People looking for Ahrefs alternatives usually want a different balance of backlink intelligence, keyword research, rank tracking, and technical auditing. The products below do not all solve the same problem. Some combine several SEO workstreams, while others concentrate on link indexes, traffic modeling, keyword discovery, or desktop crawling.
The figures and plan references on this page were checked on July 31, 2026. Vendor databases change as crawlers revisit pages and pricing can vary by billing cycle, currency, tax, account limits, user seats, add-ons, or negotiated contracts. Published index size is therefore a dated reference rather than a direct measure of which product will match a particular workflow.
Product categories differ: Semrush and SE Ranking cover several SEO tasks in one account. Majestic centers its reporting on the link graph. Similarweb models traffic and market behavior. Mangools divides keyword, SERP, rank, link, and site research into connected tools. Screaming Frog SEO Spider crawls websites from a desktop application.
Ahrefs Alternatives Comparison Table
| Platform | Main Use | Primary Data Model | Included Work | Published Entry Reference |
|---|---|---|---|---|
| Ahrefs | SEO research across links, keywords, rankings, content, and audits | Proprietary web crawler, SERP databases, and estimated traffic models | Backlinks, keywords, site audit, rank tracking, competitive research | Starter $29/month; Lite $129/month |
| Semrush | SEO and wider competitive marketing research | Backlink crawler, SERP collection, third-party providers, and modeled traffic data | Keywords, links, audits, position tracking, competitor and advertising research | SEO plan $139/month; annual equivalent $117.33/month |
| SE Ranking | Project-based SEO management and reporting | Backlink and keyword databases combined with project crawls and tracking | Rank tracking, audits, competitor research, backlinks, reports, API allowances | Core €109/month; annual equivalent €87.20/month |
| Majestic | Backlink history and link-graph analysis | Fresh and Historic link indexes with Flow Metrics | Referring domains, link context, topical signals, link history, exports | Lite €46.99/month; annual equivalent €39.16/month |
| Similarweb | Traffic, audience, channel, and market benchmarking | First-party measurements, contributor data, public data, partnerships, and modeling | Traffic estimates, audience research, market comparison, search and referral analysis | Limited free data; business packages use trials or sales-assisted pricing |
| Mangools | Keyword, SERP, rank, backlink, and domain research in separate tools | Keyword and SERP datasets combined with link and site metrics | KWFinder, SERPChecker, SERPWatcher, LinkMiner, and SiteProfiler | Basic, Premium, and Agency subscriptions |
| Screaming Frog SEO Spider | Technical crawling and page-level inspection | Live crawl of a supplied website or URL list | Status codes, directives, metadata, duplicates, rendering, extraction, and integrations | Free to 500 URLs; paid licence €245/year |
The table compares operating models, not identical bundles. A desktop crawler can inspect a site in greater technical detail without offering a global backlink index. A traffic-intelligence platform can model audience behavior without serving as the main tool for daily rank tracking.
What Ahrefs Covers for SEO Teams
Ahrefs combines backlink research, keyword discovery, rank tracking, competitive analysis, content research, web analytics, and technical auditing. Its public Backlink Checker page states that the link index receives fresh data every 15 minutes and lists 493 billion pages, 500 million domains, and 35 trillion external backlinks in historical records. ✅[Source-1]
- Off-Page Research
- Backlinks, referring domains, anchors, link growth, lost links, competing pages, and proprietary rating metrics.
- Organic Research
- Keyword databases, SERP history, search intent, competing pages, content gaps, and estimated organic traffic.
- Monitoring
- Tracked keywords, alerts, project dashboards, reports, and changing search visibility.
- Technical Inspection
- Site Audit crawls, internal links, indexability, redirects, duplicate signals, performance data, and site structure.
The current pricing page separates a $29 monthly Starter product from the main Lite, Standard, Advanced, and Enterprise plans. Lite is listed at $129 per month and includes five unverified projects, 750 tracked keywords, 100,000 monthly crawl credits, six months of historical data, and one included user. Standard and Advanced raise project, history, tracking, crawl, and export limits. ✅[Source-2]
Comparable labels are not interchangeable. Domain Rating, Domain Trust, Trust Flow, Citation Flow, and other vendor scores use different indexes and formulas. They are most useful for comparisons inside the same platform and dataset.
How SEO Data Is Built Across Platforms
SEO reports combine several kinds of evidence. A crawler can record a page and its links directly. A rank tracker stores search-result positions for selected terms, locations, and devices. Search volume, traffic, and audience reports often add modeled estimates because no outside provider can see every search or every visit.
- Web crawlers discover pages and links, then process redirects, canonicals, duplicates, and repeated link observations into an index.
- SERP collection records results for chosen keywords, markets, devices, and dates to support ranking history and competitive research.
- Project crawls inspect a website supplied by the user and report technical conditions found during that crawl.
- First-party connections can add verified analytics or search-console records for a site the account controls.
- Modeled traffic data uses panels, partnerships, public information, and statistical methods to estimate visits, channels, and audience behavior.
- Vendor metrics summarize parts of a proprietary dataset. Scores from different products should not be treated as the same scale.
Freshness also has several meanings. A vendor may update its global link index throughout the day while updating tracked keywords daily or weekly. Historical access can refer to archived SERPs, old backlink observations, trend charts, or retained project data. Each limit should be checked separately.
All-in-One SEO Platforms
Semrush
Semrush combines keyword and domain research with backlink analysis, position tracking, site auditing, advertising research, traffic estimates, and reporting. This makes it relevant to teams that want SEO data beside paid-search and wider competitive information.
Semrush states that its backlink crawler scans about 10 billion pages per day and contributes to a database of more than 43 trillion backlinks. Its 2026 data page also lists 27.9 billion keywords, 808 million domains, 142 geographic databases, and a traffic panel built from more than 200 million anonymized users across over 190 countries and regions. ✅[Source-3]
- Suitable workflow: keyword research, competitor comparison, PPC research, link analysis, site projects, reporting, and search visibility monitoring.
- Data distinction: backlink information comes from its crawler, while traffic estimates use a panel and modeling process.
- Account planning: projects, tracked keywords, crawl capacity, historical access, report rows, and toolkits have separate limits.
The current SEO plan is listed at $139 per month or an annual equivalent of $117.33 per month. Semrush One plans add AI-search tracking and begin with Starter at $199 per month or an annual equivalent of $165.17. ✅[Source-4]
SE Ranking
SE Ranking organizes rank tracking, website audits, competitor research, backlink analysis, on-page checks, report building, and project management in one account. Its plan structure is useful to review when daily keyword tracking, client projects, manager seats, API allowances, and repeatable reports are part of the same workflow.
The public Domain Trust checker lists 2.9 trillion indexed backlinks, 357 million indexed domains, and about 6 billion pages crawled daily. The same page states that 58% of backlinks are refreshed within 90 days. It also describes Domain Trust and Page Trust as proprietary scores based on backlink and referring-domain signals. ✅[Source-5]
- Suitable workflow: tracked projects, daily position data, audits, client access, white-label reporting, and competitor monitoring.
- Account structure: plans set allowances for projects, manager seats, keywords, prompts, audit pages, and API credits.
- Data use: global research tools and project-specific monitoring sit in the same interface but use different limits.
SE Ranking currently lists Core at €109 per month or €87.20 per month with annual billing. It includes 10 projects, one manager seat, 2,000 tracked keywords, 250,000 monthly audit pages, and 25,000 API credits. Growth is listed at €235 per month or an annual equivalent of €188 and raises project, keyword, audit, seat, and API allowances. ✅[Source-6]
Backlink-First Alternatives
Majestic
Majestic is centered on a web-scale link map. Its product language includes Fresh Index, Historic Index, Trust Flow, Citation Flow, Topical Trust Flow, referring subnets, link context, backlink history, and network relationships.
The Fresh Index is the more frequently rebuilt dataset, while the Historic Index retains a longer view of discovered links. Majestic states that it aims to update the Fresh Index daily and the Historic Index about once a month. It also explains that an older backlink can reappear as newly found when it leaves the Fresh Index and is later rediscovered, because a crawler knows when it found a link rather than when the link was first published. ✅[Source-7]
For historical link work, Majestic Pro includes the Historic Index, backlink history, raw data exports, Flow Metric history, site comparisons, and Index Merger. Lite is more focused on current link checking through the Fresh Index. This separation makes the chosen plan relevant to the type of link history a team needs.
- Suitable workflow: backlink reviews, domain comparison, link prospect research, topical link analysis, and historical link changes.
- Metric handling: Trust Flow and Citation Flow are intended to be read together and should not be converted directly into another vendor’s authority score.
- Scope: the platform concentrates more of its interface on link relationships than on technical crawling or broad traffic-channel modeling.
Majestic lists Lite at €46.99 per month or an annual equivalent of €39.16. Pro is €94.99 monthly or an annual equivalent of €79.16 and adds the Historic Index, larger data allowances, exports, and comparison reports. API access is provided through a separate higher-tier plan. ✅[Source-8]
Traffic and Market Intelligence
Similarweb
Similarweb is oriented toward digital traffic, audience behavior, channel distribution, market comparison, search demand, referrals, advertising, and app intelligence. It can support SEO research, but its defining use is broader than backlink inspection or a project crawl.
Similarweb describes a mixed data process that includes direct measurements from website and app owners, anonymous contributor-network data, public sources, and partnerships. Those inputs are cleaned, combined, and modeled to estimate activity across websites and applications. Its public methodology page lists 10 billion digital signals collected daily, more than 100 million websites, over 4 million apps, and 10 years of historical data. ✅[Source-9]
- Suitable workflow: comparing traffic scale, acquisition channels, audience overlap, market share, referral sources, search demand, and competitor movement.
- Interpretation: external traffic figures are estimates and may differ from a site owner’s first-party analytics.
- SEO role: useful for market and channel context alongside a dedicated crawler, link index, or rank-tracking platform.
Similarweb provides limited public data and offers trials or self-service access for some users. Business and enterprise packages are tailored through sales, with features and pricing depending on the selected intelligence products, countries, historical depth, users, APIs, and exports. ✅[Source-10]
Keyword and SERP Research
Mangools
Mangools divides its SEO work across connected products rather than presenting every report inside one large project interface. KWFinder covers keyword discovery, SERPChecker examines result pages, SERPWatcher tracks positions, LinkMiner handles backlink research, and SiteProfiler summarizes domain-level data.
This structure can suit users who want direct access to a defined research task without building a large project dashboard first. Search limits, tracked keywords, backlink rows, keyword suggestions, simultaneous logins, and additional seats still need to be compared at the plan level.
- Suitable workflow: keyword discovery, local SERP review, position monitoring, backlink inspection, and basic site comparisons.
- Product structure: separate tools share one subscription and account.
- Selection point: check daily lookup allowances and tracking capacity against the number of sites and markets being researched.
The current pricing page offers Basic, Premium, and Agency subscriptions. Each includes keyword research, keyword suggestions, SERP analysis, rank tracking, backlinks, and site analysis, with higher plans providing larger allowances and support for added seats. ✅[Source-11]
Technical Crawlers
Screaming Frog SEO Spider
Screaming Frog SEO Spider is a desktop crawler that retrieves pages and reports what it finds on the supplied site. It is used for status codes, redirects, titles, descriptions, canonicals, directives, headings, internal links, hreflang, structured data, duplicate content, JavaScript rendering, custom extraction, and other page-level checks.
It does not serve the same role as a global backlink or keyword database. Instead, it can sit beside Ahrefs or another research platform when a team needs direct control over crawl configuration, authentication, rendering, extraction, segmentation, or local storage.
- Suitable workflow: technical audits, migrations, redirect checks, internal-link analysis, metadata review, structured-data inspection, and quality assurance.
- Data source: the live website, URL list, sitemap, or connected services selected for the crawl.
- Resource model: paid crawls are not given a fixed URL ceiling, but practical size depends on allocated memory and storage.
The free edition crawls up to 500 URLs. The paid version is listed at €245 per user per year and adds unlimited crawl size subject to machine resources, scheduling, saved crawls, JavaScript rendering, crawl comparison, custom extraction, integrations, and other advanced controls. ✅[Source-12]
Pricing and Quotas That Change the Comparison
The subscription price rarely describes the full amount of usable data. Two plans with similar monthly prices can differ in projects, seats, reports, retained history, API access, crawl capacity, tracked terms, and export rows.
| Limit | What It Controls | Why It Matters |
|---|---|---|
| Projects | How many sites can use saved dashboards, audits, alerts, or tracking. | A research tool may allow many domain lookups while limiting saved projects. |
| Tracked Keywords | The number of terms monitored on a schedule. | One keyword tracked across several locations or devices may consume more than one allowance. |
| Update Frequency | How often rankings, links, prompts, or audit data are refreshed. | Daily, weekly, and on-demand updates support different reporting cycles. |
| Historical Data | The period available for past SERPs, link records, traffic trends, or project history. | Higher tiers may be needed for year-over-year or pre-project comparisons. |
| Crawl Capacity | Pages allowed per month, per project, or per local crawl. | Large sites and repeated audits can use capacity faster than occasional research. |
| Rows and Exports | Results shown or downloaded from each report and across the billing period. | A large index has limited value when the selected plan exposes too few rows for the task. |
| Users and Seats | People allowed to use the account and their permissions. | Extra analysts, clients, or managers may add recurring cost. |
| API Access | Programmatic requests, credits, endpoints, and export automation. | API access may start on a higher tier or use a separate credit system. |
| Add-Ons | AI tracking, content tools, local data, advanced reports, or boosted projects. | An advertised base plan may not include every module shown across the product site. |
Matching the Product to the Work
- Broad SEO and marketing research: compare Semrush with Ahrefs when keyword, link, site, competitor, advertising, and traffic reports need to share one account.
- Project tracking and agency reports: compare SE Ranking’s projects, seats, tracked terms, report tools, and API credits with the account’s actual client load.
- Historical backlink research: review Majestic Pro because Historic Index access and link-history exports are tied to that tier.
- Traffic and audience benchmarking: use Similarweb where modeled visits, channels, market movement, and audience information are the central requirement.
- Focused keyword and SERP work: review Mangools when a set of connected, task-specific tools matches the required lookup volume.
- Direct technical crawling: use Screaming Frog SEO Spider beside a research database when page retrieval, rendering, extraction, or migration testing is the main task.
Test with the same sample. Run the same domain, keyword set, backlink target, and site section through shortlisted products. Compare the rows returned, update dates, export structure, filters, and time needed to reach the report—not only the headline database figures.
Frequently Asked Questions
Which Ahrefs Alternative Covers the Widest Range of Marketing Data?
Semrush covers SEO research together with advertising, traffic, market, content, local, and AI-search products. The exact modules included depend on the chosen plan and toolkits, so the account should be compared by included projects, limits, and add-ons rather than by the platform name alone.
Which Alternative Is Centered on Backlink History?
Majestic is designed around its link map, Fresh Index, Historic Index, and Flow Metrics. Historic Index access is included with Pro rather than Lite. Ahrefs, Semrush, and SE Ranking also provide backlink history, but their accounts divide attention across more SEO modules.
Can Similarweb Replace Ahrefs for Every SEO Task?
Similarweb is mainly useful for traffic, audience, channel, search-demand, and market comparison. It can add context to SEO research, but teams that need detailed link history, daily rank tracking, or configurable technical crawls may still use a dedicated product for those tasks.
Is Screaming Frog SEO Spider an Ahrefs Replacement?
It replaces the technical-crawl portion of the workflow rather than the global keyword and backlink databases. It retrieves a supplied site directly and offers detailed crawl controls, making it a companion or focused substitute when technical inspection is the main requirement.
Why Do Backlink Counts Differ Between SEO Platforms?
Each provider crawls a different portion of the web on its own schedule. Vendors also differ in URL normalization, duplicate handling, canonical processing, redirect treatment, retained history, and the definition of a live or lost link. Counts should be compared with matching target settings and dates.
Are Authority Scores Comparable Across Vendors?
Not directly. Domain Rating, Domain Trust, Trust Flow, Citation Flow, and related scores are calculated from different datasets and formulas. Use one metric to compare similar targets inside the same platform and record the date of the measurement.
Which Limits Matter Most for Rank Tracking?
Check the number of tracked keywords, update frequency, supported search engines, devices, countries, locations, retained history, competitor slots, and the way one keyword is counted across several tracking settings.
What Should Be Checked During a Trial?
Use real domains and a representative keyword set. Review data freshness, report depth, export rows, filters, technical crawl controls, user permissions, scheduled reports, and the cost of the tier that contains the required limits.
