SEO services that turn Google into a revenue channel
DePaul Marketing runs full SEO programs for US businesses: technical foundations, content built around topical authority, and links earned through real outreach. Measured in leads and revenue, reported in plain English.
Our SEO services cover the four things rankings actually depend on: a technically sound site, pages matched to what buyers search, topical authority built through structured content, and links from real websites. Programs run month to month against a written plan, typically $1,500 to $7,500 depending on your market, with early movement in 60 to 90 days and compounding growth from there.
What is included in our SEO services
SEO is a system, not a bag of tricks. Every program covers four connected workstreams, weighted to what your audit shows you need most.
Technical SEO
Crawlability, indexation, site speed, Core Web Vitals, structured data, and architecture. The foundation everything else stands on.
Technical SEO service → ✍️Content and topical authority
Hub and spoke content maps that make your site the obvious answer for a topic, not a site with a few lucky posts.
Content marketing service → 🔗Link building
Digital PR, guest contributions, and relationship outreach that earn links Google trusts. No purchased networks, no spam.
Link building service → 🤖AI search and GEO
Entity clarity, extractable answers, and schema so ChatGPT, Perplexity, and AI Overviews cite you when buyers ask.
AI search service →Who this service is for
SEO rewards businesses that can wait months for a channel that then compounds for years. It fits you if at least two of these are true:
- A customer is worth $1,000 or more, or buys from you repeatedly
- People already search for what you sell, and you can name those searches
- You are paying for every lead today and want a channel you own
- You can invest for at least six months before demanding a verdict
It fits poorly if you need leads this month with no bridge budget, or if nobody searches for your category yet. In the first case start with Google Ads while SEO builds. In the second, demand creation through paid social comes first.
Our SEO process
Forensic audit
Crawl, index coverage, speed, content inventory, link profile, and competitor gap analysis. You see exactly why you rank where you rank.
Keyword and intent map
Every target keyword gets classified by buying intent and assigned to a page, existing or planned. This map is also our cannibalization control: one intent, one page.
Build sprint
Technical fixes ship first, then priority pages and content on a published calendar. You see drafts and changes, not summaries of them.
Authority and iteration
Link outreach runs continuously. Pages that show movement get expanded and internally linked deeper. Pages that stall get diagnosed and rebuilt, not abandoned.
What most SEO agencies get wrong
They chase volume instead of intent. A keyword with 10,000 monthly searches and no buying intent produces traffic that bounces. A keyword with 90 searches from people ready to hire produces customers. We would rather rank you for 40 of the second kind.
They publish content without an architecture. Random blog posts do not build authority. Search engines reward sites that cover a topic completely and connect that coverage through internal links. That is why every content plan we write is hub and spoke, not a list of titles.
They report activity, not outcomes. "We published 4 posts and built 6 links" is a receipt, not a report. Our reports lead with qualified leads and revenue-adjacent metrics, with rankings and traffic as supporting evidence.
They ignore where search is going. A growing share of answers now appear inside AI Overviews and assistants. Sites structured for extraction win citations there; sites that ignore it donate their expertise to competitors who did the structuring.
Is SEO worth it? The honest math
Take your average customer value, multiply by realistic monthly leads from ranking positions in your market, and compare against program cost over 12 months. For a service business worth $3,000 per customer, a program producing 8 extra customers per month returns its annual cost many times over. For a $40 product with no repeat purchases, the same program may never break even. We run this math with you before proposing anything, and we will tell you when the answer is no.
People Also Ask
What is the difference between SEO and local SEO?
SEO targets organic rankings wherever your buyers are, including nationally. Local SEO adds the map pack, Google Business Profile, reviews, and proximity signals for businesses serving a physical area. Most local companies need both, weighted toward local.
Should I do SEO in-house or hire an agency?
In-house works when you can hire strategy, content, and technical skills together, which rarely fits one salary. Agencies bundle those skills and tooling. A hybrid model, your team on brand and approvals with an agency on execution, is often the best value.
How many keywords should a business target?
Fewer than most plans claim. A focused program targets 20 to 60 keyword clusters mapped to specific pages, then expands from what wins. Thousand-keyword lists usually signal reporting theater rather than strategy.
Does website design affect SEO?
Directly. Speed, mobile experience, heading structure, and internal linking all shape rankings, which is why our web design and SEO teams work from the same playbook. A beautiful site that loads in six seconds is a beautiful liability.
Frequently Asked Questions
Competent SEO programs in the US run $1,500 to $7,500 per month depending on market difficulty and how much content and link work is needed. Local single-location programs sit lower, national and ecommerce programs higher. Our pricing page publishes full ranges so you can compare any quote.
Expect early movement in 60 to 90 days and meaningful lead growth in 4 to 9 months for most markets. Sites with existing authority move faster. Brand-new domains in competitive niches take longer. Anyone quoting page one in 30 days is selling something other than SEO.
No, and neither does anyone honest. Google's results shift constantly and no outside party controls them. What we commit to in writing is the work itself: the pages, fixes, content, and links shipped each month, plus reporting that ties the work to leads.
AI search changes where answers appear, not whether visibility matters. ChatGPT, Perplexity, and AI Overviews all cite sources, and those citations skew toward well-structured, authoritative pages. Our programs build for classic rankings and AI citations at the same time, because they draw from the same foundations.
Usually, once we diagnose the cause. Drops come from algorithm updates, technical regressions, lost links, or content quality issues, and each needs a different fix. We start with a forensic audit comparing your traffic timeline against update dates and crawl data before touching anything.
