How we engineer rankings.

A five-phase loop, repeated continuously. No black boxes — every step traceable to a measurable signal.

seo.co — process.ts
01
$ seo.audit()
Diagnose

200-point technical, content, and backlink audit. Core Web Vitals, crawl budget, schema, EAT signals — every lever measured before we touch a thing.

02
$ seo.strategy()
Cluster

Keyword universes mapped to topical authority pillars. Intent matched to content. Internal-link graph designed before a single page ships.

03
$ seo.execute()
Build

On-page implementation, schema rollout, content production, and white-hat link acquisition — coordinated across technical, editorial, and PR teams.

04
$ seo.measure()
Track

Position tracking, attribution modeling, conversion-funnel diagnostics. Weekly reports tied to revenue, not vanity metrics.

05
$ seo.optimize()
Iterate

Algorithm-update response within 48 hours. Competitive deltas surfaced in real time. Continuous remediation on the pages losing ground.

Schema-first because Google reads JSON, not paragraphs.

Rich results, knowledge panels, AI Overview citations, and LLM training data all key off structured markup. We deploy validated JSON-LD across every page, monitored for drift.

  • 30+ schema types covered (Organization, Service, FAQ, HowTo, Article…)
  • Live Rich Results validation in CI
  • Schema audit included in every engagement

Our Content Writing Process

Website Audits Showcase Technical Deficiencies & Behavior Analytics to Improve On-page & Off-page Website Health

Our SEO services include a full audit report will provide you with a detailed plan of attack for fixing specific on and off-site errors and deficits as well as provide suggestions for internal linking and off-site link procurement for immediate keyword growth.

Clients Trust Our Content Services

  • Choose a campaign. We have serviced thousands of clients over the last decade. Available work among existing and new clients is plentiful. Our writing jobs range from 500 words to 5,000 words, and everything in between.
  • Company & Industry Research. Because our content writers produce hard-hitting SEO copy, each writer needs to do industry and company research. This ensures the content effectively matches the brand and industry and hits the relevant keywords.
  • Draft Hard-Hitting Copy. The quality of your content is what matters most. Yes, computers can produce content – but it doesn't compare to human-produced content. Customers choose among writers, so make your product shine.
  • We Hire for More Work. Some of our writers have been with us for almost a decade! If your work is quality, clients will want you back. The better your content, the more you will be re-hired by a client or member of our team.
  • Go Niche & Get Friendly. Our clients are typically on recurring retainers for content production. When a client finds a writer that stands out, they typically come back for more. The better you write for a given niche and build relationships, the more likely you are to find ongoing work.
  • Get Paid. We batch process writer invoices every two weeks. Regardless of whether you have completed 1k words or 20k words, your money will hit your account on the 1st and 15th like clockwork.
