All-in-one SEO software for agenciesEvery client's SEO, run from a single screen.

First, the approach. SEMrush, Ahrefs and SE Ranking provide a wealth of data; it is up to you to interpret it, cross-reference it from one module to another and decide what to do. Zerkado adds a layer of artificial intelligence to every module that analyzes this data and turns it into concrete recommendations.

Instead of “your page has a score of 67/100”, Zerkado tells you, for example: “add a paragraph on this topic after the H2 "Y", rewrite the title tag, create an internal link to /services/audit”. You apply the recommendation; internal links can be added directly in WordPress.

Second, price and what it includes. As of this writing (October 2026), SEMrush's Pro plan costs $139/month for one user, with each additional user billed on top. At Zerkado, the Pro plan at €199/month includes 3 users, 2,000 AI credits; beyond 3 users, the Agency plan at €399/month includes 10.

Finally, Zerkado was born in French and is now available in five languages: French, English, German, Spanish and Italian. Our full comparison details the differences criterion by criterion.

Zerkado's technical SEO audit relies on an in-house crawler that checks 51 issue types across the pages of your website. It works in three steps.

1. The crawl. The crawler goes through your website by following internal links. It analyzes the HTML structure, meta tags, HTTP headers, Core Web Vitals (LCP, CLS, TBT), the robots.txt file, the XML sitemap, redirects and redirect chains, 404 errors, canonical tags and Schema.org structured data. Allow 2–5 min for a website with fewer than 500 pages, 15–30 min beyond 2,000 pages.

2. The analysis. Each issue is ranked into one of three severity levels, and the website gets an overall SEO score from 0 to 100.

3. The action plan. You get a ranked list, with a fix sheet for each issue. To learn more, read our guide to the technical SEO audit.

Yes: Zerkado is designed for agencies and consultants who work with several clients.

White labeling (depending on the plan: see pricing) puts your agency's branding on the platform: logo, colors, custom domain (audit.youragency.com) and reports. Your clients see your brand, not Zerkado's.

Multi-project management brings all your clients together in one dashboard. Each project has its own metrics, alerts and history, and you can switch between them in one click.

Automated reports: you set up the template once, and Zerkado generates the PDF reports and can send them to your clients on a fixed date.

The Agency plan at €399/month includes up to 40 projects, 10 users and 4,000 AI credits. For an agency with 30 clients, that comes to about €13 per client per month.

The rank tracking module records where your keywords rank in Google and saves the complete results page for each one.

Data collected: exact organic position, presence in featured snippets and People Also Ask, local results, competitors' positions, monthly search volume and history. Every change is dated.

Alerts notify you automatically of significant events: leaving the top 10 or dropping at least 5 places on a top-20 keyword, a backlink gained or lost, a crawl error, cannibalisation detected, a quota about to be reached.

Check frequency: each keyword at its own pace: daily in the top 10, every 2 to 5 days beyond. It can be set project by project. You can also run a check on demand, within your plan's daily limit.

The Content Copilot is Zerkado's AI content optimization module. It compares your page with the pages ranking in the top 10 Google positions for your keyword.

The semantic analysis finds the topics competing pages cover that are missing from yours: the “semantic gaps”.

The suggestions are specific: the AI proposes a complete paragraph, in your website's tone, and where to insert it. You accept, edit or reject it.

The content score changes as you apply the suggestions. The goal is not a perfect score, but to beat the average of the pages already on the first page of Google.

The backlink analysis module relies on SEO data from our partners.

Your backlink inventory shows for each link: the source domain, its authority, the link type (dofollow/nofollow/ugc/sponsored), the anchor text, the target page, the detection date and the current status.

Toxic link detection assesses the risk of each backlink by cross-referencing several signals, including the source domain's authority and spam score.

Competitive analysis lists the websites that link to your competitors but not to you: often your most accessible link building opportunities.

Yes. Zerkado offers a 14-day free trial with the Trial plan (1 project, 10 keywords, 50 pages crawled), no credit card required. Paid plans are subscribed to directly, with payment at sign-up. During the trial, you can explore the modules within the limits of the Trial plan: technical audit, rank tracking, backlink analysis, Content Copilot, reports and AI features.

Signing up only takes a few minutes. The first audit then takes 2–5 min for a site with fewer than 500 pages, up to 15–30 min above 2,000 pages; you get an SEO score, a ranked list of issues and an action plan.

At the end of the 14 days, you choose a monthly or yearly subscription (-17%), or you stop there, with no obligation. No hidden fees, no minimum commitment, and you can cancel in one click.

The internal linking module maps your website's internal links and finds room for improvement.

Orphan page detection reveals pages that receive no internal links, which makes them hard for Google to discover. Zerkado tells you which pages to link from, and with which anchor.

The internal PageRank calculation simulates how authority flows through your website. The AI recommends adjustments to direct it to your strategic pages.

Adding links in WordPress: once you approve a suggestion, Zerkado inserts the link in the chosen passage, with the suggested anchor. Compatible with BeTheme, Elementor, WPBakery and the native WordPress editor.

Yes. The rankings module spots the keywords whose results page shows an AI Overview box (formerly SGE). Whether your website is cited in it is measured in the AI visibility module, on the questions you track: this check runs on demand and is charged in AI credits.

GEO (Generative Engine Optimization) aims to make your content easy for answer engines (Google AI Overviews, ChatGPT, Perplexity) to cite: clear definitions at the start of paragraphs, factual data, comparison tables, numbered lists for processes and strong E-E-A-T signals.

The Content Copilot's recommendations point in the same direction: clear structure, sections to add, E-E-A-T signals. To learn more, read our GEO guide (in French).

It depends on your needs. For an agency, the deciding criteria are often: managing several clients, white labeling, cost per user, AI to automate repetitive tasks, and the working language of your team and your clients.

SEMrush and Ahrefs have very large databases; their cost does, however, rise with the number of users, and white labeling is limited or paid. SE Ranking is priced more affordably. The public prices as of October 2026 are shown in the comparison table above.

Zerkado is an all-in-one SEO platform designed for agencies: AI in every module, white labeling, multiple users included depending on the plan, and an interface in five languages.
