Frequently Asked Questions
What is the most important SEO factor in 2026?
Topical authority and content relevance have surpassed traditional on-page factors. While meta tags, keyword placement, and technical SEO remain important, search engines now prioritize comprehensive topic coverage, entity relationships, and user engagement signals. Use our Keyword Density Analyzer and Readability Score tools to ensure your content is optimized for both search engines and human readers.
How do Open Graph tags affect SEO?
Open Graph tags do not directly affect search rankings, but they significantly impact click-through rates by controlling how your content appears when shared on social media platforms like Facebook, LinkedIn, Twitter, and messaging apps like WhatsApp and Slack. Higher engagement from social sharing indirectly improves SEO by driving traffic and generating backlinks.
What is a good readability score?
For general web content, a Flesch Reading Ease score of 60-70 (plain English) is recommended. Technical content can score 30-50 (fairly difficult), while content aimed at a broad audience should target 70-80 (fairly easy). The Flesch-Kincaid Grade Level should be around 8th grade for general audiences.
