siteIQ vs SEMrush Free

What the paid suites do that siteIQ will not

Worth saying plainly, because a comparison page that claims the free tool wins at everything is not worth reading. Ahrefs and SEMrush run their own web crawlers at a scale that costs tens of millions to operate. That is what powers keyword volumes, difficulty scores, backlink graphs and competitor traffic estimates.

siteIQ has none of that and is not going to. If your work is finding keywords to target, watching rankings move week to week, or auditing a competitor's link profile, you need one of the paid suites and no free tool will substitute.

Where the free tiers actually stop

The friction is rarely the feature list — it is the metering. SEMrush's free account gives you about ten requests a day and roughly 100 crawled pages a month on one project. Ahrefs' free Webmaster Tools requires you to verify ownership of the domain, which rules out checking a prospect's site before a pitch. Ubersuggest gives you a few lookups then asks for a card.

All of that is reasonable business. It is also exactly the wall people hit at 4pm on a Thursday when they just want to know why a client's page is slow. That moment is the one siteIQ is built for: paste a URL, get the report, no account.

The checks the SEO suites skip

SEO tools audit for SEO. That sounds obvious until you notice what falls outside it. None of the big three will tell you that the SSL certificate expires in nine days, that Content-Security-Policy and HSTS are missing, that the detected WordPress version has a published CVE, or that the contrast ratio on the primary button fails WCAG AA.

Those are the findings that turn an audit into a conversation with a client about risk rather than rankings — and in our experience they are the ones that get budget approved.

A sensible setup

If you are a freelancer or small agency, a realistic stack is siteIQ for the technical and security pass on every site you touch, Google Search Console for real ranking and impression data, and one paid suite only when a client is actually paying for keyword and link work. That keeps the recurring cost tied to revenue instead of to hope.

Common questions

Is siteIQ a free alternative to SEMrush or Ahrefs?

For the technical audit half, yes. For keyword research, rank tracking and backlink analysis, no — and you should be sceptical of any free tool that claims otherwise. Those features depend on enormous proprietary crawl and clickstream databases that cost millions to build and maintain. siteIQ does not have one and does not pretend to.

What are the actual limits on SEMrush's free plan?

You need an account, and you are capped at roughly 10 requests per day across its reports, with the Site Audit limited to about 100 crawled pages per month and one project. It is a genuine trial of a serious product rather than a free tool. If you just want to check one site today, the signup and the cap are usually what send people looking elsewhere.

How does this compare to Ubersuggest?

Ubersuggest sits between the two. It offers a few free searches per day before prompting you to upgrade, and it is stronger than siteIQ on keyword ideas and content suggestions. siteIQ goes deeper on technical and security checks — security headers, SSL expiry, CVEs and WCAG are not things Ubersuggest reports on at all.

Why would I use siteIQ if I already pay for Ahrefs?

Mostly you would not, for keyword and link work. The one place it still earns its place is the security and accessibility layer, which the SEO suites leave out entirely — expiring certificates, missing headers, known CVEs in a detected WordPress version. That is a different category of problem from rankings.

Is there a catch with siteIQ being free?

No credit card and no trial clock. siteIQ is built and funded by Codaiman, a web development agency, and it exists partly because we needed it internally for client audits and partly as a front door to the agency. Some people run one audit and never come back, which is fine.
