If you're a solo builder or a small Shopify store owner, you've probably seen two very different ways to "do SEO without doing SEO." One is to hire a done-for-you service like FirstIndex. The other is to run self-serve software like RankReactorAI. This guide compares them honestly, using each product's own published pages, so you can pick the one that fits your budget and your stage.
The short version: FirstIndex is a hands-on service at $2,000 a month. RankReactorAI starts at $39 a month and does two jobs in one place: automated SEO content, and Buyer Radar, which finds people who are asking for what you sell right now.
What FirstIndex is
FirstIndex (firstindex.com) describes itself as "AI visibility and SEO for software companies, done for you." Its pitch is that real changes ship to your site every day, and a person checks each one before it goes live. The goal is to get your pages indexed, found in search, and mentioned by ChatGPT, Perplexity, Gemini, Claude, Copilot, Google and Bing.
According to its homepage, the monthly work can include:
- AI mention tracking, and fixing what AI tools get wrong about you
- Buyer and keyword research, plus a keyword map so pages don't compete with each other
- Up to 12 in-depth articles a month
- 50+ fixes to the pages you already have (titles, copy, speed, links)
- Comparison and "alternatives" pages, and free tools like calculators
- Index checks and index requests, and fact checks on your prices and claims
- Directory listings, link outreach, social posts for each new article, and a weekly report
Pricing: one plan at $2,000 a month. FirstIndex says it starts with 3 months, then goes month to month, or $1,500 a month if you sign up for 12 months. You start by emailing a one-sentence request, and they reply within one business day.
That's a real, serious offer. If you're a funded software company with budget and no one to own SEO, a human-checked daily program is a reasonable thing to buy.
What RankReactorAI is
RankReactorAI is self-serve software. You add your site as a project, and it measures the site, finds keyword opportunities, writes on-brand articles, and publishes them to your blog. On Pro and Ultra it also makes UGC-style videos from the same story.
Then there's the part that's different from FirstIndex and from almost every SEO tool: Buyer Radar.
Buyer Radar: the big difference
SEO brings people to you over months. Buyer Radar goes the other way and finds people who are asking for what you sell today.
Here's exactly what it does:
- It searches public posts on X and LinkedIn where people ask for what you sell.
- It scores each post for buying intent and shows you a link to the original post.
- It writes a draft reply or email for each lead.
- You review the draft, edit it if you like, and send it yourself with one click. Nothing is ever sent automatically, and RankReactorAI never posts for you.
Buyer Radar is on paid plans only, with monthly lead caps of 5 on Starter, 20 on Pro and 40 on Ultra.
FirstIndex's published service list covers search, AI answers, content and links. It doesn't list a feature that finds individual buyers' posts for you to reply to. That's the gap Buyer Radar fills. RankReactorAI's positioning is simple: it's the one place that gives you both automated SEO (articles published to your blog or Shopify store, plus UGC video) and an automatic search for buyers.
Side by side
- Model: FirstIndex is a done-for-you service with a person checking each change. RankReactorAI is software you run yourself, with a draft or approval step before anything publishes.
- Price: FirstIndex is $2,000/mo (3-month start, or $1,500/mo on a 12-month plan). RankReactorAI is Free ($0, 1 lifetime article), Starter $39/mo, Pro $79/mo or Ultra $159/mo.
- Articles: FirstIndex lists up to 12 in-depth articles a month. RankReactorAI generates 1 article per day on Starter, 3 on Pro and 5 on Ultra.
- Who it's for: FirstIndex says software companies. RankReactorAI is built for solo builders and small stores.
- Finding buyers: RankReactorAI has Buyer Radar on paid plans. FirstIndex doesn't list an equivalent.
- Video: RankReactorAI makes UGC-style videos on Pro (3 a month) and Ultra (10 a month). FirstIndex doesn't list video.
When to pick which
Pick FirstIndex if you run a software company, have the budget, and want an expert team to make and check changes on your site every day. A human reviewing technical fixes and existing pages is worth paying for at that stage.
Pick RankReactorAI if you're a solo builder or a small Shopify store, $2,000 a month isn't realistic, and you want both steady SEO content and a short list of real people asking for what you sell this week.
Step-by-step RankReactor playbook
Here's how to run the RankReactorAI side in an afternoon.
-
Check your site with the free tools. Before you pay anything, run your domain through the free tools at rankreactor.ai/tools. The Site Auditor, Keyword Intent Checker and Content Gap Analyzer show what's missing and which searches have buying intent.
-
Create a project. Sign up at rankreactor.ai and add your site as a project. RankReactorAI measures it and lists keyword opportunities.
-
Connect your blog. In Settings, open Blog connection and connect WordPress or a webhook. Leave publish mode on Draft and keep approval on at first, so you can read each article before it goes live.
-
Pick a paid plan. Starter is $39/mo and includes a 3-day trial after you add a project. It unlocks daily articles and Buyer Radar (5 leads a month). Choose Pro or Ultra if you want UGC video and more leads. See pricing.
-
Set up Buyer Radar. Open Buyer Radar from the dashboard. Add the phrases a buyer would write, like "alternative to [competitor]" or "need a [your category]". Add exclude terms for posts you don't want, such as job listings or other sellers. Set a minimum score.
-
Work your leads. For each lead, open the original post, read the draft reply or email, edit it so it sounds like you, and send it yourself with one click. Skip any lead that isn't a fit.
-
Publish and review weekly. Approve one or two articles a week that target buying-intent keywords, then check rankings and traffic in the dashboard. Keep the articles that bring visitors, and tune your Buyer Radar phrases based on which leads replied.
The bottom line
FirstIndex and RankReactorAI both want you found in search and AI answers. FirstIndex does it as a $2,000-a-month service. RankReactorAI does it as $39-a-month software and adds Buyer Radar, so you're not only waiting for search traffic, you're also replying to people who are asking for you today.
