Brass-SEO vs Semrush: What a Small Business Actually Needs
Semrush is one of the most respected SEO platforms in the industry. It offers keyword research, backlink analysis, site audits, rank tracking, competitive intelligence, and content marketing tools — all in one subscription. It is built for SEO professionals, agencies, and marketing teams who need deep data access across multiple domains.
Brass-SEO is a different kind of tool. It connects to your Google Search Console and Google Analytics 4 accounts and lets you ask SEO questions in plain English. It is built for business owners who want to understand their website's performance without becoming SEO experts.
These are not competing products in the traditional sense. They solve different problems for different people. Here is an honest look at what each one does, who it is for, and when each makes sense.

What Semrush Does Well
Semrush maintains its own massive database of keywords, backlinks, and website data. It crawls the web independently from Google, which means it can show you data about any website — not just your own. This is its core strength.
Where Semrush excels:
- Competitive research — See what keywords your competitors rank for, what backlinks they have, and how their traffic compares to yours
- Keyword research at scale — Explore keyword ideas with search volume estimates, difficulty scores, and SERP features
- Backlink analysis — Detailed backlink profiles for any domain, with toxic link identification
- Large-scale site audits — Crawl thousands of pages for technical SEO issues
- Rank tracking — Monitor keyword positions over time across multiple search engines
- PPC research — Analyze competitors' paid search campaigns
Semrush is comprehensive. For an agency managing 20 client websites, having all of this in one platform is genuinely valuable. The breadth of features is a real advantage when your job is SEO.
What Brass-SEO Does Differently
Brass-SEO takes a fundamentally different approach. Instead of building its own data, it connects to the data Google already collects about your website through GSC and GA4, both of which are required for a complete picture.
For more on these data sources, see the GSC guide and GA4 guide.
Where Brass-SEO focuses:
- Plain-English answers — Ask "How is my organic traffic this month?" instead of navigating reports
- First-party data — Uses your actual Google data, not third-party estimates
- Cross-referencing — Combines GSC search data with GA4 behavior data automatically
- Actionable recommendations — Identifies what to fix next, not just what the data shows
- Page-level analysis — Audits individual pages for SEO issues
- Indexing checks — Verifies whether Google has indexed your pages
The trade-off is clear: Brass-SEO cannot show you competitor data, does not have its own keyword database, and does not track backlinks. What it does is make your own data understandable and actionable.
Feature Comparison

|---|---|---|

| Social media tracking | Yes | No |
| GSC data integration | Limited | Core feature (first-party data) |

| Cross-source analysis | Manual | Automatic (GSC + GA4 combined) |

Pricing Comparison
Pricing as of early 2026 (check current pricing on each tool's website):
| Plan | Semrush | Brass-SEO |
|---|---|---|
| Entry level | Pro: $139.95/month | $25/month |
| Mid tier | Guru: $249.95/month | — |
| Enterprise | Business: $499.95/month | — |
| Free trial | 7 days | 3 days |
| Annual discount | Available | — |
Semrush's pricing reflects the breadth of its platform. For agencies billing clients hundreds of dollars a month for SEO, the cost is a fraction of revenue. For a small business owner paying out of pocket, the calculus is different.
The question is not "which tool costs less?" but "which tool gives me what I need at a price I can sustain?"
Who Should Use Semrush
Semrush is the right choice if:
- You are an SEO professional or agency managing multiple clients
- Competitive keyword research is central to your strategy
- You need detailed backlink data for link-building campaigns
- You manage a site with thousands of pages needing regular technical audits
- You run both SEO and PPC and want the data in one platform
- You have an SEO team that can act on the volume of data Semrush provides
Semrush earns its price for users who leverage its full feature set. An agency running competitive audits, building link strategies, and tracking hundreds of keywords across multiple domains will use most of what they are paying for.

Who Should Use Brass-SEO
Brass-SEO is designed for business owners who want to understand their own site's SEO performance without learning complex tools or paying enterprise prices.
Brass-SEO is the right choice if:
- You are a business owner who wants to understand your own site's SEO
- You do not have time to learn enterprise SEO tools
- You want answers, not dashboards
- Your budget is limited and you need the basics covered well
- You want your actual Google data interpreted, not third-party estimates
- You prefer asking questions over navigating complex interfaces
Brass-SEO is designed for the business owner who checks their SEO once a week or once a month. Connect your GSC and GA4, ask what is happening, and get a clear answer with specific recommendations. The first analysis walkthrough shows exactly what this looks like in practice.
Can You Use Both?
Yes, and some users do. Semrush gives you competitive intelligence and keyword research. Brass-SEO gives you a fast, conversational way to check your own site's performance. They do not overlap much.
That said, most small businesses do not need both. If your SEO work mainly involves understanding and improving your own website, Brass-SEO plus Google's free tools covers it. If you are actively building backlinks, running competitive campaigns, or managing SEO as a profession, Semrush is worth the investment.
The honest answer is that most small business owners overestimate how much competitive data they need. Knowing what keywords you already rank for, which pages need work, and whether your traffic is growing tells you what to do next. You do not need to know what every competitor is doing to improve your own site.

Frequently Asked Questions
Does Brass-SEO use Semrush data?
No. Brass-SEO connects directly to your Google Search Console and Google Analytics 4 accounts. All data comes from Google's own APIs. This means you get your actual performance data — real impressions, real clicks, real traffic — rather than estimates from a third-party crawler.
Is Semrush's keyword data more accurate than GSC data?
They measure different things. Semrush estimates search volume and keyword difficulty based on its own crawl data. GSC shows you the actual queries that triggered impressions and clicks on your site. For understanding your own performance, GSC data is more reliable because it is your real data. For exploring keywords you do not rank for yet, Semrush's database is useful.
Can I switch from Semrush to Brass-SEO?
Yes, but understand what you are trading. You gain simplicity, lower cost, and conversational access to your data. You lose competitive keyword research, backlink analysis, and large-scale site auditing. If you used Semrush mainly to check your own site's performance, the switch is straightforward. If competitive research was a core workflow, you will miss that capability.
Does Brass-SEO offer rank tracking like Semrush?
Brass-SEO shows your keyword positions from GSC data, which is updated daily by Google. You can ask "What are my top keywords?" or "How have my rankings changed?" and get current answers. It does not offer the dedicated rank tracking dashboards with historical charts that Semrush provides. For most small businesses, GSC position data is sufficient because it shows your actual rankings, not estimated ones.
Why is Brass-SEO so much cheaper than Semrush?
Different scope, different infrastructure. Semrush maintains its own web crawler, keyword database, and backlink index across hundreds of millions of domains. That infrastructure is expensive to build and maintain, which is reflected in the price. Brass-SEO leverages data Google already collects and provides free through its APIs. The value Brass-SEO adds is interpretation and cross-referencing, not data collection.
