Similarweb Top 30 Rankings Refresh Every 72 Hours – Ranktracker Is Daily

Intro

If you’re looking into Similarweb rank tracking, there’s an important limitation that often gets missed because Similarweb is better known for traffic data than for SERP accuracy.

Similarweb tracks rankings only up to the Top 30, and those rankings are refreshed roughly every 72 hours, not daily.

That makes it a high-level monitoring tool, not a full-depth, real-time rank tracker.

How Similarweb rank tracking actually works

Similarweb’s rank tracking is designed for trend analysis, not day-to-day SEO execution.

In practice, this means:

• Tracks rankings positions 1–30 only
• Rankings refresh every ~72 hours
• No daily updates
• No visibility into positions 31–100
• Limited historical resolution for short-term changes

If a keyword ranks at position 42, 67, or 91, Similarweb does not track it at all.

What a 72-hour refresh looks like in real SEO work

When rankings update every three days:

• Short-term movement is hidden
• SEO tests feel delayed
• Cause-and-effect is hard to confirm
• Volatility is smoothed over
• Competitor changes appear late

Example:

• Monday: keyword moves from position 28 → 22
• Tuesday: drops to 25
• Wednesday: rises to 21

In Similarweb, you’ll likely see one number — once the refresh runs.

Everything in between is lost.

Why Top 30-only tracking is still a problem

Even with perfect speed, Top 30 depth isn’t enough for most SEO workflows.

Real progress usually starts here:

• Page 10 → Page 7
• Page 7 → Page 5
• Page 5 → Page 4

Those are positions 31–100 — exactly where Similarweb stops tracking entirely.

So you lose visibility twice:

• First by depth (Top 30 only)
• Second by frequency (every 72 hours)

The blind spots this creates

With Top 30 + 72-hour refreshes, you cannot:

• Validate SEO changes quickly
• See early momentum building
• Spot competitors before they break page three
• Diagnose volatility accurately
• Understand why rankings changed

SEO becomes reactive instead of proactive.

How Ranktracker handles rank tracking differently

Ranktracker was rebuilt specifically for full-depth, daily SERP tracking.

With Ranktracker:

• Positions 1–100 are tracked
• Updates run daily
• No refresh delays
• No depth limits
• Full historical daily data
• Clear competitor visibility

If a keyword moves today — whether it’s position 14 or 84 — you see it tomorrow.

Similarweb vs Ranktracker in simple terms

Similarweb

• Tracks only Top 30
• Refreshes every ~72 hours
• No visibility beyond page three
• Designed for trend analysis

Ranktracker

• Tracks full Top 100
• Updates daily
• Complete SERP visibility
• Built for active SEO decision-making

One shows broad trends. The other shows what’s actually happening.

Who Similarweb rank tracking works best for

Similarweb can be useful if:

• You want high-level visibility
• Trend analysis matters more than precision
• Rank tracking is secondary to traffic research

But if your SEO depends on:

• Daily monitoring
• Fast feedback loops
• Tracking growth before page three
• Spotting competitors early

Then Similarweb’s rank tracking is too shallow and too slow.

Bottom line

Similarweb tracks only the Top 30 rankings and refreshes them every 72 hours. Positions 31–100 are not tracked at all.

Ranktracker tracks the full Top 100 every day, with no blind spots, no delays, and complete historical context.

If you want to understand how rankings actually move — not just general trends — daily Top 100 tracking matters.
