The selection of relevant search terms that the user looks for is the starting point of SEO. Google Keyword Planner and Ahrefs assist in determining commonly searched terms.
2. Quality Content
Informative, authentic, and valuable content is ranked high by search engines. Update blogs regularly, write lengthy posts, and make use of multimedia (videos and infographics) to increase ranks.
3. Backlinks
A good backlink profile boosts domain authority and trust. Authority backlinks from high-authority sites indicate that search engines are trustworthy.
4. Mobile Optimization
More than 60% of queries originate from mobile devices. A mobile-friendly site enhances rankings and user experience.
5. Page Speed
Smaller sites enhance user experience and lower bounce rates. Google’s PageSpeed Insights tool can assist in analyzing and optimizing speed.
6. Secure Website (HTTPS)
Google favors secure (SSL-enabled) websites. Sites that lack HTTPS could rank lower in search engine results.
7. User Engagement Metrics
Google looks at user behavior, including:

Bounce Rate – Proportion of visitors who leave a page without engagement.
Dwell Time – Duration spent on a webpage before going back to search results.

1. Prioritize Search Intent
Knowing what the users are searching for (informational, navigational, transactional) aids in producing content that is relevant and ranks higher.
2. Optimize for Featured Snippets
Featured snippets appear at the top of search results, providing direct answers. Structuring content with bullet points, tables, and summaries increases the chances of being featured.
3. Improve Core Web Vitals
Google’s Core Web Vitals measure page speed, responsiveness, and visual stability. Enhancing these factors boosts rankings.
4. Use Structured Data (Schema Markup)
Adding structured data helps search engines understand content better, improving rich results (like star ratings, FAQs, and product details).
5. Take Advantage of Video SEO
Video optimization with correct titles, descriptions, and tags enhances Google and YouTube rankings.
Mistakes to Avoid in SEO
Keyword Stuffing—Keyword overweighting in content may hurt rankings.
Duplicate Content—Duplicate content is penalized by search engines, so use unique content.
Ignoring Mobile Optimization—A mobile-unfriendly website misses ranking potential.
Slow Page Speed—Users abandon slow sites, raising bounce rates.
Lack of Internal Linking—Internal links assist search engines in finding and ranking pages.
