On-Page SEO Optimization: Tips to Make Your Website Stand Out on Google
On-Page SEO Optimization: Tips to Make Your Website Stand Out on Google
On-Page SEO gives you 100% control — unlike Off-Page SEO which depends on external backlinks. Correct on-page optimization is the foundation that amplifies every other SEO effort's effectiveness.
Title Tag: The Most Important 60 Characters on Your Page
Title tags appear in browser tabs and Google search results. They are among Google's highest-weighted on-page ranking factors.
Writing effective title tags: place the primary keyword first, stay within 60 characters (or 600 pixels), add the brand name at the end with a separator like "|", and write to attract clicks, not just to insert keywords.
Strong example: "วิธีทำ AEO สำหรับ SME ไทย — คู่มือฉบับสมบูรณ์ | TecTony"
Meta Description: Free Advertising in Google's SERPs
Meta descriptions don't directly influence rankings, but they significantly affect CTR. A compelling meta description drives more clicks, which sends positive signals to Google.
Write meta descriptions that: run 140-155 characters, naturally include the primary keyword, clearly state the benefit to the reader, and include a CTA like "อ่านเพิ่มเติม" or "เรียนรู้เลย."
Header Tags (H1-H6): Structure That Google Can Read
Each page needs exactly one H1 tag containing the primary keyword. The difference between H1 and the title tag: the title appears in SERPs, the H1 appears on the page. They should be similar but don't need to be identical.
Use H2 for major content sections, incorporating secondary keywords and related questions. Use H3 for sub-sections within each H2. Never use header tags for visual styling — use CSS instead.
URL Structure: Clean and Keyword-Rich
Good SEO URLs are: short, keyword-containing, hyphenated (not underscored), entirely lowercase, and free of unnecessary stop words.
Strong example: /blog/aeo-sme-thailand/
Poor examples: /p=123 or /blog/วิธีทำ-AEO-สำหรับ-SME-ไทย/
For Thai-language sites, use English transliterations or equivalent English keywords in URLs. Thai characters in URLs get URL-encoded, creating unwieldy-looking strings.
Image Optimization: The SEO Factor Most People Overlook
Every image should have: a descriptive filename (e.g., i-seo-tips.webp not IMG_1234.jpg), natural alt text describing the image and incorporating relevant keywords, WebP format for smaller file sizes, and the loading="lazy" attribute for below-the-fold images.
TL;DR On-Page SEO Checklist
- Title tag: primary keyword first, under 60 characters, brand name at end
- Meta description: 140-155 characters with keyword and CTA
- One H1 per page; H2-H3 for content structure
- Short, clean URLs with English keywords — avoid Thai characters in URLs
- All images need descriptive alt text, good filenames, and WebP format
FAQ
Q: Should I change the title tag of a page that already ranks well?
A: Proceed carefully. Title tag changes can move rankings up or down unpredictably. Only adjust existing strong titles to improve CTR, not as an experiment.
Q: Can Google write its own meta descriptions?
A: Yes, Google often pulls snippets from page content rather than using your meta description. But writing your own still outperforms leaving Google to choose.
Q: Do I need keywords in every H2?
A: No. H2 headings should clearly describe each section naturally. Include keywords when they fit organically — never force them.
Q: Should I change old URLs that aren't optimized?
A: If the URL already has rankings and backlinks, set up a 301 redirect before changing. For new pages with no traffic yet, change freely.
Q: What keyword density should on-page content have?
A: No fixed number. Write naturally, include the primary keyword within the first 100 words, and distribute secondary keywords organically throughout.
