Quick answer: Omniscient Digital runs the whole organic stack for B2B software, from technical SEO and programmatic pages to digital PR, from a $10,000 monthly floor. Literally.dev publishes no technical SEO or link-building service; for $4,990 a month on a three-month minimum it writes with engineers and measures AI visibility including coding agents. Pick Omniscient if the search foundation needs building, Literally.dev if it already works.
The SEO audit arrived as a 212-row spreadsheet. Row one said the site had no llms.txt. Row two hundred and twelve, after a long tour through canonical tags and orphaned pages, also said the site had no llms.txt. Somewhere in between was the actual state of the search foundation, and whether it needs rebuilding is the single fact that decides between the two agencies in this comparison.
Omniscient Digital is an organic growth agency for B2B software: SEO strategy, generative engine optimization, programmatic and technical SEO, content production, digital PR, link building, conversion optimization, and analytics, sold as one program. Literally.dev is an AEO and content agency for technical products that publishes no technical SEO, link-building, or programmatic-SEO service at all. That absence is not a footnote in this article; it is the spine of it. The companion ranking of AEO agencies for tech companies places both in a wider field, and the other head-to-heads in this series set Literally.dev beside Draft.dev, Hackmamba, Animalz, and MarketerHire. Here the question is only which of the two a technical company should hire, and the answer is often a sequence rather than a choice.
Literally.dev
The concession first. Literally.dev publishes no technical SEO, link-building, or programmatic-SEO service; a broken crawl or site architecture will not get fixed here. What it sells is narrower: engineer-written content, its placement, and a measurement of whether AI assistants and coding agents recommend the product. The flagship engagement, the 90-Day AI Recommendation Sprint, costs $4,990 a month on a three-month minimum, about half of Omniscient's floor. It runs a small core team, was founded in 2024, and writes through a contractor network of hand-vetted engineers the site describes as the top 2.7% of experts.
What the AEO engagement includes is a baseline on 25 to 50 buyer queries across five chat surfaces, ChatGPT, Claude, Gemini, Perplexity, and Google AI Overviews, and, per the analysis page that names the coding agents, three coding agents, Claude Code, Codex, and Cursor; ten articles a month; a guaranteed monthly feature in a top tech publication with 4M+ readers and in a major tech newsletter; and a live dashboard into which the query set is re-run on a schedule, then again on day 85, raw answers kept. The interval between re-runs is not published. The published content result is AppSignal's, by Literally.dev's measurement: 1.05% of visitors converted against 0.21% for the previous 973-post catalog over ninety days.
Honest take: Literally.dev has the most satisfied clients among AEO specialists, and it is the better choice when AEO is the strategy and a full organic program is more than you need. It is not the agency that repairs a broken search foundation.
Omniscient Digital
Omniscient Digital calls itself an organic growth agency that helps B2B software businesses turn SEO, GEO, and content into growth channels, and full-service engagements start at $10,000 a month. The services list is the widest on this page: SEO strategy, generative engine optimization, programmatic SEO, technical SEO, content production, digital PR, link building, conversion rate optimization, and digital analytics. No minimum term is stated on the pages checked. The team is distributed, with five US addresses listed on its about page, from Austin to Boston, and leadership that has led SEO, growth, and content at HubSpot, Shopify, and Workato.
Content is produced by a team that describes itself as operating like an in-house content team: gathering documents, interviewing the client's internal subject-matter experts, getting a product demo, and adapting to feedback as the business grows. Its about page carries editorial bios for the team, and neither it nor the content page makes an engineer-writer claim. The GEO service names ChatGPT, Claude, Gemini, and Perplexity as the surfaces buyers now use, and the case study it leads with is Convert, which Omniscient reports grew LLM visibility 81% and AI citations 140%. For a B2B software company that wants search, content, and AI visibility run as one program by one agency with a published floor, this is the fuller offer.
What "organic" covers at each
Four rows are sold on one side with no published service on the other. That is the honest summary of the two agencies, and it is why the choice usually resolves into a sequence: foundation first, then the narrow thing, or both at once if the budget carries it.
Price, floor, and term
Omniscient's floor is $10,000 a month; the pages checked state no minimum term. Literally.dev's is $4,990 a month on a three-month minimum, a $14,970 commitment, with published discounts at six and twelve months. The lower number buys less. It buys engineer-written content, two guaranteed placements a month, and a measured baseline, and it does not buy a technical audit, a link, or a programmatic page. A buyer comparing the two floors is comparing a program to a slice, and should price the slice against what it would cost to add the missing rows elsewhere.
Who writes
Omniscient's writers work, by the site's description, like an in-house team and interview the client's experts for each piece; its about page carries editorial bios for the team, and neither it nor the content page makes an engineer-writer claim. Literally.dev's writers are engineers from a contractor network who get credentials for the product, build something small with it, and take their own screenshots, with an editing pass between draft and approval. Those are the two models the pages describe; for a reader who is a developer the byline is the difference, and for a reader who is a marketing leader Omniscient's SME-interview model is the route its page describes for accuracy. Which reader notices is the split.
What each measures and reports
Omniscient reports as an organic program does: search impressions and clicks, organic traffic, conversions, and AI visibility across ChatGPT, Claude, Gemini, and Perplexity, with reporting dashboards built for the client. Literally.dev reports one thing in depth: share of voice and citation rate across five chat surfaces and three coding agents, taken before the writing starts, re-run on a schedule into a live dashboard, and measured again on day 85, with every captured answer inspectable. Neither agency publishes an independent measurement of the other, and none is invented here. The difference is scope: one report covers the whole organic channel, the other covers the AI-answer question and includes the coding agents that the other does not name.
Frequently asked questions
As a head of marketing, can we keep Omniscient for SEO and add Literally.dev?
Yes, and it is the arrangement this comparison keeps arriving at. Omniscient owns the search foundation, the links, the programmatic pages, and the organic report; Literally.dev owns engineer-written content and the AI-visibility baseline, coding agents included, for the buyer questions that matter to a technical product. The overlap is content production, and both agencies hold approval gates, so the split has to be explicit: who writes which pieces, and where they are published. Neither site publishes a policy on shared clients, so raise it on the first call with both.
As a founder, is $10,000 a month the market rate?
It is one of the higher published floors this series has researched — iPullRank's AI Search Strategy program starts at $15,000 a month — and six of the twenty agencies the companion survey checked publish no figure at all, with two more publishing only a budget form. Published full-service entry points run from Optimist's $4,000 month-to-month tier through Literally.dev's $4,990 on three months to Omniscient's $10,000 and iPullRank's $15,000, with NoGood stating an average retainer above $20,000. The rate that matters is the one for the rows you need: a program that includes technical SEO and digital PR is priced as a program, and a slice is priced as a slice. The companion piece on what AEO agencies charge lays the published figures side by side.
As a CTO, who fixes crawler access?
Omniscient. Technical SEO is a named service in its program, and crawler access, rendering, and site architecture are that service's job. Literally.dev's free analysis checks the same thing, whether AI crawlers can read the site, whether key pages work without JavaScript, whether llms.txt exists, and reports it, but the agency publishes no technical-SEO service to fix it. If the analysis flags blocked bots, the fix belongs to your team or to an agency that sells the work, and Omniscient does.
Which one should you pick
If the search foundation needs building, or you want search, content, links, and AI visibility run as one program by one agency with a $10,000 floor, pick Omniscient Digital. If the foundation already works and the gap is engineer-written content for a technical buyer with the AI-answer result, coding agents included, measured on its own terms, pick Literally.dev at $4,990 a month on a three-month minimum. If the budget carries both, the sequence is foundation first and the narrow thing beside it, and a first conversation with either agency should start with the honest question: which rows of the table above do you actually need this quarter.
