Hi, I’m Kayla—here’s my deal

I run a small Shopify store for kitchen gear. I also help one B2B SaaS team on the side. So I live in two lanes: ecommerce and software. I watch rivals a lot. Not in a creepy way—more like, “What’s working for them, and can I do it better?”

You know what? The tools below didn’t just sit on my screen. I used them in real campaigns. I broke a few, too. That’s how this list happened.

If you want the even bigger nerd-out version, I keep a running teardown of the best competitor analysis tools I actually use over on my personal swipe file.

Need a primer on what makes a standout competitive-intel platform? The folks at Ahrefs put together a solid breakdown of competitor analysis tools that pairs nicely with my hands-on notes.

How I test tools (nothing fancy)

  • I set one clear goal. More traffic, cheaper ads, or stronger messaging.
  • I run side-by-side checks for two weeks.
  • I track one change that came from the tool. Then I judge the lift.

It’s not cute. But it’s real.


What I did:
I used Ahrefs to find keyword gaps against a big box rival for “cast iron skillet care.” Their blog ranked for “season cast iron with flaxseed oil.” I didn’t. With the Content Gap report, I found five related terms they owned.

What I changed:
I wrote one guide with simple steps, photos, and a short FAQ. I added two internal links from older posts. I also used the “Top pages” and “Backlinks” tabs to pitch three sites that linked to their post.

The result:
That page went from nowhere to page 1, spot 4, in 6 weeks. Two new links landed. Sales for our care kit bumped up 18% month over month.

What I like:

  • Clean keyword gap ideas that make sense
  • Strong link data and history
  • Rank tracking that doesn’t glitch on me

What bugs me:

  • Pricey if you’re solo
  • Some reports feel heavy; you can get lost

Best for:
Content teams, solo founders who bet on SEO, and folks who need link ideas fast.


2) SEMrush – Ads, SEO, and “who’s gunning for me” in one place

What I did:
I saw a rival bidding on my brand term for my skillet line. I used SEMrush’s Ads research to view their ad copy and the other keywords they kept over time. I mirrored the good parts, then added a “ships in 24 hours” line. I also found two long-tail terms they ignored.

The result:
Brand CPC dropped 22%. I pulled in cheaper clicks with those two long-tail terms. Not huge, but steady.

What I like:

  • Good PPC intel and ad history
  • Site audit pairs well with content work
  • Position tracking is steady

What bugs me:

  • Lots of tools inside one tool—can feel noisy
  • Traffic numbers for tiny sites can be off

Best for:
Teams that run both SEO and ads. If you wear many hats, this helps.


3) Similarweb – Where your rivals’ traffic actually comes from

What I did:
I checked a competitor’s traffic mix. I saw one food blog sending them 18% of referral traffic. That surprised me. I pitched that blog. I sent two recipes and one how-to post. We got a feature.

The result:
Referral traffic up 12% in that month. Those readers bought sets, not singles. Higher cart value too.

What I like:

  • Traffic sources are easy to read
  • Referral sites are gold for outreach
  • Good at “big picture” trends

What bugs me:

  • Small sites can look like a blur
  • Daily granularity isn’t great

If you’d rather grab the raw numbers yourself instead of relying on third-party panels, check out the web scraping tools that actually worked for me. They’re handy when APIs are locked or pricey.

Best for:
Partnerships, PR, and quick market reads.


4) SpyFu – Fast PPC spying when I need receipts

What I did:
I looked up a rival’s ad history for “nonstick pan.” They kept one headline for months. That told me it worked. I used a twist on that hook, but with a warranty angle. I also found three negative keywords I missed.

The result:
Lower spend waste. Better click-through. It wasn’t magic, but it paid for itself in one week.

What I like:

  • Simple view of what keywords stick
  • Historic ad copy that shows patterns
  • Affordable compared to big suites

What bugs me:

  • SEO data is fine, not great
  • UI is plain, but I don’t mind

Best for:
PPC folks, scrappy stores, and anyone who wants proof before writing ads.

Want to see how SpyFu itself stacks up against other options? Their team shared a helpful roundup of competitive analysis tools that complements the quick wins I list above.


What I did:
I checked the top shared posts about “carbon steel pan vs cast iron.” One competitor had a head-to-head guide with a chart. People loved the chart. I made my own test with heat spots and photos from my stove. I spun that visual up fast thanks to a couple of lightweight data visualization tools I’ve actually used.

The result:
Three cooking sites linked to it. A small YouTube channel used my chart and credited us. Organic traffic ticked up. Sales did, too.

What I like:

  • Clear view of what gets shared and by who
  • “Who linked to this” is handy
  • Alerts for topics and brand names

What bugs me:

  • Free plan is tight
  • Social counts change fast, so check dates

Best for:
Content teams, PR, and any brand that needs link bait that’s not gross.


6) Crayon – Watch rivals’ pages change (and beat them to the punch)

What I did:
Crayon pinged me when a rival added “Free Shipping Over $50” on their banner. I matched it in two days, but with a cleaner message: “Ships in 24 Hours, Free Over $50.” It also caught a pricing table tweak on their bundles.

The result:
Bundle sales rose 14% the next week. Could be mix of timing and copy. But the alert helped me move fast.

What I like:

  • Page change alerts on pricing, banners, and footers
  • Easy battlecards for the sales team at the SaaS gig
  • Good for launch tracking

What bugs me:

  • Setup takes time to get clean alerts
  • Can feel like too many pings if you track everyone

For deeper dashboards and cross-department reporting, I pair it with a few business intelligence tools that I actually use. They turn all those pings into something leadership will read.

Best for:
PMM folks, sales teams, and owners who need “what changed” without camping on sites.


7) BuiltWith (or Wappalyzer) – What tech stack your rival runs

What I did:
A competitor switched to Shopify 2.0 and added Klaviyo and Rebuy. I saw it the same day. That told me two things: they likely rebooted templates, and their email flows would heat up.

What I changed:
I cleaned my product pages, added a simple quiz, and moved my “email back-in-stock” higher on mobile.

The result:
More mobile adds to cart that week. Not a moonshot. Still worth it.

What I like:

  • Quick tech reads without guesswork
  • Great for B2B discovery too (my SaaS side loves this)

What bugs me:

  • Not every site is perfect in the results
  • No traffic or copy insights—pure tech

Best for:
Marketers who plan stack plays, agencies pitching, and nerds like me.


8) Brandwatch (or Brand24) – Keep an ear on the crowd

What I did:
I set alerts for my brand and two rivals. One rival had a spike in “late shipping” posts before a holiday. I pushed a simple ad: “Ships in 24 Hours. No drama.” It wasn’t snarky. Just clear.

The result:
Cheaper clicks that week and DMs asking “Is it really 24 hours?” Yep.

What I like:

  • Real-time alerts on keywords and tone
  • Good for spotting pain before it hits you
  • Nice for campaign timing

What bugs me:

  • Noise. You must filter well.
  • Learning tags takes a minute

Best for:
PR, social leads, and anyone who cares about timing.


Competition research isn’t just for cookware or SaaS. Even red-hot
