## The short answer

Pick SpyFu when your job is to mine a rival’s organic and paid keyword history fast and build a target list. It is built for competitor research across search and ads.

Pick Semrush when you also need keyword discovery at scale, site audits, backlink research, and rank tracking in one place. It is a full SEO and PPC suite with Authority Score and advertising modules.

> If your day is running audits, content briefs and tracking positions, choose Semrush. If your day is spying on which keywords a domain has won or bought over time, choose SpyFu.

## What each reveals about a rival’s keywords

SpyFu centres on domains. You type a domain, you see the keywords it appears for and has advertised on historically. That makes it quick to copy a rival’s proven terms into your own plan.

Semrush gives you competitive research too, and adds Keyword Magic Tool for broad discovery. You can start from a seed like "invoice software" and branch into modifiers, questions and related ideas before you check who ranks.

- Use SpyFu when you know the rival domains that matter and want their organic and paid term history.
- Use Semrush when you also want to expand beyond rivals to build a whole topical map.

## Ad history and PPC insights

SpyFu is built around paid keyword history. You can see a domain’s ad terms and creative history over time. That helps you spot which messages likely persisted and which were dropped.

Semrush includes advertising modules. You can research competitors’ paid keywords and see sample ads alongside the rest of your SEO work. It suits teams that want PPC and SEO in one workspace rather than a specialist ad history view.

> No tool shows real budgets. Treat ad spend and traffic numbers as estimates and look for trends over time, not precise values.

## Backlinks, authority and site health

Semrush covers backlinks and site health. Backlink Analytics and Site Audit give you link profiles, Authority Score and technical issues to fix. That is useful when you must act on gaps you find in competitor research.

SpyFu is not a crawler or audit suite. Use it to find competitor keywords and ads, then switch to a crawler or a suite when you need audits or backlink analysis.

- Need a technical crawl or Core Web Vitals checks, use a crawler or Semrush Site Audit.
- Need to map a link gap versus rivals, use Semrush’s backlink tools or a dedicated backlink index.

## Tracking and reporting

Semrush Position Tracking monitors chosen keywords over time and reports movements. That closes the loop when you publish new pages and want to see results week by week.

SpyFu is strongest at discovery from a domain. You can export targets and build campaigns elsewhere. For ongoing rank tracking and audits, you will likely pair it with another tool.

## Side by side: where each fits

| Task | SpyFu | Semrush |
| --- | --- | --- |
| Find a rival’s historical paid keywords | Core use case | Included, within a broad suite |
| See a rival’s organic keyword footprint | Core use case | Included, plus seed-based discovery |
| Build a big keyword list from a seed | Limited | Keyword Magic Tool is built for this |
| Audit my site’s technical health | Not built for it | Site Audit is built for this |
| Research backlinks and authority | Not a focus | Backlink Analytics and Authority Score |
| Track rankings over time | Not a focus | Position Tracking is built for this |
| Produce all-in-one reports | Export and analyse elsewhere | Suite reporting across modules |

## What neither tool shows you

- Exact numbers. Treat traffic, spend and volume as directional. Use trends and relative gaps.
- Your own search performance. For your site’s real queries and clicks, use Google Search Console.
- Post-click behaviour. For sessions and conversions, use Google Analytics 4.
- Live crawl budgets or guarantees of indexation. Use Search Console and your logs for that.
- A rival’s content profitability. You will infer it from persistence in rankings and ads, not see their revenue.

## Worked example: turn a rival’s wins into your plan

Say you run yourproduct.com. Your main competitor is rivalsaas.com. You want to win small business intent on invoices and estimates.

1. **Pull the rival’s domain keywords in SpyFu** Enter rivalsaas.com and export organic and paid terms. Filter for terms that match your product, like "invoice template", "invoice software", "estimate app".
2. **Group by intent and stage** Split by pages. Map terms likely to land on /pricing, /guides/getting-started, and a new /templates hub.
3. **Check breadth in Semrush** Use Keyword Magic Tool with "invoice" as a seed. Add missed modifiers, like "free", "small business", and industry terms.
4. **Decide pages to build or improve** Create /templates/invoice-template with variants, and a guide for "how to make an invoice" linked from /guides/getting-started. Improve /pricing copy to match comparison intent.
5. **Plan tracking and fixes** Set Position Tracking for the target terms. Run Site Audit to fix blockers. Add internal links from your blog to the new pages.

A fixed set looks like this: /templates/invoice-template ranks for "invoice template", /guides/getting-started answers "how to make an invoice", and /pricing now captures "invoice software pricing" traffic with clearer copy and links.
