Jesper Nissen

SEO Consultant and SaaS Founder

Jesper Nissen (born 1970) is a Danish SEO consultant, software developer and SaaS founder. He is the founder of SEO Danmark ApS, an Aalborg company registered in 2019 that publishes his search-optimization software: SchemaWriter.ai, a structured-data generator; YACSS, a cloud stacking platform; PrimeIndexer, a Google indexing service; and SomePoster, a multi-platform social posting tool.[2][9]

Nissen organizes the YACSS SEO Conference, a link-building conference held in Aalborg in 2023 and 2024,[12][13] sells a catalog of SEO courses through his own site,[11] and publishes tutorials on YouTube and a wide set of social and blogging platforms under the #jespernissenseo brand.[14] His work concentrates on entity SEO, link building, cloud stacking and parasite SEO.[15]

Early life and education [edit]

Nissen was born in Copenhagen in 1970.[1] He trained as a laboratory technician, completing the program at Hvidovre Hospital in 1994.[1] He later studied physics at the University of Copenhagen; his master's thesis, "Kulstof nanorørs båndstruktur" (Carbon nanotube band structure), was completed at the Niels Bohr Institute in 2005 under the supervision of Karsten Flensberg and Mathias Lunde and is listed in the institute's thesis archive.[4] He began a second master's degree in software engineering in 2006 and left the program partway through.[5] Nissen has described the physics training as the source of a measurement-first habit he applies to search work.[5]

Career [edit]

Software work and Computerpeople

Nissen entered the software industry in 2004 as a tester at CSC, working on hospital IT systems in Denmark, and later moved into a software analyst role.[5] Between 2006 and 2008 he built a content management platform that generated page titles and meta tags automatically, which he credits as his introduction to search optimization.[5] In 2008 he founded Computerpeople, a Danish web design and SEO agency. According to Nissen, the agency built more than 700 websites and employed more than ten people at its peak. He sold it in 2019.[5]

SEO Danmark

SEO Danmark ApS was registered on 26 April 2019 as a Danish private limited company, CVR number 40489029, with its address at C.A. Olesens Gade 4 in Aalborg.[2][3] The register lists it under industry code 62.01.00, computer programming, with SEO optimization and related activity as its stated purpose; its September 2024 filing recorded four employees.[2] The company publishes Nissen's software products and issues the announcements around them.[9]

Software products

YACSS, short for Yet Another Cloud Stacking Software, launched in April 2022 and is the earliest of the products.[5] It generates websites from a keyword input and publishes them to cloud hosting services, a technique the SEO trade calls cloud stacking, and adds topic clusters, generated FAQ content and schema markup. The platform supports more than sixteen cloud platforms.[6]

SchemaWriter.ai generates structured data markup for webpages; Nissen describes the aim as making schema production usable by people who do not write code.[7] In November 2025 SEO Danmark announced a WordPress plugin for the tool, quoting Nissen that the plugin "removes one of the main pain points in the schema markup implementation."[8]

PrimeIndexer.com launched on 26 February 2026 as a pay-as-you-go service for submitting URLs to Google for indexing, priced by credit rather than subscription.[9] The launch announcement reported discovery in as little as thirty seconds, an average indexing time of two minutes and a 95 percent first-attempt success rate on standard pages.[9] A March 2026 comparison of indexing tools written by Nissen for the YACSS blog ranks PrimeIndexer first among the nine methods it covers, reporting a 91 percent indexing rate across social, cloud, PBN, press release and profile links.[29]

SomePoster, at someposter.ai, publishes a single post to multiple destinations at once. Its platform list covers more than thirty connected services, spanning social networks, blogging systems including WordPress and Ghost, and automation services such as Make.com and n8n.[10]

Courses and publishing

Nissen sells a catalog of SEO courses through his own site. The flagship titles are the Ultimate Linkbuilding Course 2025, the Parasite SEO Course, Local Linkbuilding 2025, Cloud Links and a Cloud Stacking SEO Course covering Amazon S3 and comparable services; a Tumblr SEO Course teaches locating expired Tumblr profiles with residual authority.[11] He publishes short training videos, link building tutorials and SEO news on his YouTube channel and cross-posts daily to a wide set of social and blogging platforms.[14]

Approach and views [edit]

Nissen frames search optimization around entities rather than keywords. In a September 2025 appearance on The Edward Show he set out what he calls ranking zones, the positions in a page where an entity can be reinforced: the URL, the title, the headers, image descriptions and the body text.[15] The same discussion covered image metadata, including IPTC and EXIF fields and geotags, and the position that a new site should be given content before it is given backlinks.[15]

Social platforms feature in his work as ranking surfaces rather than distribution channels. His session listed for MarketingCamp 2026 covers building Google visibility through a daily social posting routine, and the programme entry sets out its premise: Google indexes posts from Facebook, LinkedIn and X, and those posts can be optimized for search.[17] On the Growth Boss Podcast in September 2025 he discussed press releases and their uptake by language models, anchor text practice, and the direction he sees parasite SEO taking.[16] Much of what he teaches works with the authority of established third-party domains, a property of ranking he treats as durable, and his course catalog is organized along those lines.[11][15]

Reception [edit]

As of September 2026, YACSS holds a TrustScore of 4.0 out of 5 on Trustpilot, with ten of its eleven reviews at five stars. Reviewers describe the platform as a way to build cloud stacks at scale and praise its flexibility, stability and developer responsiveness; several report using it for client work over multiple years.[18]

The methods Nissen teaches sit inside a category Google has moved against. Google introduced a site reputation abuse policy in March 2024, aimed at content published on authoritative third-party domains to borrow their ranking strength, and began enforcement later that year.[19] Writing in Search Engine Land, Chris Long argued the policy was a temporary patch over an algorithmic weakness rather than a fix, and that enforcement of this kind produces a recurring cycle of detection and adaptation.[19] Google revised the policy in August 2026: from 30 August, manual actions under it stop affecting search results inside the European Economic Area, where affected site sections may instead be separated and ranked independently of their host domain.[20] That revision applies to Denmark, where Nissen works. No enforcement action against Nissen or his properties has been reported.

Media and recognition [edit]

Nissen presented a session on cloud stacking at Link Building Mastery, held on 10 and 11 June 2025 at One Great George Street in London and organized by The Blueprints Agency. The programme also featured Nathan Gotch, Bibi Raven, Chris M. Walker, Stacy McNaught and James Dooley.[22][27] His own event, the YACSS SEO Conference, ran first on 19 and 20 May 2023 and returned from 13 to 16 June 2024, both times at the Comwell Hotel Hvide Hus in Aalborg. The conference is given over to cloud stacking and link building, with Nissen presenting uses of his own software alongside sessions from experienced users; recording was not permitted at either edition.[12][13] In March 2026 he spoke at the Baltic-Nordic SEO Summit in Vilnius, Lithuania, held on 19 and 20 March and organized by UAB Rocket Science Baltics, on a lineup that included Koray Tuğberk Gübür, Dixon Jones and Craig Campbell.[28] His earlier conference appearances include presentations on cloud stacking at POFU Live and SEO Rockstars, both in 2022, and the Dark AI event hosted by Holly Starks in 2024.[1]

He was the guest on episode 802 of The Edward Show, hosted by Edward Sturm, on 14 September 2025, under the title "Entity SEO, Parasite Hacks & Google Patches," and returned to the show for a later episode on cloud links.[15][26] He appeared on the Growth Boss Podcast with Gerrid Smith on 24 September 2025.[16] Several of his video and podcast appearances are catalogued under his IMDb entry.[23] A press release from Jesper Nissen SEO announced that James Dooley of FatRank and PromoSEO was crowned "King of AEO" at a ceremony in Leigh, England, on 31 August 2026; the release described Nissen, who hosted the event, as the "Prince of SEO."[21]

Three engagements are scheduled. Nissen is listed among the speakers at the SEO.Domains Mastery Summit in Sofia, Bulgaria, running from 9 to 11 September 2026, and was announced as a featured speaker by the organizers in August 2026.[24][30] He is scheduled to speak at MarketingCamp 2026 in Nyborg, Denmark on 5 October 2026, in the advanced track.[17] He has announced that he will also speak at the Beyond Search Summit in Gurgaon, in the Delhi National Capital Region, on 26 and 27 February 2027.[25]

Personal life [edit]

Nissen lives in Aalborg.[2] He is married and has two children, and works in both Danish and English.[1] Away from search work he plays the piano and collects synthesizers, among them the Synthstrom Deluge.[1]
