Serpstat vs Sitebulb Comparison 2026
Serpstat does keyword research, rank tracking, backlink analysis and site audits from one account, priced under the bigger suites at $50 a month for Individual. Sitebulb only crawls and audits a site, explaining each finding, from $18 a month for Lite. Serpstat costs nearly three times as much at entry, buying a wider research toolkit; Sitebulb stays cheap and narrow, with no keyword or backlink data at all.

Serpstat
A full SEO suite at fifty dollars a month
Serpstat does keyword research, rank tracking, backlink analysis and site audits from one account, and prices the entry plan below where the better-known suites start. The data is thinner in some markets than Ahrefs or Semrush, which is the honest trade for the difference. For somebody checking a few hundred keywords a month rather than running an agency, the cheaper tier is not a compromised version of the tool, it is the same tool with lower limits.
Our note
The data is thinner than the market leaders in some regions, and that gap is the whole difference in price. Run the trial against keywords you already know the answer for, because that comparison tells you in an afternoon whether the cheaper tier is enough.

Sitebulb
A crawler that explains what it found
Sitebulb crawls a site and returns prioritised issues with an explanation of why each one matters, which is the difference between this and a spreadsheet of URLs. Crawl maps draw the structure of a site as a picture. JavaScript rendering is on every plan rather than reserved for the dearest. The desktop product audits ten thousand URLs at the entry tier, so anybody auditing a large site is looking at the cloud version instead.
Why people weigh these two
- Sitebulb instead of Serpstat
- Sitebulb only crawls a site and explains what it finds, starting at $18, sharper for a one-off technical audit than for the keyword tracking Serpstat is bought for.
- Serpstat instead of Sitebulb
- Serpstat is a full SEO suite at $50, the cheapest way to get crawling plus research together.
Which one should you pick
Pick Serpstat if you need keyword research, rank tracking and backlink analysis alongside the audit, at a price below Ahrefs or Semrush. Individual is $50 a month, and API access is not included at that tier, so factor in Team at $100 a month if automation matters.
Pick Sitebulb if a crawl and audit is genuinely the whole job. Lite is $18 a month, well under half of Serpstat's entry price, and every plan includes JavaScript crawling rather than reserving it for a dearer tier. There is no keyword or backlink data here at all.
Common questions
- Which one is cheaper?
- Sitebulb. Lite is $18 a month, against Serpstat's Individual plan at $50 a month, nearly three times more.
- Does Sitebulb check backlinks like Serpstat?
- No, backlink analysis is not in its feature list. Sitebulb is crawl and audit only. Serpstat's backlink reports return 2,000 results on its entry plan and 10,000 above it.
- Does Serpstat include API access at its cheapest tier?
- No. API credits are unavailable on Individual and only open up on Team at $100 a month or above.
- Is either one built for an agency running many client audits?
- Serpstat's Agency tier is built for that, at $410 a month with far higher export and backlink limits. Sitebulb's Pro plan raises seats to twelve for $42 a month, and a separate cloud product, priced on its own tab, suits very large sites better than the desktop version.
