Interface

Serpzilla gives the essential information with some misses. However, they provide a few unique sets of information I haven’t seen in other guest-post marketplaces.

The platform provides information on the website traffic, traffic trend, domain authority metrics, and even authority metrics trend. The main things missing are geo-distribution and Semrush AS.

Serpzilla also shows a few unique metrics – the number of pages indexed by Google and the number of outbound links per page on the site.

So, overall, that’s a good amount of information, except for one or two misses.

Buying backlinks

I had specific criteria in choosing the sites I wanted backlinks from. That’s how any user journey goes in these marketplaces.

As a user, I want to promote my Content Audit Tool on a truly authoritative website. So, here are my criteria:

1. The publisher’s website must receive at least 1,000 monthly visits from organic traffic. I want a backlink from a Google-recognized site.
2. The traffic should be stable or growing, not declining. Links from a site whose traffic is nosediving provide little value to me.
3. The traffic source should be the US, as it’s my home market, and 90% of my audience is based here.
4. The publisher’s relevance matters for topical authority. A cooking website isn’t the best place to promote an SEO SaaS tool. So, I need to filter for the website industry.
5. I want a Semrush Authority Score (AS) higher than my website’s, which is 24 as of today. I don’t consider legacy metrics from Moz, Ahrefs, and Majestic, as they became useless after Google’s Useful Content Update in March 2024. DA and DR were too easy to manipulate for years before the March update.
6. I prefer the content publisher or platform copywriter to create content following their guidelines, using my input as the foundation.
7. Lastly, I want to spend $200 or less on my backlink. Price matters.

So, I set out to filter for these criteria.

I was able to filter for price, traffic, and site category/topical relevance easily. I could see the traffic trend (as this micro bar graph) later.

To be honest, Serpzilla provides lots of filters, a few of them are highly technical. But I’m disappointed they missed the filter by country and by Semrush AS metric. Apart from those two, I liked the wide filtering options provided.

Data accuracy

Next, I checked the data accuracy of these listings by picking a site at random. Mainly the traffic data.

This is where things get interesting.

The traffic estimate Serpzilla provides for its publisher sites is confusing.

For a few sites, the traffic is apparently measured by Serpzilla counter through the Javascript code they’ve placed on the publisher site.

For others, the traffic data comes from Yandex Metrica. And Serpzilla also tries to provide Ahrefs and Semrush traffic estimate, which unfortunately, returns with no data for most of their sites.

I picked a site that shows traffic estimates from Serpzilla and Ahrefs.

According to Serpzilla, this site has a monthly traffic of 85K.

And according to Ahrefs, the site gets 20.6K monthly traffic.

Now, I cross-checked the traffic data on Ahrefs. And it shows a higher traffic data – 37.8K. Ahrefs was showing 22K traffic two months ago. Probably, Serpzilla isn’t frequently updating the Ahrefs data.

Serpzilla’s own traffic estimate (85K) seems a bit too optimistic as well.

Semrush shows the publisher site traffic at 57K. Serpzilla gives the most optimistic traffic figures out of all.

In the end, we can’t really say for sure which traffic data is the most accurate, since they’re all estimates. But Serpzilla could benefit from updating the Ahrefs and Semrush data more frequently.

Customer support speed and quality

Based on our initial interactions, Serpzilla’s customer support has been responsive, and their reply was pretty helpful.

We’ll provide a more detailed assessment of their support speed and response quality soon.

Public reviews responsiveness

Serpzilla has a poor review rating on Trustpilot. However, the rating is based on only four reviews–which is not enough sample size to draw any conclusion.

Since it’s just one bad rating, we are not looking too deeply into this. With a handful of reviews, it’s difficult to gauge how honest and transparent those reviews are to form an opinion about the service.

Bottomline

We consider Serpzilla a legit guest-post marketplace.

The platform provides excellent filters with lots of customization, decent data metrics, and good customer support. Downsides include the lack of traffic by country and Semrush AS data metrics for publisher sites, and limited public visibility.

Overall, we consider Serpzilla a decent guest-posting platform to look towards.
