How To Do ON-PAGE SEO in 2025 with Practical Checklist - Beginners Guide
Keyword Research and Usage
Effective keyword research is the backbone of SEO success. In 2025, it requires a mix of data analysis and understanding what users are searching for.
Finding the Right Keywords
Start by identifying the main keywords that represent your business and services. Focus on terms that match user search intent - what your audience is really looking for. A good keyword strategy balances:
Search volume: Choose terms with enough monthly searches to make an impact.
Competition level: Go for keywords where you have a realistic chance of ranking.
User intent: Make sure your keywords align with what searchers want to find.
Long-tail keywords (phrases with 3-5 words) are especially useful for conversions. For instance, "custom kitchen cabinets San Diego" is more specific - and likely more effective - than just "kitchen cabinets."
Once you’ve chosen your keywords, it’s time to use them strategically across your content.
Placing Keywords Correctly
Where you place your keywords matters. To send strong SEO signals, include them in these key areas:
Page title: Within the first 60 characters.
Meta description: Keep it within 155 characters.
H1 heading: Use it once to clearly define the page topic.
First paragraph: Include within the opening 100 words.
Body content: Naturally incorporate every 300-400 words.
Forget about keyword density - it’s outdated. Instead, aim for content that flows naturally while including relevant terms and their variations.
Local Keyword Targeting
If your business serves specific areas, local keyword optimization is a must. Build your strategy around:
City/region + service: Examples like "plumber in Chicago" or "Chicago emergency plumbing."
Neighborhood terms: Such as "Loop Chicago plumber" or "Wicker Park plumbing service."
Nearby landmarks: Phrases like "plumber near Millennium Park" or "plumbing service near Navy Pier."
Use these location-based terms thoughtfully in titles, headers, and throughout your content. This approach helps your business appear in local searches and map results.
For businesses with multiple locations, create individual pages for each service area. Make sure each page has unique content tailored to the specific location. This avoids duplication and boosts visibility in local search results.
Content Writing and Organization
Continuing with our SEO checklist, let’s focus on creating high-quality content and structuring it effectively to improve user engagement and search rankings.
Writing Original Content
Creating content that stands out is key to SEO success. Here’s how to make your content more impactful:
Cover All Bases: Include details like costs, installation steps, maintenance tips, and potential energy savings.
Back It Up: Use original data, case studies, and up-to-date statistics from trusted sources to support your points.
Solve Problems: Address your audience’s specific concerns and provide clear, actionable answers.
This approach ensures your content grabs attention and provides real value.
Making Content Easy to Read
How your content is presented can make or break its effectiveness. Keep these tips in mind:
Keep It Short: Stick to 2-3 sentence paragraphs. Big blocks of text can scare readers away.
Break It Up: Use white space, bold text for key ideas, italics for subtle emphasis, and short sentences (15-20 words on average) to make your content more scannable.
Organize Your Content for Flow:
Introduction: Set the stage with 40–60 words to give readers context.
Main Sections: Use clear subheadings to guide readers through your content.
Supporting Details: Include examples, stats, and concise explanations to back up your points.
Wrap-Up: End with a quick summary of the main takeaways.
Header Tag Structure
Using header tags properly improves both readability and SEO. Here’s the breakdown:
H1 Tag: Use one H1 tag with your primary keyword (e.g., "Complete Guide to Solar Panel Installation").
H2 Tags: Divide your content into major sections, like:
Benefits of Solar Installation
Installation Process Steps
Cost Breakdown
Maintenance Guidelines
H3 Tags: Add subtopics under each H2, such as:
Under "Cost Breakdown":
Equipment Expenses
Labor Costs
Available Tax Incentives
H4-H6 Tags: Use these only when absolutely necessary for deeper layers of organization. Most content works well with just H1-H3.
Technical SEO Basics
These technical elements help search engines understand your content and improve user experience.
Title Tags and Meta Descriptions
Title tags and meta descriptions play a key role in rankings and influencing click-through rates.
Title Tag Best Practices:
Keep titles between 50–60 characters.
Place your primary keyword near the beginning.
Write a title that's both descriptive and engaging.
Add your brand name at the end.
Example: "Solar Panel Installation Guide: Costs & Process | Green Energy Co"
Meta Description Guidelines:
Write compelling copy within 150–160 characters.
Naturally include your main keyword.
Add a clear call-to-action.
Highlight what makes your content stand out.
Example: "Learn expert solar panel installation tips, discover current costs, and uncover energy-saving potential. Get your free consultation today and start saving on your electricity bills."
Clear URL Structure
A clean URL structure helps users and search engines easily understand your content.
URL Format Tips:
Use hyphens (-) to separate words.
Keep URLs short and descriptive.
Include your target keyword.
Leave out unnecessary words like "a", "the", or "and."
Avoid using special characters or numbers.
Bad URL: example.com/p=123?category=solar-energy-installation-guide-and-tips-2025 Good URL: example.com/solar-panel-installation-guide
Once your URLs are optimized, focus on improving visual elements to enhance overall performance.
Image Setup
Choose concise, keyword-focused file names with hyphen-separated words (e.g., solar-panel-installation-process.jpg).
Use JPG for photos, PNG for graphics, or WebP for modern browsers.
Resize images to match the required dimensions.
Add alt text that describes the image and includes relevant keywords.
Alt Text Formula:
Clearly describe the image content.
Add the target keyword when appropriate.
Keep it under 125 characters.
Example alt text: "Professional installing solar panels on residential rooftop during a sunny day"

Website Speed and Usability
Focusing on website speed and usability is a critical part of technical SEO. A site's performance not only affects user experience but also plays a big role in search engine rankings.
Page Speed Optimization
Quick-loading pages improve engagement and can positively influence search rankings. Here's how to enhance page speed:
Server Response Time:
Choose a hosting provider with servers near your audience.
Use server-side caching to reduce load times.
Enable HTTP/2 or HTTP/3 for faster data transfer.
Utilize a content delivery network (CDN) to distribute content efficiently.
Resource Optimization:
Compress CSS, JavaScript, and HTML files to reduce file sizes.
Set up browser caching with proper headers.
Use lazy loading for images and videos to prioritize visible content.
Implement critical CSS rendering for faster page displays.
Clean up unused code and scripts.
Modern Image Formats:
Convert images to WebP format for better compression, with fallback options.
Use responsive images with the srcset attribute for different screen sizes.
Where supported, try AVIF for even smaller image sizes.
Mobile-First Design
With mobile traffic leading the way, designing for smaller screens is non-negotiable.
Mobile Elements:
Build responsive designs that adapt to any screen size.
Ensure touch targets are at least 44x44 pixels for easy interaction.
Use a minimum font size of 16px for readability.
Avoid horizontal scrolling to keep navigation seamless.
