What is on-page SEO and why does it matter?▾
On-page SEO refers to all optimization factors you control directly on your webpage - title tags, meta descriptions, heading structure, content quality, keyword usage, internal links, and technical elements. On-page SEO accounts for approximately 40% of Google's ranking factors. Optimizing these elements significantly improves your chances of ranking higher in search results.
What does the SEO score mean?▾
The SEO score is a 0-100 rating of your page's on-page optimization across 8 critical factors: title tag, meta description, heading structure, keyword optimization, image alt text, internal links, content length, and mobile signals. A score above 80 means your page is well-optimized for search engines. 60-79 means good optimization with room for improvement. Below 60 means significant opportunities to boost your SEO.
How should I optimize my title tag?▾
Your title tag should be 50-60 characters long, include your primary keyword near the beginning, be unique for each page, and include a compelling reason to click. Example: 'Best Home Automation Systems 2026 | Expert Buyer's Guide' is better than just 'Home Automation'. Title tags appear in search results and browser tabs - make them count.
What is the ideal keyword density for SEO?▾
Modern SEO emphasizes natural keyword usage over density percentages. Aim for your primary keyword to appear 1-2 times per 100 words of content. Secondary keywords can appear more frequently. The most important thing is that keywords fit naturally into your writing - keyword stuffing (repeating a keyword unnaturally) actually hurts your rankings. Google rewards semantic richness and topic coverage over keyword frequency.
Why is heading structure important for SEO?▾
Heading structure (H1, H2, H3) helps search engines understand your content organization and main topics. Best practice: One H1 per page (your main topic), 2-5 H2s (subtopics), and H3s under relevant H2s for detail. This structure also improves readability and user experience. Avoid skipping heading levels (like H1 → H3) as it confuses search engine crawlers.
How many internal links should I have on a page?▾
There's no magic number, but 3-5 relevant internal links per 1000 words is typical. Internal links help search engines crawl your site, distribute page authority, establish information hierarchy, and keep users engaged with related content. Link to high-value pages and use descriptive anchor text (e.g., 'Learn about on-page SEO' instead of 'Click here').
What is image alt text and why does it matter?▾
Alt text (alternative text) describes what an image shows. It helps screen readers assist visually impaired users and helps search engines understand your images for image search rankings. Write concise, descriptive alt text: 'Woman wearing blue running shoes on forest trail' is better than 'woman' or 'shoe'. Include relevant keywords naturally when appropriate, but avoid stuffing.
