Link building software splits into three jobs: tracking the backlinks you already have, finding new sites worth targeting, and automating the outreach that earns a link. Backlink monitoring tools like SEOptimer and Linkody handle the first job, prospecting tools like BuzzSumo and SEO PowerSuite's LinkAssistant handle the second, and outreach platforms like Postaga and Snov.io handle the third.
This is a Rankite buyer's guide, August 2026, built from each vendor's own pricing and feature pages rather than paid trials of every platform. If you want an all-in-one backlink research and outreach platform like Ahrefs, Semrush, or Pitchbox, see our link building tools roundup instead. This guide covers the software teams usually add around a platform like that: dedicated monitoring, prospecting, and outreach tools most sites reach for once a single subscription stops covering everything they need.
What is link building software?
Link building software is any tool built around one of three jobs: tracking backlinks you already have, finding new sites worth targeting for a link, or automating the outreach that asks for one. On this list, SEOptimer and Linkody handle monitoring, BuzzSumo and SEO PowerSuite's LinkAssistant handle prospecting, and Postaga and Snov.io handle outreach automation. None of them replace genuine outreach or content worth linking to; they remove the manual tracking and admin that surrounds it.
The best link building software by category
Rather than one ranked "best overall" list, the six tools below are grouped by the job they actually do. Pick from the category that matches what is currently eating the most manual time, then add a second category once that first job is running smoothly.
Backlink monitoring software
Monitoring tools do not find new links, they watch the ones you have and tell you the moment something changes, whether that is a link going live, a link disappearing, or an anchor text getting edited.
SEOptimer (formerly Monitor Backlinks)
Monitor Backlinks ran as a standalone backlink discovery and tracking tool from 2012 until SEOptimer acquired it in August 2023 and folded its monitoring engine into the wider SEOptimer platform. The combined product still tracks new, lost, and changed backlinks in one dashboard, recording anchor text, link type, and referring domain for every placement it finds. Pricing on SEOptimer's own site runs from the $29/month DIY SEO plan up to $59/month for the White Label & Embedding tier that adds branded client reports.
Best for: teams that want backlink monitoring folded into a broader SEO reporting subscription. Standout feature: automated new, lost, and changed link alerts in one dashboard. Pricing: $29 to $59/month (seoptimer.com/pricing).
Linkody
Linkody is a narrower, cheaper alternative built purely around link tracking rather than a full SEO suite. Its Toxic Score flags backlinks that look spammy or low-quality, and it can generate a disavow file straight from the flagged list instead of making you build one by hand. Plans start at the Webmaster tier, $14.90/month billed monthly or $11.20/month billed annually, and scale up through Advanced, Pro, Agency, and Agency XL at $153.90/month for the largest limits, according to Linkody's own pricing page.
Best for: budget-conscious sites and agencies that only need dedicated link tracking, not a full research platform. Standout feature: Toxic Score with one-click disavow file export. Pricing: $14.90 to $153.90/month.
Prospecting and research software
Prospecting tools help you find sites worth targeting before you ever send an email, either by surfacing who is already writing about your topic or by mining your own site and competitors for opportunities.
BuzzSumo
BuzzSumo was built for content and PR research, and that shows in how it fits link prospecting: its Question Analyzer surfaces what people are actually asking about a topic, and its Media Database finds journalists and publications already covering your space, both of which double as a prospect list for outreach. Pricing starts at $199/month for the single-user Content Creation plan and climbs to $999/month for the 30-seat Enterprise tier, per BuzzSumo's own pricing page.
Best for: content and PR-style link prospecting through existing coverage and journalist contacts. Standout feature: Media Database plus Question Analyzer for PR-angle link pitches. Pricing: $199 to $999/month (buzzsumo.com/pricing).
SEO PowerSuite LinkAssistant
LinkAssistant is the odd one out here: a desktop application rather than a browser-based subscription, sold as one of four tools in the SEO PowerSuite bundle alongside Rank Tracker, WebSite Auditor, and SEO SpyGlass. It searches for prospects using built-in search-based methods and lets you manage outreach status locally, with no monthly bill once you own a license. Link-Assistant.com's own pricing lists Professional at $149/year and Enterprise at $349/year, with multi-year prepayment discounts available.
Best for: teams that would rather pay an annual license than a recurring monthly subscription. Standout feature: runs locally with unlimited link-building projects, no per-seat pricing. Pricing: $149 to $349/year (link-assistant.com).
Outreach automation software
Outreach tools pick up where prospecting leaves off: finding a contact's email, sending a personalized pitch, and tracking who opened, replied, or needs a follow-up.
Postaga
Postaga is built specifically around link building campaign types, guest posts, resource page mentions, roundups, and similar formats, and pairs each one with its own Backlink Opportunity Finder that searches for sites already running that kind of content. Automatic personalization adjusts each email based on the target page rather than sending one template to everyone. Postaga's own pricing page lists the Pro plan at $84/month billed annually ($99/month month-to-month) for 2,000 contacts, and Agency at $250/month annually ($299/month month-to-month) for 15,000 contacts.
Best for: teams that want outreach tooling built specifically around link building campaign types, not general sales email. Standout feature: Backlink Opportunity Finder mapped directly to campaign type. Pricing: $84 to $250/month, annual billing (postaga.com/pricing).
Snov.io
Snov.io is a broader B2B email-finding and outreach platform, not built specifically for link building, but its email finder, verifier, and drip-campaign tools work just as well for backlink outreach as they do for sales. Every plan includes unlimited seats, so a five-person link building team pays the same subscription as a solo operator. Snov.io publishes a free tier with 50 credits and 100 recipients, then Starter at $39/month, Pro S at $99/month, Pro M at $189/month, Pro L at $369/month, and Ultra from $738/month.
Best for: teams that already use one platform for both sales and link outreach and want a single credit system. Standout feature: unlimited seats per plan plus a built-in verifier and email warmup. Pricing: free to $738+/month (snov.io/pricing).

How much does link building software cost?
Prices on this list run from Linkody's $14.90/month Webmaster plan to BuzzSumo's $999/month Enterprise tier. Backlink monitoring software is consistently the cheapest category, starting around $15 to $29/month because it only tracks existing links rather than searching for new ones or running email campaigns. Prospecting and outreach platforms cost more because they bundle a contact database, search index, or campaign infrastructure behind the subscription, and that typically pushes the entry price to somewhere between $84 and $199/month. LinkAssistant is the exception on price structure rather than amount: it charges an annual license fee instead of a monthly one, which suits teams who would rather own the tool than rent it. For the sourced pricing behind an outreach or research service instead of software, our link building services page lists what a done-for-you program costs, and our free backlink checker tools roundup covers what you can check without paying for anything at all.
Do you need more than one type of link building software?
Most active link builders end up running at least two categories at once: a monitoring tool to confirm links stay live, and either a prospecting tool or an outreach platform to keep finding and pursuing new ones. A single-person blog can often get by on one monitoring tool plus manual outreach; an agency running campaigns for several clients typically needs monitoring, prospecting, and outreach all running in parallel, usually from different vendors rather than one platform that does everything adequately.
Once you know your own numbers, our backlink management guide covers what to actually do with the links these tools surface, and our step-by-step guide to building backlinks walks through the outreach process these platforms are built to speed up.
What is the best link building software for small businesses vs. agencies?
Small businesses and solo sites are usually better served by Linkody's $14.90/month Webmaster plan or Snov.io's free tier, since neither requires a dedicated outreach hire to justify the cost. Agencies running multiple client accounts tend to need the white-label reporting and higher seat counts in SEOptimer's White Label tiers, BuzzSumo's PR & Comms or Suite plans, or Postaga's Agency plan, all of which are priced and built for managing several campaigns under one login rather than a single site.
How we picked these tools
This is a Rankite buyer's guide, August 2026, built from each vendor's own pricing and feature pages, cross-checked against independent write-ups and Capterra listings where pricing needed a second source, rather than paid trials of every platform ourselves. We grouped tools by the job they primarily do instead of ranking them on one scale, because a $999/month PR research platform and a $14.90/month link tracker are not actually competing for the same buyer. Where a tool's history mattered, such as Monitor Backlinks' 2023 acquisition by SEOptimer, we noted it rather than treating the two brands as unrelated.
If you would rather hand outreach off entirely than manage software and campaigns yourself, our link building services run the research, outreach, and vetting these platforms automate, backed by results like Swordfish AI's 400% organic revenue growth and LiveHelpNow's 3,000 extra monthly visits, also cited in Google AI Overviews. For the DIY route, our guide to outsourcing link building covers when hiring out makes more sense than adding another subscription, and our link building tools comparison covers the all-in-one research and outreach platforms this guide deliberately left out.
Frequently asked questions
What is link building software? Link building software is any tool that helps with one of three jobs: tracking the backlinks you already have, finding new sites that might link to you, or automating the outreach emails that ask for a link. SEOptimer and Linkody handle monitoring, BuzzSumo and LinkAssistant handle prospecting, and Postaga and Snov.io handle outreach. Most teams end up using at least two categories together.
What are the different types of link building software? Three main types exist: backlink monitoring tools like SEOptimer and Linkody that alert you when links appear or disappear, prospecting and research tools like BuzzSumo and SEO PowerSuite's LinkAssistant that surface sites worth targeting, and outreach automation tools like Postaga and Snov.io that send and track the emails asking for a link.
How much does link building software cost? Prices on this list run from Linkody's $14.90 a month Webmaster plan to BuzzSumo's $999 a month Enterprise tier. Backlink monitoring tools are the cheapest category, starting around $15 to $29 a month, while outreach and prospecting platforms with built-in contact databases typically start between $84 and $199 a month.
Is there free link building software? Snov.io offers a genuine free tier with 50 credits and 100 recipients a month, and SEOptimer, Linkody, Postaga, and LinkAssistant all offer free trials rather than permanent free plans. Google's own search operators remain a free way to find link prospects manually, without any software at all.
What is the difference between link building software and a link building service? Software gives you the tools to find prospects and send outreach yourself, and you pay the subscription whether or not a link lands. A link building service, like Rankite's link building services, runs the outreach, vetting, and placement for you and is judged on links actually delivered, not seats or credits.
Do I need backlink monitoring software if I already use Ahrefs or Semrush? Not necessarily. Ahrefs and Semrush both include backlink tracking inside a broader research subscription, so a dedicated monitoring tool like Linkody or SEOptimer mostly earns its keep if you want automated lost-link alerts without paying for a full research platform, or if you are monitoring many client sites at once.
What is the best link building software for small businesses? Linkody's Webmaster plan at $14.90 a month and Snov.io's free tier or $39 a month Starter plan both fit a small site's budget and link volume without needing a dedicated outreach team behind them.
What is the best link building software for agencies? BuzzSumo's PR & Comms and Suite plans, Postaga's Agency plan, and SEOptimer's White Label tiers are all built to manage multiple client accounts under one login, with the white-label reporting that agency work usually needs.
Can link building software build links automatically? No. Every tool on this list finds prospects, tracks results, or sends emails, but none of them can make a webmaster agree to link to you. A genuine reason to link, whether that is useful content or a real relationship, still has to come from your site.
Whichever category you start with, the software only speeds up research, tracking, and admin. If you would rather have that work handled for you, get in touch and we will show you what a link building program built around your site would actually look like.
