02Questions
Frequently asked.
What are meta tags and why do they matter for SEO?
+Meta tags are HTML elements that provide metadata about a page to search engines and social platforms. The most important are the title tag and meta description, which directly influence how your page appears in search results. Title tags are a confirmed Google ranking factor, and compelling meta descriptions improve click-through rates. Other meta tags like canonical, robots, and viewport affect indexing, crawling, and mobile usability.
What is the ideal title tag length?
+Google typically displays the first 50 to 60 characters of a title tag in search results. Keep titles under 60 characters to avoid truncation. Google actually measures pixel width, so titles with many wide characters may be truncated sooner. Place your primary keyword near the beginning and make the title compelling.
How long should a meta description be?
+Meta descriptions should be 70 to 160 characters. Google may display up to 155 to 160 characters on desktop and slightly fewer on mobile. Descriptions too short waste space; too long get truncated. Include your target keyword naturally and write a compelling call to action.
What is a canonical tag and when should I use one?
+A canonical tag (rel="canonical") tells search engines which version of a page is the primary version. Use it when you have duplicate or similar content at multiple URLs (parameters, HTTP vs HTTPS, www vs non-www). It consolidates link equity and ranking signals to a single URL.
What are Open Graph tags and do they affect SEO?
+Open Graph tags (og:title, og:description, og:image) control how your page appears when shared on Facebook, LinkedIn, and other social platforms. Not a direct Google ranking factor, but they significantly impact social sharing behavior and referral traffic.
What is the viewport meta tag and why is it important?
+The viewport meta tag controls how a page is displayed on mobile devices. The standard setting (width=device-width, initial-scale=1) tells the browser to match the screen width. Without it, mobile browsers render pages at desktop width and then scale down. Since Google uses mobile-first indexing, a missing viewport tag can hurt both user experience and search rankings.
