Frequently Asked Questions

On-page SEO covers everything you control on a page: title tag, meta description, heading hierarchy, content depth and uniqueness, internal links, image alt text, and URL structure. It is the foundation of rankings.

Keep title tags between 50 and 60 characters. Above 60 characters, Google truncates the title in search results, which hurts click-through rate.

Use exactly one H1 per page. The H1 should clearly describe the main topic and ideally contain your primary keyword. Multiple H1s confuse hierarchy and split topic signals.

Meta descriptions are not a direct ranking factor, but they strongly influence click-through rate. A higher CTR signals relevance and indirectly helps rankings.

Match the depth of top-ranking competitors. For most informational queries that is 1,500-2,500 words. For commercial pages, focus on intent fit rather than length.
