Everyone selling guest posts says theirs are high quality. The phrase has been used so much it barely means anything. So here's what I look for, as someone who's bought placements for years and now publishes them on my own blog.

What makes a guest post high quality?

Quality sits in two places: the site, and the post. You need both. A great article on a dead site is wasted, and a thin article on a strong site drags the page down.

The site

• It's live and indexed. On my list of 3,204 guest post sites, 18% were dead or parked when I checked in September 2026. Search site:domain.com and see what comes back.
• It's on topic. A marketing tool belongs on a marketing blog. Relevance beats raw authority.
• It's still publishing. Recent posts mean an editor is still paying attention.
• It has readers. Comments, shares, a newsletter or social following are all signs of a real audience.
• It has a named owner. Someone you can email if a link breaks or a page moves.

The post

• It answers a real question. The best guest posts would be worth reading with no link in them at all.
• The link fits the sentence. Your link goes where it helps the reader, not bolted onto the last paragraph.
• It suits the site's audience. Same tone, same depth, same kind of reader as the rest of the blog.
• It's original. Never published anywhere else.
• It stays up. Ask how long the post will stay live. On my blog, it's permanent.

How do you check guest post quality before you buy?

This takes about ten minutes per site:

1. Search site:domain.com and check the number of indexed pages looks healthy.
2. Open the three newest posts. Are they useful, or thin and link-heavy?
3. Look at the site's traffic trend in any SEO tool. Rising or steady is good; a cliff is a warning.
4. Check the traffic split by country against your target market.
5. Find the owner or editor. A name and an email address are a good sign.
6. Ask for an example of a published guest post and look at how the links sit.

For the link side in more depth, read how to check backlink quality. And if you're weighing up whether to buy at all, I've covered that in is it worth buying backlinks for SEO.

What are the red flags of a low quality guest post site?

• It covers everything, with no clear readership.
• Every recent post is a sponsored article with a link.
• The seller won't name the site until after you've paid.
• There's no author, no editor and no contact name.
• Pages you placed on before have dropped out of Google.
• Promises about rankings or traffic that nobody could guarantee.

Does domain authority decide quality?

No. Authority scores are useful for comparing sites, but they're third-party estimates, not Google metrics. A site with a lower score that's on topic and growing is often a better placement than a high-scoring site that's lost its traffic. I use authority as one filter, then judge relevance and life signs by hand. My guide to high DA guest posting sites goes into this.

Is a link insertion lower quality than a new guest post?

Not necessarily. A link insertion puts your link into an article that's already indexed and already has a history. For many SEO goals, that's the stronger option. A new post suits you better when you want a full article on your topic that you can share.

How I keep guest posts on my blog high quality

lilachbullock.com is a marketing blog that's been publishing since the dial-up days, with thousands of indexed articles and readers who are business owners, marketers and entrepreneurs, mostly in the USA and the UK. I edit every post before it goes live, and I turn down:

• Thin articles written only to carry a link
• Anything already published elsewhere
• Content that's inaccurate or misleading about what a product does
• Posts that attack a person or company

That protects my readers, and it protects the value of the page your link sits on.

How placing a post on my blog works

1. Email [email protected], or start on my write for me page, with your target URL, topic and niche.
2. I reply with whether it fits and which format I'd pick: a new sponsored post or a link insertion into an existing, indexed article.
3. You send the article, or I choose the right existing article for your link.
4. I edit, publish and send you the live URL.

Accepted posts usually go live within 24 to 48 hours of everything being agreed. Placements are permanent. I invoice by PayPal, and if you're an agency, I never contact your client.

If you're an agency placing for clients, the white label guest posts page explains how I handle that. If you're building a shortlist of other sites, start with my free list of websites that accept guest posts, which I re-checked site by site in September 2026.

Frequently asked questions

What is a quality guest post?

A useful, original article on a relevant, live site with real readers, where your link sits naturally in the text and the post stays up permanently.

How can I check if a guest post site is good?

Check it's indexed, still publishing, relevant to your niche and run by a named person. Read its newest posts and look at its traffic trend.

Is high DA the same as high quality?

No. Authority scores are third-party estimates. Relevance, real readers and a site that's still growing matter as much or more.

Can I see the site before I order?

You should always be able to. On my blog, you know exactly where your post will go, because it's lilachbullock.com.

Do you edit guest posts?

Yes. I edit every post for my audience before it goes live and tell you what changed.

How much does a guest post on your blog cost?

It depends on the niche, the format and the volume. Email your details and you'll get a clear answer.
