What each one
is actually better at

We are not going to pretend Moz Pro is bad. It is not. Here is the honest split.

Where SlapMyWeb wins
  • Delivers a deeper single-site audit: 240+ checks scored into 8 pillars, including Speed, Security, Mobile and Accessibility, not just crawl and on-page issues.
  • Generates fix code for each issue, so an audit ends in changes a developer can make rather than a list of affected URLs.
  • Includes deep-audit modules that Moz Pro's Site Crawl does not focus on: WCAG 2.2 AA accessibility via axe-core, security and compliance, JavaScript rendering, and conversion heuristics.
  • Measures Core Web Vitals with PageSpeed Insights v5 and CrUX field data inside the same scan.
  • Has a usable free tier of 10 scans a day with the full issue list, and Pro is $9/mo against Moz Pro's ~$49/mo Starter plan.
  • Writes its verdict in plain English with a prioritized action plan aimed at site owners as well as SEOs.

Where Moz Pro wins

  • Domain Authority and Page Authority are Moz's own metrics and remain a widely used shorthand for comparing sites in link building and outreach.
  • Its own link index and Link Explorer give far more backlink data than SlapMyWeb's resold dataset.
  • Keyword Explorer and Rank Tracker are mature research and tracking tools, backed by the STAT rank-tracking platform Moz acquired in 2018.
  • Site Crawl handles multi-site campaigns at volume, with paid plans tracking from 3 up to 25 sites and crawling hundreds of thousands to millions of pages a month.
  • Two decades of SEO education, including Moz Academy and Whiteboard Friday, plus a free Moz Community account with limited access to MozBar, Keyword Explorer and Link Explorer.

We keep this section honest on purpose. Moz Pro is a good tool with real advantages — pick the one that fits the job in front of you.

The detail

How they differ
once you look closely

Moz Pro vs SlapMyWeb: a research suite and an audit tool

Moz has been part of SEO for about two decades, and Moz Pro reflects that breadth. It is a research suite: Keyword Explorer for finding terms, Link Explorer and Domain Authority for judging sites and backlinks, Rank Tracker for positions, and Site Crawl for technical issues across campaigns. Moz has been owned by Ziff Davis since 2021. SlapMyWeb is narrower and goes deeper in one place. Paste a URL and it runs 240+ checks scored into 8 pillars, then returns a plain-English verdict, a prioritized action plan and fix code for each issue. The difference matters when choosing. If your work is research-led, such as finding keywords, qualifying link prospects or reporting authority to a client, Moz is built for that. If your work is fixing websites, the audit is the product, and SlapMyWeb puts more of its effort there. People comparing Moz with suites like WebCEO are usually weighing that same trade between breadth and audit depth.

How the audits compare: Site Crawl versus 8 scored pillars

Moz Pro's Site Crawl is a solid campaign crawler. It surfaces the classic technical problems, such as broken links, redirect issues, duplicate content and missing metadata, across many pages and tracks them over time. SlapMyWeb's audit covers a wider range of what can be wrong with a page. Its 8 pillars are weighted Speed 20%, SEO 18%, Security 15%, Mobile 12%, Design 10%, Accessibility 10%, Best practices 8% and Content 7%, and behind them sit deep-audit modules for Core Web Vitals using PageSpeed Insights v5 and CrUX field data, Puppeteer-based rendering, structured data validation, hreflang, image and video SEO, crawl budget, WCAG 2.2 AA accessibility via axe-core, security and compliance, and tracking setup. The other practical difference is the output. Moz tells you what is wrong and where. SlapMyWeb adds generated fix code, blurred on Free and full from Pro, so the handoff to a developer is shorter.

Where Moz Pro is clearly stronger

On data, Moz is in a different class. It maintains its own link index, and Domain Authority remains one of the most quoted metrics in link building and outreach. SlapMyWeb has no authority metric of its own, and its backlink and keyword features resell DataForSEO data with a far smaller footprint than a dedicated suite. Moz's Keyword Explorer and Rank Tracker are mature tools, and its acquisition of STAT in 2018 gave it serious rank-tracking depth for larger operations. Moz also crawls at scale: paid plans track from 3 to 25 sites and crawl hundreds of thousands to millions of pages a month, while SlapMyWeb audits one site per scan and is not a crawler for 100,000-URL sites. Moz has added AI Visibility dashboards to its plans, and it backs everything with an education library in Moz Academy and Whiteboard Friday. For an SEO who lives in research data, those strengths are hard to replace.

Is there a Moz penalty checker, and what each tool can tell you

A common search is for a Moz penalty checker. Moz does not sell a dedicated penalty tool. What it does publish is a long-running history of Google algorithm updates, which many SEOs use to line up a traffic drop with a known update date. A manual penalty, which Google calls a manual action, is only confirmed inside your own Google Search Console account. SlapMyWeb cannot see that either: it is an outside-in audit and has no access to your Search Console data. What it can do is find the on-site causes that often sit behind a drop after an update, such as slow Core Web Vitals, thin or duplicate pages, broken structured data, security problems or pages that do not render without JavaScript. So the honest workflow is to check Search Console for manual actions, use an update timeline like Moz's to date the drop, and then audit the site to find what to fix.

The bottom line

Moz Pro and SlapMyWeb overlap on site auditing, keywords and rank tracking, but they lead with different things. Choose Moz Pro when research data is the job: you need Domain Authority, a deep link index, mature keyword and rank tools, and campaign crawls across several sites. It starts around ~$49/mo, with Standard around ~$79/mo on yearly billing and larger plans above that. Choose SlapMyWeb when fixing sites is the job: its audit covers speed, security, accessibility, rendering and structured data in one scan, adds generated fix code, and starts free at 10 scans a day, with Pro at $9/mo and Agency at $29/mo. SlapMyWeb launched in 2026, so it has neither Moz's history nor its data scale, and it does not claim to. The cheap test is to run a free scan on a site you already track in Moz and compare it with your latest Site Crawl. Whatever SlapMyWeb finds that Moz did not is the value of adding it.
