How we make this list: we compare pricing pages, product documentation and public user reviews. Ratings come from G2, Capterra or Trustpilot, with the date we checked them.
Key takeaways
- Page One Power and Siege Media suit businesses that want editorial links earned through content and manual outreach.
- uSERP and Editorial.Link are strong for startups and SaaS companies that need links from relevant industry sites.
- FATJOE and The HOTH work for agencies and site owners who want to order links and services on demand.
- Link building pricing is almost always custom, so expect a quote based on your niche, targets and link volume.
- Avoid any agency that guarantees a specific number of links for a flat fee without showing you the sites first.
Link building remains one of the most effective ways to improve search rankings, but it is also the easiest service to buy badly. A good agency earns links from real sites with real audiences, through outreach, content and digital PR. A poor one places links on thin sites that exist only to sell links, which can hurt more than help. The companies below are established names with public client work, transparent methods and reporting you can check.
Pricing in this field is almost always custom. Agencies quote by niche difficulty, the authority of target sites and the number of links per month. The comparison table therefore marks prices as "See website" and you should expect a proposal call before any firm number appears. Ask every agency on your shortlist for sample links, a list of sites they have placed on, and a sample report before signing.

The best link building companies

Page One Power has specialised in link building since 2010, and its method is deliberately manual. Outreach specialists contact site owners by hand, pitch resource pages and broken link replacements, and build links that look like the natural editorial links search engines reward. The agency publishes case studies and method explainers, which makes its process easier to audit than most competitors.
The downside is patience. Manual outreach does not produce links overnight, and monthly minimums suit businesses with an ongoing SEO budget rather than a one-off purchase. For companies that want links they can show a client or a boss without embarrassment, Page One Power is a safe first call.
What we like- Long track record in manual, white-hat outreach
- Resource page and broken link building expertise
- Detailed monthly reporting
Watch out for- Custom pricing means no public entry point
- Campaigns take time to show results

Siege Media pairs link building with content creation. Its teams research topics with ranking and link potential, produce data-driven articles, graphics and tools, then promote them to journalists and bloggers. Links earned this way tend to come from stronger sites and keep arriving after the campaign ends, since the content stays live and keeps getting cited.
That model costs more than pure outreach. Businesses need budget for both content production and promotion, and results build over months rather than weeks. For companies that want links plus content assets they own, Siege Media is one of the strongest agencies in this space.
What we like- Content strategy and design built in
- Strong digital PR and passive link earning
- Well documented case studies
Watch out for- Premium pricing
- Content-led campaigns need a larger budget

uSERP focuses on fast-growing companies, especially SaaS and fintech, and its outreach targets sites those audiences actually read. The agency offers performance-based arrangements on some campaigns, so part of the fee ties to links actually placed. Clients see the sites before links go live, which avoids the mystery placements that plague cheaper services.
The niche focus cuts both ways. A local trades business or a pure ecommerce store may find the outreach list less relevant than a generalist agency's. Minimum monthly spends also put it out of reach for very small sites. For a SaaS company that needs relevant, high-authority links, uSERP is a natural shortlist name.
What we like- Focus on SaaS, fintech and startup niches
- Performance-based options
- Transparent link placements
Watch out for- Niche focus means less fit for local or ecommerce-only businesses
- Minimum spends apply

Editorial.Link sells editorial links from a large network of sites, with per-link pricing that suits buyers who want a set number of placements. Turnaround is faster than a traditional outreach campaign, and buyers can review target sites before paying. The service works well for site owners who already have a content and on-page strategy and just need links to support it.
Per-link buying carries a quality risk. The buyer must check each site's relevance and traffic rather than trusting a domain authority score alone. Editorial.Link is also lighter on strategy than Siege Media or Page One Power. For buyers who know what they want and can vet sites, it is an efficient option.
What we like- Large network of editorial sites
- Per-link pricing available
- Fast turnaround on many orders
Watch out for- Per-link buying needs careful quality checks
- Less strategy depth than full-service agencies

LinkGraph is a full-service SEO agency with a strong link building arm, and its data-led approach sets it apart. Outreach targets are chosen from search and traffic data rather than generic authority metrics, and clients get dashboards that show placements, anchor text and ranking movement together. The agency also handles technical SEO, so link campaigns are not undermined by site problems.
That breadth costs more than a link-only vendor. Businesses that only want links may find the minimum engagement higher than expected. For companies that want links as part of a wider SEO program, LinkGraph gives a joined-up service.
What we like- Combines technical SEO with link building
- Data-led outreach targeting
- Clear dashboards
Watch out for- Full-service scope means higher minimums
- Link building alone is not the cheapest entry

Stellar SEO is a boutique outreach agency known for clear reporting. Monthly reports show live links, the sites they sit on and the anchor text used, so clients can verify every placement. Outreach targets real blogs, news sites and industry publications rather than private blog networks. Campaign sizes are flexible, which helps smaller businesses that cannot commit to a large monthly retainer.
Being smaller has a cost. Capacity is limited, and very competitive niches may face waiting lists. For a business that wants to see exactly what it paid for each month, Stellar SEO's transparency is a genuine advantage.
What we like- Transparent monthly reports with live links
- Outreach to real blogs and news sites
- Flexible campaign sizes
Watch out for- Smaller agency, so capacity is limited
- Pricing varies by niche difficulty

FATJOE sells link building and content services as products you can order without a retainer. Blogger outreach, niche edits, press releases and infographic outreach are listed with descriptions and turnaround times, and a dashboard tracks orders. Agencies use FATJOE to fulfil client work, and site owners use it for one-off campaigns.
The self-serve model means strategy is your job. There is no dedicated strategist shaping a campaign around your site, and lower-priced tiers place on weaker sites. For buyers who know their niche and want to order specific services on demand, FATJOE is convenient and predictable.
What we like- Order links and content services without a retainer
- Clear product catalogue
- Popular with agencies reselling services
Watch out for- Self-serve model means less strategy
- Quality varies by product tier

The HOTH offers one of the widest catalogues in link building, from guest posts and niche edits to fully managed SEO campaigns. Self-serve buyers pick products and quantities, while managed clients get a strategist and a monthly plan. The platform is popular with agencies that need reliable fulfilment for many clients at once.
Breadth brings uneven quality. Some products place on strong sites, while others are weaker, so buyers should vet placements and start small. Managed plans solve that problem but cost more. For agencies and site owners who want one supplier for many link products, The HOTH is a practical choice.
What we like- Wide product range from guest posts to managed SEO
- Managed campaigns available
- Large agency user base
Watch out for- Product quality varies across the catalogue
- Managed plans cost more than self-serve
How we chose
We compared agencies on their published methods, client case studies, reporting samples and public reviews from SEOs and site owners. We favoured agencies that show real placements, explain their outreach method and report live links clients can verify. Prices were marked "See website" because link building quotes depend on niche, target authority and volume, and a printed starting price would mislead. We did not claim hands-on testing.
Vetting an agency before you pay
Ask for five sample links placed in the last three months, then check those sites yourself. Look for real traffic, real authors and content that is not obviously written to host links. Ask whether links are marked sponsored or nofollow, since that changes their SEO value. Confirm who writes the outreach emails and whether you approve target sites before placement.
Also check the contract. Good agencies work month to month or with short terms after an initial period, while long lock-ins with vague deliverables are a warning sign. Finally, agree on reporting: live link URLs, anchor text, placement dates and traffic data for target sites. If an agency will not show you where links go, do not sign.
Frequently asked questions
How much does link building cost?
Most agencies quote monthly retainers that depend on niche difficulty, target site authority and link volume. Small campaigns often start in the low four figures per month in dollars, while competitive niches cost more. Per-link services publish product prices, but quality varies by tier. Always get a written proposal before committing.
How long does link building take to work?
Outreach campaigns usually need two to three months before placements appear at volume, and ranking effects often follow over three to six months. Content-led campaigns take longer but tend to earn links that keep arriving. Any agency promising first-page rankings in weeks should be treated with suspicion.
Are paid links against Google's rules?
Google's spam policies discourage buying links intended to manipulate rankings. Reputable agencies describe their work as outreach and editorial placement, where site owners choose to link because content is useful. Links that are clearly paid and undisclosed carry risk, so ask how placements are earned and disclosed.
What is the difference between guest posts and niche edits?
A guest post is a new article written for a site that includes a link back to your page. A niche edit adds a link to an existing article on a site. Guest posts give more control over context, while niche edits can be faster and sit on pages that already rank. Good campaigns use both where appropriate.
Should I buy links or earn them myself?
Doing outreach yourself works if you have time and a good content asset, but it is slow and response rates are low. Agencies bring existing relationships and dedicated staff, which speeds placement. Many businesses mix both: an agency for scale and in-house outreach for their most important industry sites.
How do I check the quality of a link?
Check the linking site's organic traffic, whether it publishes real content from named authors, and whether the link sits in relevant editorial content rather than a sidebar or footer. Domain authority scores alone are a weak check, since they can be inflated. Relevance to your topic matters as much as authority.
