn’t perform audits, schema, or AI generation, but if your job today is "rewrite metadata on 300 pages," nothing else on this list is faster.
Key features
Best For: Migration specialists, freelancers, and agencies doing site relaunches. Also a fit for marketing teams doing periodic site-wide metadata refreshes.
Pros
Cons
The process works the same for any Marketplace app. Here's the universal workflow that I've refined through dozens of installations.
Navigate to webflow.com/apps or click Apps in the left sidebar of Designer. Filter by "SEO" category or search by app name. Review the install tier, and check the last updated date. Remember that abandoned apps cause problems.
Click “Install,” "Add to site," select your workspace, then choose your specific project.
Review requested permissions carefully. Some apps request Designer access, which means they can modify your site. Others only request Content access, which means they can read but not change. Authorize only what's necessary.
Follow the app-specific onboarding. Each tool varies.
Common configurations include API keys, target keywords, audit frequency, and notification preferences. I always run an initial audit to establish a baseline before making changes.
Three checks I run after every app installation are the following:
Compare before and after. If performance drops, investigate or remove the app.
Most Webflow sites don't need more than two or three SEO apps. The trick is picking the ones that fit your workflow instead of duplicating what Webflow already does well.
Pick by problem, not by app category. If you're losing track of metadata across hundreds of pages, you need bulk editing (BulkSEO or FluidSEO). If your CMS-driven blog isn't getting rich results in search, you need schema automation (Schema Flow). If your site is invisible in ChatGPT and Perplexity, you need AEO tooling (Graphite). If you're a designer who wants SEO feedback while building, you need in-Designer auditing (Semflow or AI SEO Copilot).
Pick the problem that's costing you the most time or traffic. That's your first app.
This is where most teams overspend. Schema Flow and FluidSEO both touch schema, but they're not interchangeable: FluidSEO handles basic Article and Organization schema, while Schema Flow covers a much wider range of schema types with CMS automation. Pick FluidSEO's schema if you only need the basics; pick Schema Flow if you need anything more.
A clean stack usually looks like one auditing tool (Semflow, FluidSEO, or AI SEO Copilot), one specialist tool for whatever your audit tool doesn't handle (Schema Flow for CMS schema, Graphite for AEO, or BulkSEO for CSV-based bulk edits), and Google Search Console for everything else.
Most apps on this list offer a free tier (Semflow is trial-only), so cost only matters once you outgrow the free plan. For paid options, the math depends on how long you'll use them.
Schema Flow Pro at $79 one-time and BulkSEO+ at $50 one-time pay for themselves within a few projects. FluidSEO and Semflow run on subscriptions, so calculate the annual cost against the time saved. If FluidSEO Business at $24/user/month saves you 5 hours per month, that's under $5 per hour for your time back.
DIY works when your site has fewer than 50 pages, straightforward content, and basic technical SEO requirements, and you have time to learn them.
Hire an agency when you're facing large-scale migrations (100+ pages with complex redirect mapping), competitive industries that require sustained link-building, technical issues beyond app capabilities (JavaScript rendering, international SEO, or programmatic page generation), or strategic guidance you don't have time to develop in-house (keyword research, content strategy, competitive analysis, or AEO positioning).
Take Borderless AI, an Employer of Record platform competing in a SaaS market. The work with them combined a deep technical audit, 100+ pieces of content mapped to buyer journey stages, and multi-channel link building (SaaS partnerships, a scholarship campaign, and AIO outreach). In under a year, organic traffic grew from 4,300 to 9,800 monthly visitors, domain rating moved from 34 to 55, and the site earned 210 high-quality backlinks. That's the scale of work apps can't replicate.
If your situation is closer to Borderless AI's than to the simple cases above, this is the kind of work our Webflow SEO services take on.
