The appeal of cheap guest posts is obvious. You get a link on a third-party website, the site looks like a real editorial publication, and you pay a fraction of what premium link building services charge. The problem is that the gap between what cheap guest posts appear to deliver and what they actually deliver for rankings is wide enough to make them one of the most consistently disappointing link types in SEO. This guide explains exactly what you get when you buy guest posts cheap, where the quality floor sits for a guest post that actually moves rankings, how cheap guest posts compare to PBN links at equivalent price points, and when paying significantly more for a guest post is genuinely justified.
What Cheap Guest Posts Actually Are
Most guest posts sold in the £20–£60 price range are not placed on genuine editorial websites with real audiences. They are placed on one of two types of sites:
Type 1 — Personal blogs that accept any content for payment. These are websites that were once genuine content sites but have become essentially monetised link farms. They accept guest post submissions from anyone willing to pay, publish them without meaningful editorial review, and earn income from the volume of placements rather than the quality of content. Their organic traffic was once real but has often declined significantly as Google has downgraded their quality signals.
Type 2 — Purpose-built guest post sites. These sites were created specifically to sell guest post placements. They may have impressive-looking designs and plausible content, but they have never had a genuine editorial audience. Their DR may look reasonable due to link exchanges with similar sites, but their organic traffic is near-zero and Google quality systems assess them accordingly.
Neither type delivers the authority that genuine editorial coverage provides. The link is technically live and indexed. But the authority transfer is substantially lower than the domain metrics suggest, and in some cases the association with obvious link farm sites creates negative rather than neutral signals.
The True Cost-Per-Impact of Cheap Guest Posts
Evaluating cheap guest posts purely on list price misses the most important variable: cost per unit of ranking improvement. A £40 guest post that delivers zero measurable ranking impact has an infinite cost-per-improvement. A £80 PBN link on a maintained domain with genuine traffic that moves your target keyword three positions has a calculable, defensible cost-per-improvement.
| Price Point | Typical Guest Post Quality | Typical PBN Link Quality | Better Value |
|---|---|---|---|
| £20–£40 | DR 8–15, zero traffic, link farm | DR 15–22, minimal traffic, maintained domain | PBN link — more reliable authority |
| £40–£80 | DR 12–22, some traffic, borderline editorial | DR 22–32, some traffic, genuine content history | PBN link — better metrics at same price |
| £80–£150 | DR 20–35, moderate traffic, genuine sites accessible | DR 30–42, 50–200 monthly visits, strong domains | Comparable — depends on niche and anchor needs |
| £150–£350 | DR 35–55, real editorial traffic, credible publications | DR 40–55, consistent traffic, premium network | Guest post for YMYL/credibility; PBN for control |
| £350+ | DR 50+, national publications, genuine editorial | DR 50+, high-traffic network domains | Guest post for brand authority; PBN for scale |
The pattern is consistent: below £80, PBN links from quality networks deliver better cost-per-ranking-improvement than cheap guest posts in almost every case. Above £150, genuine editorial guest posts begin competing on quality, though PBN links retain the advantage on anchor text control, topical precision, and availability across restricted niches.
The Minimum Quality Threshold for a Guest Post Worth Buying
If you are going to buy guest posts, here is the minimum viable quality threshold below which the investment is unlikely to deliver meaningful ranking impact:
Domain DR 20 or above (Ahrefs). Below DR 20, the domain backlink profile is too weak to pass meaningful authority to your money site through a single guest post placement. DR 20 is a floor, not a target — aim for DR 25 or above for mid-tier campaigns.
Measurable organic traffic. Any confirmed organic traffic in Ahrefs or Semrush — even 50 to 100 monthly visits — confirms Google is actively ranking the domain. Zero traffic means the domain has not demonstrated editorial quality sufficient for Google to rank it. A guest post link from a domain Google does not rank is passing authority through a domain Google does not particularly trust.
Human-written content of at least 500 words. AI-generated or spun content of 200 to 300 words is insufficient context for Google quality systems to evaluate the link as a genuine editorial endorsement. The article surrounding your link needs to be substantive enough to pass a basic quality review.
Consistent publishing history of 12 months or more. A site that has been publishing content regularly for at least a year has a track record Google can evaluate. Sites created recently with rapid content volume increases are flagged more aggressively by quality systems.
Topical relevance to your money site. A guest post on a site covering topics unrelated to your money site passes authority through a link that lacks topical relevance signals. Even at adequate DR levels, relevance matters — a link from a cooking blog to a financial services site passes less targeted authority than a link from a finance-adjacent site.
Red Flags That Identify Low-Quality Guest Post Services
Guaranteed same-day or 24-hour placement. No genuine editorial review process operates at this speed. Same-day placement means your article is published automatically without any human quality control. The site is accepting content on a volume basis, not an editorial basis.
DA quoted without tool attribution. Sellers who quote “DA40+” without specifying whether this is Moz DA, Ahrefs DR, or something else are using unverifiable metric language by design. Always ask which tool and verify independently. For more on this see our guide on what high DA really means.
Packages of 10+ guest posts for under £100 total. At £8–£10 per placement, the sites receiving your content are either link farms or purpose-built placement sites with no genuine editorial standards. No legitimate editorial site accepts guest posts at this price point.
Site has hundreds of outbound links per page. Open the article page and count the outbound links. Pages with 50+ external links are distributing their PageRank across a huge number of destinations, meaning each individual link — including yours — receives a fraction of what it would on a page with fewer outbound links.
Content is clearly AI-generated or templated. If the surrounding article reads as generated rather than written, Google content quality systems evaluate it accordingly. Your link sits inside content flagged as low-quality, which affects how the link signal is processed.
No editorial guidelines or review process mentioned. Legitimate editorial sites describe their submission standards. Sites that say “submit any article and we will publish” have no editorial standards by definition.
Cheap Guest Posts vs PBN Links: The Direct Comparison
For buyers choosing between cheap guest posts and PBN links at equivalent budget levels, the comparison is generally straightforward:
At £30–£60
A cheap guest post at this price typically delivers a link on a DR 10–18 site with minimal or zero organic traffic, thin content, and uncertain longevity. A quality PBN link at the same price delivers a placement on a maintained domain with DR 20–30, genuine content history, and independent hosting infrastructure. The PBN link is almost always the better investment at this price point for ranking purposes.
The only exception is when the cheap guest post site is in a highly specific niche that exactly matches your money site topic — in that case, the topical relevance may compensate for lower raw authority. Verify this by checking whether the site has organic traffic for relevant topic keywords before purchasing.
At £70–£120
At this price range, quality diverges. You can access guest posts on sites with genuine DR 20–30 and real editorial audiences — and you can access PBN links on domains with DR 30–42 and consistent traffic. Both can deliver meaningful ranking impact. The choice depends on your specific campaign needs: if anchor text control and topical precision matter, PBN links win. If editorial credibility and content depth around the link matter, a quality guest post at this price is justified.
For a detailed framework on making this decision see our niche edit vs guest post vs PBN comparison guide.
At £150+
At premium price points, genuine editorial guest posts on DR 40+ sites with real audiences begin justifying their premium. The editorial credibility signal — a real publication choosing to publish your content — contributes to brand authority and E-E-A-T evaluation in ways that even quality PBN links cannot replicate. For YMYL niches (finance, health, legal), medical review sites, and brand-sensitive campaigns, this premium is often worthwhile. For volume-driven affiliate and e-commerce campaigns where topical authority and anchor precision matter more, PBN links at the same budget achieve more placements at comparable or higher individual domain quality.
When Paying More for Guest Posts Is Genuinely Justified
YMYL niches requiring E-E-A-T signals. Finance, health, legal, and medical sites are evaluated under Google YMYL (Your Money or Your Life) guidelines where E-E-A-T — Experience, Expertise, Authoritativeness, Trustworthiness — is assessed carefully. A guest post by-lined to a named expert on a credible industry publication contributes to E-E-A-T in a way no PBN link can replicate. For these niches, investing £200–£500 in genuine editorial placements is justified and often necessary.
Building topline brand authority. If your SEO goal includes not just rankings but brand recognition and direct referral traffic, editorial guest posts in publications your target audience actually reads deliver both. A link from an industry publication that your prospects read regularly has commercial value beyond pure link equity.
SaaS and B2B technology niches. In B2B software and technology niches, links from industry-relevant publications carry significant weight for both direct referral traffic and SERP authority. Decision-makers in these niches actively read industry publications, making editorial guest post placements commercially valuable beyond their link equity contribution.
As the top layer of a mixed link profile. Even campaigns primarily built on quality PBN links benefit from having one or two genuine editorial guest posts at the top of the authority stack. These provide profile credibility that helps the entire profile appear more naturally acquired. A small number of high-quality editorial links alongside a foundation of quality PBN links is consistently stronger than either type alone at scale.
How to Evaluate Any Guest Post Offer Before Buying
Apply these five checks to every guest post offer regardless of price:
1. Verify organic traffic independently. Open the domain in Ahrefs — Organic Search → Traffic. Any genuine traffic confirms Google trust. Zero traffic at any price point is a disqualifying condition.
2. Check the site in Google. Search for the domain on Google and read the pages that appear. Does the site look like a genuine editorial publication with a real audience? Or does it look like a content site created primarily for link sales?
3. Count outbound links on sample pages. Open three published articles on the site. Count the external links on each page. Pages with 20 or more external links are distributing PageRank broadly — your link receives a small fraction of what you might expect.
4. Read the existing content. Is the existing content human-written, informative, and topically coherent? Or is it thin, generic, and clearly produced at volume? The quality of existing content predicts the quality of the article your link will appear in.
5. Check the editorial process. Ask the seller how content is reviewed before publication. A genuine editorial site will describe at least a basic review process. A link farm will confirm it publishes everything submitted.

The Practical Recommendation
For most link building campaigns targeting low to mid-competition keywords with a budget of £50–£150 per link:
- Below £80: Quality PBN links on maintained domains with verified metrics consistently outperform cheap guest posts on equivalent budgets. Spend the budget on PBN links and invest any remaining capacity into content quality on your money site.
- £80–£150: Both quality guest posts and mid-tier PBN links deliver genuine value. Choose based on campaign priority — anchor control and speed favour PBN; editorial credibility and content depth favour guest posts.
- £150+: Premium editorial guest posts earn their price in YMYL niches and brand authority campaigns. For affiliate, e-commerce, and local campaigns, PBN links at this budget tier offer more placements at higher individual domain quality.
FAQ
What do cheap guest posts actually deliver?
At under £60, cheap guest posts typically deliver links on low-DR sites with minimal organic traffic, AI-generated or thin content, and no genuine editorial audience. Their ranking impact is minimal and rarely justifies the spend compared to quality PBN links at equivalent price points.
Is it worth buying cheap guest posts for SEO?
Below £50, rarely. The sites accepting cheap placements typically lack the authority and Google trust to meaningfully move rankings. At £80–£150, genuine editorial sites with real traffic become accessible and guest posts begin delivering real value. Below that threshold, PBN links consistently deliver better cost-per-ranking-improvement.
How do cheap guest posts compare to PBN links?
At equivalent price points under £80, quality PBN links on maintained domains almost always outperform cheap guest posts on low-authority sites. Both the domain authority and the organic traffic signals are typically stronger on a mid-tier PBN domain than on a link farm guest post site at the same price.
What is the minimum quality threshold for a guest post worth buying?
DR 20 or above, measurable organic traffic in Ahrefs, human-written content of at least 500 words, consistent publishing history of 12 months or more, and topical relevance to your money site. Below any of these thresholds the link is unlikely to produce meaningful ranking improvement.
What are red flags in cheap guest post services?
Same-day guaranteed placement, DA quoted without tool attribution, packages of 10+ posts under £100 total, pages with 50+ outbound links, clearly AI-generated content, and no editorial review process. Any of these signals indicate a link farm rather than a genuine editorial placement service.
When should I pay more for guest posts?
For YMYL niches requiring E-E-A-T signals, for brand authority building in publications your audience actually reads, for SaaS and B2B campaigns where industry publication credibility carries commercial value, and as the top layer of a mixed link profile that also includes quality PBN links as the foundation.
Conclusion
Cheap guest posts are not inherently worthless — but they are consistently oversold. The gap between what a £30 guest post costs and what it delivers in ranking terms is wider than most buyers realise before their first campaign underperforms. The quality floor for a guest post that meaningfully contributes to rankings is higher than the cheap end of the market typically provides.
For most campaigns where budget and speed both matter, quality PBN links on maintained domains with verified organic traffic deliver better cost-per-ranking-improvement below the £150 price threshold. Above that threshold, genuine editorial guest posts earn their premium in niches where editorial credibility and E-E-A-T signals are strategically important.
The optimal approach for most campaigns is not a choice between guest posts and PBN links — it is using both types at the right quality level for the right purpose. For quality PBN links that outperform cheap guest posts at equivalent price points — with full metrics transparency, indexed delivery, and permanent placements — explore the available options and apply the quality thresholds in this guide before every purchase.
