SEO Best Practices for Content Writing
Creating content that ranks well on Google requires more than just inserting keywords. Here are the key on-page SEO best practices this tool helps you implement:
- Keyword placement: Include your target keyword in the title, meta description, first paragraph, and at least one heading (H1 or H2). Maintain a keyword density between 0.5% and 2.5%.
- Content length: Longer content tends to rank better. Aim for at least 1,000 words for informational content and 1,500+ for competitive keywords.
- Heading structure: Use one H1 tag per page, followed by H2s for main sections and H3s for subsections. This helps search engines understand your content hierarchy.
- Readability: Write for humans first. Keep sentences under 20 words when possible, use active voice, and include transition words for better flow. Aim for a Flesch Reading Ease score of 60+.
- Internal and external links: Link to relevant pages on your own site (internal) and authoritative external sources. Use nofollow for sponsored or affiliate links.
- Meta description: Write a compelling meta description between 120-160 characters that includes your keyword and encourages clicks from search results.
Understanding the SEO Score
Our SEO scoring system evaluates your content across five categories, each contributing to a total score out of 100:
- Keyword (25 points): Checks if your keyword appears in the content, title, meta, first paragraph, and headings, plus whether the density is in the ideal range.
- Content (20 points): Evaluates word count milestones — 300, 600, 1,000, and 1,500+ words earn progressively more points.
- Structure (20 points): Validates your heading hierarchy, paragraph count, and use of transition words for content flow.
- Readability (20 points): Assesses Flesch score, long sentence count, passive voice usage, and paragraph length for reader-friendliness.
- Meta (15 points): Checks title and meta description length, and whether your keyword appears in both.
Dofollow vs Nofollow Links: When to Use Each
Understanding link attributes is crucial for SEO. Our tool makes it easy to insert both types with keyboard shortcuts:
- Dofollow links (default) pass "link juice" — SEO value — to the linked page. Use these for authoritative sources, internal links, and references you want to endorse.
- Nofollow links (rel="nofollow") tell search engines not to pass ranking value. Use these for affiliate links, sponsored content, user-generated content, and links to sites you don't want to endorse.
- Sponsored links (rel="sponsored") are specifically for paid placements, advertisements, and affiliate links. Google recommends this over generic nofollow for paid links.
- UGC links (rel="ugc") are for user-generated content like comments and forum posts.
