What Strategies Does an SEO Company Use to Improve Search Rankings?

There’s no single lever that moves rankings. An SEO company that’s actually doing the work is running several categories of strategy at once, technical, content, authority, and on-page, and adjusting the mix based on what’s holding a specific site back. This guide is the map of how those pieces fit together at a strategic level. Each category has its own dedicated, much deeper guide linked below; this page won’t re-explain the mechanics of any one of them, it’s here to show how an agency sequences and balances them across a campaign.

The general default sequence, in the order most agencies default to before a site-specific audit changes the priority:

  1. Technical foundation. Fix crawl, indexing, and page experience issues before anything else, since they cap what content and links can accomplish.
  2. Content matched to search intent. Build coverage against a documented keyword and intent map, not whatever topic seems timely.
  3. Authority through backlinks and brand signals. Earn external validation through the channel that fits the client, digital PR, structured outreach, or local citations.
  4. On-page signals. Tighten title tags, meta descriptions, header structure, and schema once the bigger levers are already working.
  5. AI Overviews and shrinking click pool adaptation. Re-weight toward queries less dominated by AI Overviews and toward earning citations inside AI-generated answers.
  6. Continuous tracking and re-weighting. Measure rankings, traffic, and conversions against the original strategy and adjust which category gets the next round of investment.

Start With a Technical Foundation That Doesn’t Block Everything Else

Content and links can’t compensate for a site Google can’t crawl, index, or render properly. Before investing in anything else, agencies typically run a technical audit to catch indexing problems, broken canonical tags, crawl traps, and page experience issues that cap how much the rest of the strategy can accomplish. Two factors get particular attention here: how easily Google’s crawlers can discover and index every important page, and how the site performs on Google’s page experience signals, including Core Web Vitals.

We don’t re-cover the mechanics of either in this guide, since both have their own full breakdown: see our crawlability and indexing guide for the technical audit process, and our UX and Core Web Vitals guide for how page speed and usability factor into rankings. The strategic point at this stage is sequencing: fixing a major technical blocker before scaling content production, because content built on a broken technical foundation underperforms regardless of quality.

Build Content That Matches Search Intent and Demonstrates Real Expertise

Once the technical foundation is sound, content becomes the primary lever for capturing search demand. The strategic decision here isn’t whether to publish content, it’s what to publish and in what sequence: which search intents to target first, how to structure topic coverage so related pages reinforce each other instead of competing for the same query, and how to signal genuine subject-matter expertise rather than surface-level coverage.

The actual mechanics of intent matching, content depth, and E-E-A-T signals belong to our content optimization guide, and the long-term planning side, content calendars, pillar-and-cluster architecture, and content refresh cycles, is covered in our content strategy guide. At the strategy level, what matters is that content decisions get made against a documented keyword and intent map, not published reactively based on whatever topic seems timely that week.

Earn Authority Through Backlinks and Brand Signals

Google still weighs external validation heavily, in the form of backlinks from relevant, trusted sites and broader brand signals like being mentioned, searched for by name, and cited across the web. The strategic question agencies work through is which link-earning channels fit a given client: digital PR and earned media for a brand with a genuine news hook, structured outreach and guest contribution for a B2B service business, or local citation building for a business that competes primarily on geography. The tactics and outreach methods themselves are detailed in our link building strategies guide, and how link building fits into the broader concept of domain authority is covered in our domain authority guide.

Tighten On-Page Signals Without Over-Engineering Them

Title tags, meta descriptions, header structure, internal linking, and structured data all give Google explicit signals about what a page is and how it should be displayed in search results, including which rich results (FAQ snippets, product markup, review stars) a page becomes eligible for. This work matters, but it’s typically the fastest category to execute well and the easiest to over-invest in relative to its impact once the basics are correct. The full mechanics of meta tag optimization and schema markup are covered in our on-page SEO guide; the strategic note here is that on-page work should follow technical and content strategy, not substitute for them.

Account for AI Overviews and the Shrinking Pool of Clicks

This is the strategic shift that’s reshaped how agencies sequence everything above. Google’s AI Overviews now appear on a meaningful share of search results, with measurement varying by methodology: Conductor’s analysis of nearly 22 million searches in late 2025 found AI Overviews triggering on roughly 25% of queries across a broad, mixed sample, while BrightEdge’s year-over-year tracking found the feature appearing on about 48% of tracked queries by February 2026, up from roughly 31% a year earlier, with much higher concentration in categories like healthcare and B2B technology. The range reflects different query samples and tracking methods, but the direction is the same everywhere: AI Overviews are becoming more common, not less.

The effect on click behavior is well documented. Pew Research Center’s July 2025 study, which tracked browsing activity from a panel of 900 U.S. adults across 68,879 unique Google searches (12,593 of which produced an AI summary), found that users clicked a traditional organic result in just 8% of visits when an AI Overview appeared, compared to 15% when it didn’t, roughly half the click rate. The same study found users were also more likely to end their search session entirely (26% versus 16%) when an AI Overview appeared. Layered on top of that, zero-click searches generally (queries that end without any click at all, AI Overview or otherwise) reached 68% of U.S. Google searches in early 2026 according to SparkToro’s analysis of Similarweb clickstream data, up sharply from about 60% just two years earlier.

What this changes strategically is that ranking #1 is no longer a reliable proxy for traffic. Agencies increasingly weight strategy toward queries where AI Overviews are less dominant (more specific, commercial-intent, and comparison queries tend to see lower AI Overview coverage than broad informational ones), and toward earning citations inside AI-generated answers, not just ranking below them. This is a genuinely new strategic layer that didn’t exist three years ago, and it changes which keywords are worth prioritizing in the first place.

Track Outcomes and Adjust the Mix Continuously

None of the above is a one-time setup. Search behavior, algorithm updates, and competitive activity all shift the relative payoff of each strategy category over time, which is why ongoing measurement isn’t optional. Agencies track rankings, traffic, and conversions against the original strategy to see which levers are actually producing results and which need to be re-weighted. The framework for defining what “success” looks like for a given campaign is covered in our measuring campaign success guide, the specific KPIs tracked month to month are listed in our metrics tracked guide, and how all of this gets sequenced into a phased project plan is covered in our SEO roadmap guide.

How Agencies Decide What to Prioritize First

The order above (technical, then content, then authority, then on-page, then AI-search adaptation) is a general default, not a fixed sequence every campaign follows. A site with strong technical health and a thin content library skips straight to content strategy. A site with great content but almost no external validation gets a heavier early investment in link building and brand mentions. The actual prioritization comes out of the technical and competitive audit conducted at the start of an engagement: whichever category is most constraining current performance gets addressed first, and the rest get phased in behind it. That phasing decision, and how it gets documented into a client-facing plan with milestones, is the specific subject of our SEO roadmap guide.

The Strategic Through-Line

Every category above exists to solve a different constraint: technical work removes barriers, content captures demand, authority signals validate relevance, on-page work clarifies intent to the algorithm, and AI-search adaptation protects against a shrinking click pool. An agency running a real strategy isn’t picking one of these and ignoring the rest, it’s sequencing all of them against what’s actually limiting a specific site’s performance right now, and revisiting that sequence as the search landscape keeps shifting underneath it.
