Buying guest posts on the marketplace

The serp.ac link marketplace (open it) sells guest posts, sponsored articles and link insertions on verified publisher sites. You buy from serp.ac: we are the seller of the placement service and pay the publisher as our supplier, so you have one contract, one receipt and one support team. You use your normal serp.ac account; there is no separate sign-up.

Finding a site

The Catalog lists every verified, approved site. Filter by:

• Niche: every niche is allowed, including crypto, gambling and adult. A site may charge a niche surcharge for some niches; the price you see already includes it once you pick the niche.
• Language, target market, price range, domain rank (DR, 0–100) and link type (dofollow, nofollow, sponsored).
• Placement: a guest post you write, a guest post the publisher writes, or a link inserted into an existing article.
• Turnaround: the number of days the publisher needs after accepting.

You can also search by domain and sort by price, rank, speed or newest. A site's page shows its metrics (domain rank, referring domains, detected language, last update, HTTPS), the publisher's rules, sample posts, completed orders and rating.

Ordering

1. On the site page choose the placement and the niche of your content.
2. For a guest post you write, paste the article (Markdown or plain text), upload a .txt, .md or .html file, or share a Google Docs link. For the other placements you only add notes.
3. Add your target URLs and anchor texts, up to the site's link limit.
4. Add to cart. You can order several sites and pay once.
5. Pay securely with your card through Stripe. Marketplace credit (from refunds) is used first if you tick the box.

Prices are fixed when you pay: a publisher's later price change never affects your order.

What happens after payment

Status	Meaning
Waiting for publisher	Paid. The publisher has 3 days to accept; otherwise you're refunded automatically.
In progress	Accepted. The delivery date is shown on the order.
Published, checking	The publisher submitted the URL; our checker is verifying it.
Verified, on hold	The link passed. The order completes automatically after 7 days unless you act.
Revision requested	You asked for changes.
Completed	Done; the guarantee runs.
Disputed	Our team is reviewing it.
Refunded	Ended without delivery; your money is back.

Automatic verification

When the publisher submits the URL we check that the page loads (HTTP 200) and is on the listed site, that every target link is there with the agreed anchor text and rel (a dofollow order needs dofollow), that the link isn't hidden, and that the page isn't noindex, blocked by robots.txt or canonicalized elsewhere. If something is wrong the order goes back to the publisher with the problems listed; you get a copy. We also queue a Google index check; it is shown on the order but never delays completion.

During the 7-day hold you can approve early, request a revision or open a dispute.

Link guarantee

For 6 months after completion we re-check your links. If a link is removed (or a dofollow link becomes nofollow), both you and the publisher are notified and the publisher has 7 days to restore it. If it isn't restored, you are refunded — as marketplace credit or to your card, depending on the case.

Completed links are also added to your link manager automatically when the target domain matches one of your projects (open link management), so they get the same daily checks as your other purchased links (how link management works).

Disputes and refunds

Open a dispute from the order when something went wrong (wrong content, late delivery after the deadline, a link that doesn't match). Our team reviews the order, the messages and the checks and may refund in full or in part, release the payment or give the publisher more time. Refunds go back to your card first; refunds Stripe can't process are added as marketplace credit.

Every order has a receipt page with serp.ac as the seller, and Stripe sends its own payment receipt.

FAQ

Who is the seller?

serp.ac. We sell the placement service and pay the publisher, so your receipt and contract are with us.

Can I order gambling or adult placements?

Yes, every niche is allowed. Publishers choose which niches they accept, and some charge a surcharge.

What if the publisher never accepts my order?

After 3 days it is cancelled and your payment is refunded automatically.

Do I have to wait for Google to index the page?

No. We record the index status, but the order completes once the link passed our checks and the hold period ended.

Where do I find my marketplace credit?

In the cart: when you have credit, a checkbox lets you use it at checkout.
