On-page SEO refers to optimization efforts focused on the content and HTML source code of individual web pages. It allows you to ensure search engines can properly crawl, index, and understand the content on each page of your website to serve relevant search results.
While other factors like backlinks impact search rankings as well, optimizing your internal web pages provides the foundation for strong search visibility and traffic.
This complete on-page SEO checklist will walk through all of the essential elements to optimize.
Why On-Page SEO Matters
Solid on-page SEO leads to:
✅ Higher rankings for targeted keywords
✅ Increased organic traffic to your site
✅ More conversions and revenue
Without proper on-page optimization, your content stands little chance of outranking the competition or attracting substantial search traffic.
For example, weak page titles and meta descriptions lead to much lower click-through rates (CTRs) from search engine results pages (SERPs). Technical errors like site speed issues or improper HTML markup prevent proper indexing.
Optimizing page content readability, multimedia elements, and structure also keeps visitors engaged once they land on your pages. This further encourages sharing or backlinks.

Keyword Optimization
Thorough keyword research and analysis informs your entire content strategy and on-page optimization approach.
You want to identify and target primary keywords along with relevant secondary terms that align with your brand and cover searcher intent.
Target Primary & Secondary Keywords
Start by using keyword research tools to uncover:
- High-volume terms driving large search volumes
- Long-tail variants honing in on subtopics
- Location-based keywords factoring in geographic interest
- Related questions searchers ask
Example primary keywords could be:
- SEO basics
- Content marketing strategy
While secondary terms help expand reach:
- Local SEO company
- Types of online content
Next, assess searcher intent and purpose for each keyword, especially around:
✅ Informational queries looking for guides, tips, etc.
✅ Transactional searches focused on making a purchase
✅ Navigational searches trying to access a specific site
This ensures you target terms matching the purpose of each page.
An effective approach is to cluster topically related keywords around:
- Specific content offers (guides, tools, etc.)
- Location pages (city or neighborhood landing pages)
- Key conversion pages (pricing, contact, etc.)
Strategic Keyword Placement
With your core terms identified, work them strategically throughout page content in these elements:
Headings: Use your primary keyword in the H1 heading, then secondary terms in H2/H3 tags
First 100 words: Front-load key phrases high on the page
Keyword placement tips:
- In the opening paragraph
- Breaking up large blocks of text
- Next to relevant images
- In emphasized text like bold or italics
Body content: Include variants and LSI terminology
Page URL: Format using keywords when possible
Avoid Keyword Stuffing
While keyword usage is critical, be careful not to over-optimize pages. Jamming terms throughout content where it flows unnaturally leads to a negative user experience.
Follow these keyword density best practices:
- Primary keyword density: 1-2%
- Secondary terms density: 0.5-1%
- Key phrases used: 4-5 times ideally
Also mix keyword placement throughout sections rather than repeatedly:
❌ Keyword used 10+ times in the introduction
✅ Terms spaced evenly in headings, body content, etc.
Check that reading flows naturally and page doesn’t feel spammy.
Title Tags & Meta Descriptions
Title tags and meta descriptions preview page content on SERPs, enticing searchers to click through. Craft compelling versions optimized with keywords.
Create Engaging Title Tags
Page titles serve the dual goals of accurately summarizing content while intriguing visitors to click from search listings.
🚫 Avoid: URLS or generic names like “Home” or “Blog”
✅ Do: Incorporate primary keyword and key brand terms
Ideally build titles around this structure:
Primary Keyword – Secondary Term | Brand Name
Some title tag examples:
🌟 Content Marketing Strategy Guide | ACME Co.
🌟 Local SEO Checklist for 2023 | ACME Co. Phoenix
General title tag guidelines:
- Length: 55-60 characters
- Position keyword toward the beginning
- Provide key context afterward
Write Strong Meta Descriptions
Meta descriptions summarize page content in 155-160 characters.
❌ Avoid: Duplicate, vague, or overly promotional language
Craft compelling descriptions like:
✅ Do: Highlight key topics, numbers, or persuasive words
While aligned with page content, meta descriptions help convince searchers to click on a listing through:
- Using emotional hooks or questions
- Listing benefits of the content
- Including facts or statistics
Follow meta description tips:
- Feature primary and secondary keywords
- Keep around 155-160 characters in length
- Entice clicks with compelling writing
URL Structure
Optimizing your page URLs impacts not only SEO but overall site structure and navigation as well.
Create SEO-Friendly Permalinks
Dynamic URLs with messy query strings and parameters hamper both user experience and search visibility.
Instead implement cleaner permalinks like:
✅ https://www.website.com/keyword-focused-page-slug
CMS platforms like WordPress or custom coding allow you to reformat URLs. Common structures include:
/category/subcategory/specific-page/yyyy/mm/dd/blog-post-title
Tips for perfecting URLs:
- Feature primary page keyword early
- Separate words using dashes or underscores
- Avoid excessive length if possible
Manage Redirects
When URLs change or pages move, properly redirect old addresses to new destinations. This maintains link equity and prevents broken links.
Key redirect guidelines per HTTP response codes:
- 301 permanent redirect: preferred for all URL shifts
- 302 temporary redirect: short-term only
Check redirect chains to avoid looping or slow redirects across multiple pages.
For managing redirects at scale, robust CMS capabilities or plugins like Redirection are invaluable.
Content Quality & Structure
With keywords targeted throughout, ensure content itself flows well and keeps visitors engaged.
Craft Engaging Page Content
Beyond keyword usage, your actual page content must deliver substantive value for readers.
Make content:
❌ Avoid thin, duplicate, or low-quality content
✅ Do create in-depth, accurate content providing unique insights
Specific elements to include based on content type:
Blog Posts: Personal experiences, embedded media, comments/shares
eBooks / Guides: Statistics, expert perspectives, case studies
Service / Product Pages: Benefits, ROI examples, customer stories
Check that content reads smoothly and makes logical sense from start to finish.
Use Proper Header Tags
Break up large blocks of content with properly structured header tags. This enhances on-page SEO along with readability.
🔽 Heading hierarchy 🔽
H1: Primary page keyword target
H2: Secondary keywords/subtopics
H3-H6: Related keywords/details
Formatting header tags in your CMS or with HTML allows proper indexing and bolding of rankings on SERPs.
Mix header sizes breaking up content rather than using H2 and H3 tags repeatedly.
Incorporate Related LSI Keywords
Latent Semantic Indexing (LSI) looks at the contextual meaning of content rather than matching specific keywords.
Include relevant LSI and related terms throughout content using:
- Industry terminology
- Synonyms and rephrases
- Related topics/questions
Sprinkling these throughout complements your core keywords while reading naturally.
Internal Linking
Links to other pages on your site help search engines crawl new or updated content along with enhancing site navigation.
Develop an Internal Linking Strategy
First map out connections between relevant topics and offers within your site architecture.
❌ Avoid overly broad site-wide links like “click here”.
Then build contextual internal links through:
✅ Do Anchor text using LSI keywords
For example on a content marketing guide, link internally to your services page using “content creation agency” as the anchor text.
Format links opening in new tabs with rel="nofollow" so search engines ignore that specific link, avoiding artificial manipulation of metrics.
Fix Broken Internal Links
Check your site regularly for broken internal links leading to 404 errors. Redirect or remove damaged links.
For ongoing link audits at scale, try broken link checker software to identify issues automatically.
External Linking
While internal navigation matters, relevant external resources also validate your expertise and content to search engines.
Reference Trusted External Sources
Link out sparingly to quality external websites. This helps establish subject-matter authority.
💡 Choose sites like:
- Industry publications
- Notable influencers
- Relevant research reports
Cite reference links naturally within content using anchor text aligning with the source rather than generic terms.
Track and Manage Lost Backlinks
Just as you link out to others, monitor backlinks pointing to your domain as well.
If an external webpage you previously linked to removes or changes that link, directly request adding it back. Use open web page signifiers in case the source is paywalled or requires login access.
Proactively fixing lost backlinks maintains your overall domain authority and organic growth velocity, especially if from notable providers.
Multimedia Optimization
Visually engaging images, videos, graphics and other media within your content boosts overall user experience. Optimize multimedia both technically and using keyword-focused descriptions.
Properly Tag and Compress Images
Enable image crawlability with core technical components:
Descriptive file names: guide-to-content-marketing-strategy.png
Alt text: Describes the image visually using target key phrase plus descriptive context. Keep under 125 characters.
Compression: Reduce file size without losing quality using TinyPNG or tools within WordPress etc.
Dimension sizing: Scale images appropriately so pages load quickly on all devices
⛔️ Avoid generic file names like image.jpg or overly lengthy alt text.
Optimize Your Video Content
Video content allows both embedding within pages along with YouTube distribution.
Key video optimization components:
File names/URLs: Descriptive using primary and secondary keywords
Title & description: Clearly summarizes content
Closed captioning: Enhances accessibility and SEO if readable captions provided
Transcripts: Can improve rankings and snippets for informational queries
Upload natively if bandwidth allows or use YouTube as well.
Enhance User Engagement
Compliment written content using graphics, polls, quizzes and interactive content when possible to further captivate visitors.
❌ Avoid excessive popups, overlays or widgets disrupting reading flow.
Measure user engagement levels with multimedia and reduce accordingly if high exit rates.
Technical SEO Factors
Like building a house, core website infrastructure impacts SEO results and user experience.
Improve Site Speed
With <a href=’https://www.thinkwithgoogle.com/consumer-insights/consumer-trends/mobile-site-speed-new-industry-benchmarks/’ rel=’nofollow’>53% of mobile site visitors</a> abandoning pages taking over 3 seconds to load, speed is a ranking factor and UX essential.
❌ Avoid scale image files, complex code, or too many plugins slowing things down.
✅ Do optimize and compress images, minify code, and enable compression via tools like Cloudflare.
Test site speed using PageSpeed Insights and GTmetrix, aiming for scores over 90/100 on mobile and desktop.
Ensure Mobile-Friendly Pages
With 60% of web traffic coming from smartphones globally, mobile responsiveness is vital.
Key elements:
- Resizing imagery and fonts
- Adaptive information architecture
- Eliminating horizontal scrolling
- Tap-friendly links and buttons
Confirm mobile readiness via Google’s Mobile-Friendly Test.
Submit XML Sitemaps
Sitemaps outline all pages on your site for more efficient crawling and indexing.
Given the scale of sites now, manual submissions are ineffective. Most CMS platforms can auto-generate and submit XML sitemaps instead.
Validate your sitemaps at tools like XML-Sitemaps.com to catch any errors blocking submissions.
UX Enhancements
With content and pages now fully optimized, further website enhancements centered around user experience helps encourage engagement and conversions.
Streamline Site Navigation
Cluttered menus, hidden pages, and confusing site architecture harms user experience.
👎🏻 Avoid excessive top-level navigation links
Guide visitors with clear internal linking and organization like:
👍🏻 Do logical site segmentation
👍🏻 consistent footer linking
👍🏻 contextual related posts
Measure most visited pages and common flows using analytics to optimize information architecture.
Install Breadcrumb Navigation
Displaying page breadcrumbs like “Home > Content Marketing > Strategy Guide” improves wayfinding context.
Easily add via SEO plugins or structured data markup.
Prominent Calls-To-Action
Calls-to-action (CTAs) encourage conversions but often blend in.
❌ Avoid buried or passive CTAs
Draw attention with design contrast like:
✅ buttons over text links
✅ bright colors
✅ clear descriptive text
Scroll heatmaps demonstrate where readers focus most to place key CTAs appropriately.
Schema Markup for SERPs
Provide structured data on your pages allowing search engines to generate rich result snippets.
Implement Schema Markup
Go beyond basic metadata by tagging content types through schema.org standards like:
📰 Articles: Markup key details like headline, date published, author etc. Enables rich snippets.
📷 Image Schema: Allows image galleries or 360-degree views in the SERPs
📝 FAQ Schema: Tags questions and answers together for featured SERP panels
WordPress plugins add schemas easily. For custom coding, use JSON-LD or Microdata formats. Measure success in SERP features and test different schemas to maximize snippets.
Regular SEO Audits & Updating
Ongoing optimization and iteration ensures changes from Google updates are addressed promptly.
Perform Routine Content Audits
Revisit your site pages every quarter to check:
- Title tags and meta descriptions
- Image alt text
- Broken internal links
- Any content needing refreshing
Build an editorial calendar for updating underperforming pages and publishing net new content based on opportunities identified through analytics and rankings.
Check for Algorithm Updates
Monitor algorithm change trackers like Mozcast for Google updates impacting rankings.
Reevaluate affected pages to identify any new optimization needs or fixes for declines.
