How to Use Keywords for SEO the Right Way in 2026

Where Should You Place Keywords on a Web Page?

Place your primary keyword in seven key positions: the title tag, meta description, H1 heading, URL slug, the first 100 words of your content, at least one subheading (H2), and your image alt text. These positions carry the most weight for telling search engines what your page is about, and getting them right is the foundation of solid on-page SEO.

Beyond these core placements, use your primary keyword and secondary keywords naturally throughout your content. The goal is to be clear about your topic without sounding repetitive or forced.

Here is exactly how to optimize each placement for maximum impact.

Title Tag

Your title tag is the single most important keyword placement on any page. Include your primary keyword as close to the beginning as possible. Keep the total title under 60 characters so Google does not truncate it in search results.

Good example: "Plumber SEO Guide: Get More Emergency Calls From Google"

Weak example: "Our Complete Guide to Marketing and SEO Strategies for Plumbing Service Businesses"

The first example leads with the keyword and stays concise. The second buries the keyword and is too long for search results.

Meta Description

While meta descriptions are not a direct ranking factor, they influence click-through rates. Include your primary keyword because Google bolds matching terms in search results, making your listing stand out. Keep descriptions between 140 and 160 characters.

H1 Heading

Your H1 should include your primary keyword and closely match your title tag. Every page should have exactly one H1 tag. This heading is the first thing both users and search engines see when they land on your page.

URL Slug

Include your primary keyword in the URL slug using hyphens between words. Keep URLs short, descriptive, and lowercase. Remove stop words like "the," "and," and "a" to keep URLs clean.

First 100 Words

Search engines give extra weight to content that appears early on the page. Include your primary keyword naturally within the first 100 words of your body content. This also helps readers immediately confirm they have found what they searched for.

Subheadings (H2 and H3)

Use your primary keyword or close variations in at least one or two H2 subheadings. Avoid forcing the exact keyword into every subheading. Use natural variations and related terms to keep the content readable while maintaining keyword relevance.

Image Alt Text

Describe your images using natural language that includes your keyword where relevant. Alt text helps search engines understand image content and improves accessibility. Do not stuff keywords into every image alt tag. Only include them when the keyword genuinely describes the image.

How Many Keywords Should You Target Per Page?

Target one primary keyword and two to four secondary keywords per page. This gives search engines a clear signal about your page's main topic while allowing you to rank for related searches. Trying to target too many unrelated keywords on a single page dilutes your relevance and makes it harder to rank for any of them.

Primary keyword: The main topic and search query you want this page to rank for. Every content decision on the page should support this keyword.

Secondary keywords: Related terms, synonyms, long-tail variations, and semantically connected phrases. These support your primary keyword and help you capture additional search traffic.

Example for a plumber SEO page:

Each secondary keyword should be closely related to the primary keyword. If a secondary keyword represents a completely different topic, it deserves its own dedicated page.

What Are Secondary Keywords and How Do You Use Them?

Secondary keywords are related terms, synonyms, and variations that support your primary keyword and help search engines understand the full scope of your content. They are sometimes called supporting keywords, LSI keywords, or semantic keywords.

Google's algorithm understands relationships between words and concepts. When you include secondary keywords naturally throughout your content, you demonstrate topical depth and relevance. This helps your page rank for a wider range of related searches, not just your exact primary keyword.

How to Find Secondary Keywords

Start by searching your primary keyword on Google and noting the related searches at the bottom of the results page. Also look at the "People also ask" boxes for question-based secondary keywords.

Free tools like Ubersuggest and Google Keyword Planner suggest related keywords automatically. Look for terms that share the same search intent as your primary keyword but use different wording.

How to Use Secondary Keywords Naturally

Scatter secondary keywords throughout your content in places where they fit naturally. Good locations include:

The key is natural integration. If you have to restructure a sentence awkwardly to include a keyword, skip it. Google's algorithm is sophisticated enough to understand your topic from context and related terms.

How Many Keywords Should a Website Have in Total?

A website can realistically target hundreds or even thousands of keywords, but each individual page should focus on one primary keyword and a few secondary keywords. The total number of keywords your site targets depends on how many pages you create and how many distinct topics your business covers.

Small local business website (10 to 20 pages): Might target 50 to 100 keywords across service pages, location pages, and blog posts.

Medium business website (50 to 100 pages): Could target 200 to 500 keywords with dedicated pages for each service, location, and informational topic.

Large content site (hundreds of pages): Can target thousands of keywords through comprehensive blog content, guides, and resource pages.

The right approach is to identify all the keywords relevant to your business, group them into topic clusters, and create one focused page per cluster. Our local SEO checklist covers how to structure your website's keyword targeting for maximum coverage without cannibalization.

What Is Keyword Stuffing and How Do You Avoid It?

Keyword stuffing is the practice of overloading a page with keywords in an attempt to manipulate search rankings. Google penalizes this behavior because it creates a poor experience for readers.

Examples of keyword stuffing:

How to avoid it: Write for humans first. If your content sounds natural when you read it out loud, your keyword usage is probably fine. A good rule of thumb is that if a keyword feels forced or repetitive, remove it or use a variation instead.

Modern SEO is about demonstrating expertise on a topic, not about hitting a magic keyword density number. Google's natural language processing is advanced enough to understand your topic from context, synonyms, and related concepts.

How Do Keywords Work Differently for Local SEO?

Local SEO adds geographic modifiers to your keyword strategy. Instead of just targeting "plumber," a local business targets "plumber in Dallas" or "emergency plumber near me."

Key differences for local keyword strategy:

Location-based keywords: Add your city, neighborhood, county, or service area to your primary keywords. Create separate pages for each major service area you cover.

"Near me" keywords: Google handles "near me" searches based on the searcher's location, not your page content. You do not need to put "near me" in your content. Instead, make sure Google knows where you are located through your Google Business Profile and local citations. Our Google Business Profile optimization guide covers this in detail.

Service plus location combinations: Create dedicated pages for each service-plus-location combination that has meaningful search volume. A plumber serving three cities might have separate pages for "plumber Dallas," "plumber Fort Worth," and "plumber Arlington."

Local intent keywords: Some keywords have implicit local intent even without a location modifier. "Emergency plumber" and "AC repair" almost always show local results because Google knows searchers want a nearby provider.

How Has Keyword Optimization Changed With AI Search?

AI-powered search features like Google's AI Overviews have changed how keywords work in practice. These AI summaries pull information from pages that directly and concisely answer questions, making it more important than ever to structure your content clearly.

What works now:

What matters less:

The shift is toward answering questions thoroughly and clearly rather than optimizing for specific keyword strings. A well-structured page that comprehensively covers a topic will outperform a page that is technically optimized but thin on substance.
