SEO platform for backlink research, keyword data and site audits

About Ahrefs

## What is Ahrefs? Ahrefs is an SEO platform best known for its backlink index and keyword research tools. It runs its own web crawler, AhrefsBot, and says it has been crawling the web for 15 years. According to its about page, the index holds about 3 trillion external backlinks and 28 trillion internal backlinks. The company is based in Singapore, describes itself as bootstrapped, and lists a team of around 150 people across 27 locations. For NCF readers, Ahrefs is the tool you open when you want to know why a competitor ranks, which keywords in a niche are worth chasing, or what is broken on your own site. It has grown from a backlink checker into a broader search platform that now tracks how brands show up in AI answers as well as in Google results. It is also one of the more expensive tools in this directory, so it pays to know exactly what you need before subscribing. ## Key features **Site Explorer.** Enter any domain or URL and see its backlinks, referring domains, organic keywords, estimated traffic and top pages. This is the fastest way to reverse-engineer a competitor's SEO. For a founder launching a SaaS product or template shop, seeing which pages bring a rival the most search traffic is often more useful than any keyword list. **Keywords Explorer.** Search volume, keyword difficulty, click estimates and related terms across many countries. You can filter for questions, low-difficulty terms or a parent topic, which helps when planning content clusters such as tool pages, comparison posts or templates. **Site Audit.** A crawler that checks your own site for technical problems: broken links, redirect chains, missing meta tags, slow pages and duplicate content. Useful for no-code sites built on Webflow, Framer or WordPress, where a small template issue can repeat across hundreds of pages. **Rank Tracker.** Tracks positions for a set list of keywords over time, with competitor comparisons. The number of tracked keywords depends on your plan, from 750 on Lite to 5,000 on Advanced. **Brand Radar and AI visibility.** Newer tools that track how often your brand appears in AI assistants and search features. Paid plans include a set number of AI prompt checks, and the full Brand Radar AI is a separate add-on starting at $199 a month. ## Best for Ahrefs suits people for whom organic search is a main growth channel and who will log in every week. That includes: - Agencies running SEO or content for several clients, who can spread the cost across retainers. - Content-led founders building directories, marketplaces, template stores or SaaS products that depend on search traffic. - Marketers doing competitor research, link building or content planning who need reliable backlink data. It is a weaker fit for a solo builder who checks SEO once a month. The free tier or a cheaper tool will cover occasional checks, and the Starter plan is a lighter option for basic keyword and competitor lookups. ## Pricing Ahrefs lists these monthly prices on its pricing page: - **Starter:** $29/month, aimed at seeing what people search for and comparing competitors. - **Lite:** $129/month. 5 unverified projects, 750 tracked keywords, 1 user, 6 months of history. - **Standard:** $249/month. 20 projects, 2,000 tracked keywords, 2 years of history. - **Advanced:** $449/month. 50 projects, 5,000 tracked keywords, 5 years of history. - **Enterprise:** $1,499/month with an annual commitment. Adds API access and SSO. Extra users cost $40 to $100 a month each depending on the plan. Annual billing saves up to 17%. Ahrefs Free gives website owners limited access to Site Explorer and Site Audit. ## Pros and cons **Pros** - One of the largest backlink indexes available, built on its own crawler. - Clean, fast interface that is easier to learn than most SEO suites. - Strong competitor research: top pages, content gaps and link sources in a few clicks. - A free option for site owners to audit their own site. - Now covers AI search visibility alongside Google. **Cons** - Expensive. Serious use starts at $129 a month, before extra users. - Every plan includes one user and charges for more seats, which adds up for small teams. - Add-ons like Brand Radar AI and Report Builder push the total higher. - Traffic and volume numbers are estimates and can differ from your real Search Console data. - Overkill for builders who only need occasional keyword checks. ## Verdict Ahrefs is worth it if search is how you grow and you will use it weekly. Agencies and content-led founders get the most out of it, and its backlink data and competitor views are hard to beat. If you are early, watching your budget or only need to check a few keywords, start with Ahrefs Free and Google Search Console, then upgrade once SEO is a proven channel. Watch the extras: seats and add-ons can push the bill well past the headline price.
