A website audit is a comprehensive analysis of your site's SEO health, performance, mobile-friendliness, and security. Regular audits help identify issues that hurt your search rankings, user experience, and conversion rates. Studies show that 75% of users judge a company's credibility based on its website design and performance.

Experts recommend performing a full SEO audit at least once every quarter. However, for larger websites or those in competitive niches, monthly audits are ideal. Additionally, you should run a quick audit after any major site update, redesign, or Google algorithm change to ensure nothing has broken.

The most critical on-page SEO factors include: title tags (optimal length 50-60 characters), meta descriptions (120-160 characters), proper heading hierarchy (one H1 per page), image alt text for accessibility and image search, canonical URLs to prevent duplicate content, and mobile responsiveness. Google also considers page speed and HTTPS as ranking signals.

Page speed is a confirmed Google ranking factor, especially with Core Web Vitals. Slow-loading pages increase bounce rates—47% of users expect a page to load within 2 seconds, and 40% abandon sites taking over 3 seconds. Faster sites provide better user experience, leading to higher engagement, lower bounce rates, and improved rankings.

Google uses mobile-first indexing, meaning it primarily uses the mobile version of your site for ranking. Over 60% of all searches now come from mobile devices. A mobile-friendly site with proper viewport meta tags, responsive design, and touch-friendly navigation is essential for both rankings and user experience.

Open Graph (OG) tags are meta tags that control how your content appears when shared on social media platforms like Facebook, LinkedIn, and Twitter. They define the title, description, image, and URL preview. Without OG tags, social platforms auto-generate previews, often resulting in unattractive or incorrect snippets that reduce click-through rates.

A canonical URL (specified via <link rel="canonical">) tells search engines which version of a page is the "master" copy when duplicate or similar content exists across multiple URLs. Use canonical tags to consolidate ranking signals and prevent duplicate content penalties, especially for e-commerce product pages with filter parameters or pagination.

HTTPS is a confirmed Google ranking signal since 2014. Sites without SSL certificates are marked as "Not Secure" by browsers, which can deter visitors and increase bounce rates. HTTPS encrypts data between the user and server, building trust. Google Chrome actively warns users about insecure HTTP pages, making SSL essential for both SEO and credibility.
