Frequently asked questions

What does the SEO Content Checker analyze?

Title length and keyword inclusion, meta description quality, keyword density and placement, readability, and content length guidance.

What is a good keyword density?

Aim for ≈0.5–2.5% with natural, varied phrasing. Avoid stuffing.

How much content should I write?

Write enough to satisfy intent; many educational pages land between 800–1200 words.

Will this change my layout?

No. It only optimizes the underlying logic and guidance; UI remains unchanged.

Can I use this with WordPress?

Yes. Use the guidance to edit titles, meta descriptions, and content directly in your editor.

What's the ideal keyword density for SEO?

Aim for 1-2% primary keyword density for most content types. However, density matters less than placement and semantic coverage. A keyword appearing naturally 8-12 times in a 1,000-word article with proper placement (title, first paragraph, headings) often outperforms the same keyword appearing 20 times scattered randomly. Focus on natural language that serves readers first — Google's algorithms detect forced keyword repetition and can penalize it.

How do semantic keywords improve rankings?

Semantic keywords are terms topically related to your primary keyword that help search engines understand your content's comprehensive coverage. Google uses semantic analysis to evaluate whether your content genuinely covers a topic or merely mentions a keyword. A page about 'dog training' that also discusses 'positive reinforcement,' 'puppy socialization,' and 'obedience commands' signals deeper topical expertise than a page that only repeats 'dog training' throughout.

What is content gap analysis and why does it matter?

Content gap analysis compares your content against top-ranking competitors to identify subtopics, questions, and concepts they cover that you don't. Google rewards comprehensive content that addresses the full scope of user intent. If 9 of 10 top-ranking pages for 'email marketing' include a section on deliverability and your page doesn't, Google may interpret your content as less comprehensive. Gap analysis reveals exactly which topics to add to match or exceed competitor coverage.

How often should I update content for SEO?

Review high-traffic content quarterly for freshness and competitive positioning. Update annually at minimum for evergreen content. For time-sensitive topics like statistics, trends, or year-specific advice, update more frequently. Content refreshes often produce significant ranking improvements because they signal to Google that your page remains current and maintained. When updating, focus on adding new subtopics, refreshing statistics, and addressing new questions in People Also Ask boxes.
