Page Titles - Titles play a big role in SERPs so optimize them with your most important keywords while keeping under 70 characters.

Headings - Utilize heading tags H1 to H6 properly to highlight keywords and structure content.

Content - Produce useful, well-researched content focused on target keywords. Naturally incorporate keywords in content.

LSI Keywords - Include latent semantic index (LSI) keywords and synonyms related to your topics to improve relevance. 

Image SEO - Optimize images file names, alt text, etc. with relevant keywords to help search engines understand images.

Site Speed - Fast page speeds enhance user experience and rankings. Keep page size under 2MB and load speed under 2 seconds. Leverage caching, compression and efficient coding.

Navigation Menu - Create an intuitive information architecture and linking structure to related content.

Schema Markup - Use markup on pages to get better CTR and visibility in search, especially for reviews, events, recipes.

Link Analysis - Use Ahrefs and other link analysis tools to monitor your overall link profile and identify risky low-quality links for disavowal.

Local Citations - For local SEO, ensure your business is consistently listed on dozens of local directories, reviews sites and citation sources. Inconsistencies can negatively impact local rankings.

Reviews - Actively generate and manage real customer reviews on your website and other review sites. Reviews build trust and improve local authority.
