Step-by-step guide to improving on-page SEO with popular CMS plugins - Adil Raseed

In the competitive world of search rankings, your website’s “On-Page SEO” is the foundation upon which everything else is built. While off-page factors like backlinks are essential, your on-page elements are the only things you have 100% control over. If your content is the king, then on-page SEO is the palace—it needs to be structured, accessible, and clearly labeled for the search engine “crawlers” that visit it.

Fortunately, you don’t need to be a coding wizard to master this. Most modern websites run on Content Management Systems (CMS) like WordPress, Shopify, or Wix, all of which offer powerful plugins and apps designed to automate the heavy lifting. This guide provides a step-by-step roadmap to optimizing your site using these popular tools.

1. Choosing Your “Co-Pilot”: The Right Plugin

Before you start optimizing, you need the right tool for your specific CMS. These plugins act as a real-time checklist, grading your work as you write.

For WordPress: Yoast SEO and Rank Math are the undisputed leaders. Rank Math is currently favored for its lightweight code and built-in AI suggestions, while Yoast remains the most beginner-friendly.
For Shopify: SEO Antenna or Plug in SEO are essential for managing product descriptions and “Alt Text” across thousands of SKUs.
For Wix: The built-in Wix SEO Setup Plan is surprisingly robust, though third-party apps like Semrush Writing Assistant can be integrated for deeper insights.

Once installed, these tools sit inside your page editor, providing a “traffic light” system (Red, Amber, Green) to signal your optimization level.

2. Step-by-Step Optimization Workflow

Step 1: Keyword Research and Mapping

Every page should target one primary keyword and 3–5 related “Latent Semantic Indexing” (LSI) terms.

The Action: Enter your primary keyword into your plugin’s “Focus Keyword” box. The plugin will now scan your page specifically to see how well you’ve utilized that phrase.

Step 2: Crafting the Perfect Title Tag and Meta Description

This is your digital billboard. It’s the first thing a user sees on Google.

The Action: In your CMS editor, scroll to the SEO snippet section. Your title should be under 60 characters and include the primary keyword near the beginning. The meta description should be under 160 characters and include a “Call to Action” (CTA) like “Read more,” “Shop now,” or “Get a free quote.”

Step 3: Mastering the Header Hierarchy (H1, H2, H3)

Search engines use headers to understand the structure of your content.

The Action: Ensure you only have one H1 tag (your main title). Use H2s for your main points and H3s for sub-points. Plugins will often flag if you’ve skipped a level (e.g., going from H1 straight to H3), which confuses crawlers.

Step 4: Image Optimization and Alt Text

Google cannot “see” images; it reads the text associated with them.

The Action: Before uploading, rename your image file from IMG_1234.jpg to on-page-seo-guide.jpg. Once uploaded, use your CMS to add Alt Text. Describe the image accurately while incorporating a keyword if it feels natural. This also makes your site accessible to visually impaired users.

Step 5: The URL Slug

Keep your URLs clean and descriptive.

The Action: Instead of yoursite.com/p=123, change it to yoursite.com/on-page-seo-guide. Avoid using years (like 2024 or 2025) in the URL itself so the content stays “evergreen” without needing a URL redirect later.

3. Advanced On-Page Tactics: Readability and Structure

SEO is no longer just about keyword density; it’s about user experience (UX). If users land on your page and immediately leave (a “bounce”), Google will demote your rankings regardless of your keywords.

Sentence Length: Aim for short, punchy sentences. Most plugins will warn you if more than 25% of your sentences are longer than 20 words.
Internal Linking: Link to at least 2–3 other pages on your own site. This keeps users on your site longer and helps Google discover your other content.
External Linking: Link to authoritative, non-competing sites. This shows Google that you have researched your topic and are providing a high-quality resource.

4. The Human Element: Writing for People, Not Bots

While plugins are excellent for technical checks, they cannot judge the “soul” of your writing. A page with a perfect “Green” light from Yoast can still be boring or unhelpful.

The most successful digital marketers balance technical precision with authentic storytelling. As SEO strategist Adil Raseed often points out, “The algorithm is moving closer to the human. If you write content that genuinely solves a problem for a human, the search engine will eventually find a way to reward you.” Use the plugins to fix the “plumbing” of your SEO, but use your unique voice to keep the reader engaged once they arrive.

5. Mobile Optimization: The Non-Negotiable

Since the majority of web traffic now comes from mobile devices, your CMS must be responsive.

The Action: Use your CMS’s “Mobile Preview” mode. Are the buttons too small to click? Is the text large enough to read without zooming? Most SEO plugins now include a check for “Mobile Friendliness,” as this is a core ranking factor for Google.

Frequently Asked Questions (FAQs)

Does a “Green Light” in an SEO plugin guarantee a #1 ranking?

No. A green light simply means you have followed the technical “best practices” for on-page optimization. Ranking #1 also depends on your site’s overall authority (backlinks), site speed, and how your competitors are performing. Think of the plugin as a “minimum requirement” for entry, not a guaranteed win.

How many times should I use my keyword on a page?

There is no “magic number.” Historically, people aimed for a 2% keyword density, but today, “keyword stuffing” will actually get you penalized. Focus on placing the keyword in the Title, the first paragraph, one sub-header, and the URL. Elsewhere, use synonyms and natural variations.

What is the difference between an H1 and a Title Tag?

The Title Tag is what appears on the Search Engine Results Page (SERP) and the browser tab. The H1 tag is the headline the user sees once they are actually on your page. While they can be the same, the Title Tag is usually more “click-focused,” while the H1 is more “content-focused.”

Can I use more than one SEO plugin at a time?

No. This is a common mistake that can significantly slow down your website and cause technical conflicts. Choose one (like Rank Math or Yoast) and stick with it. If you want to switch, most modern plugins have an “Import” feature to move your data over safely.

Why is my meta description not showing up on Google?

Sometimes, Google decides that a different snippet of text from your page is more relevant to the user’s specific search query than the meta description you wrote. Don’t panic; this is normal. However, you should still write custom meta descriptions to give Google the best “suggestion” possible.

Does the length of my blog post matter for SEO?

Quality matters more than quantity, but “thin content” (under 300 words) rarely ranks well for competitive terms. Generally, long-form content (1,200+ words) tends to rank better because it provides more opportunities to cover a topic in-depth and include relevant LSI keywords.

The Path Forward

Improving your on-page SEO is a marathon, not a sprint. By using CMS plugins to create a repeatable workflow, you ensure that every piece of content you publish has the best possible chance of being seen.
