The documents emphasize the importance of monitoring performance using tools like Google Search Console and Google Analytics, and suggest a phased approach to implementation, starting with basic setup and progressing to more advanced strategies. The checklists offer a framework for reviewing existing websites or planning new ones, with a focus on actionable checkpoints.

SEO Basics Checklist

The foundation of a successful SEO strategy involves establishing key tools and monitoring performance. According to the source materials, setting up Google Search Console is a critical first step. Google Search Console provides access to tools and reports for optimizing websites on Google Search. Businesses should also utilize Google Analytics to measure SEO performance and understand how users interact with their site. The data indicates that monitoring SEO performance and adjusting strategy based on data insights is essential for success.

Keyword Research Checklist

Effective keyword research is presented as a core component of SEO. The process begins with brainstorming to identify core and related keywords relevant to the business. This initial list should include terms related to the company, industry, and location. The materials suggest assessing the value and rankings of identified keywords, analyzing search intent, and checking for keyword cannibalization. A keyword map should then be built to organize and prioritize keyword targeting. One source suggests starting with keywords like “vintage t-shirts in [city]” or “electricians in [city]” as examples.

Technical SEO Checklist

Technical SEO focuses on ensuring a website is easily crawlable and indexable by search engines. The checklists highlight the importance of optimizing Largest Contentful Paint (LCP) to 2.5 seconds or less, Cumulative Layout Shift (CLS) to 0.1 or less, and Interaction to Next Paint (INP) to 200ms or less. Ensuring a secure connection (HTTPS) and a properly configured robots.txt file are also noted. The materials recommend checking different URL versions to avoid duplicate content issues. Utilizing tools like SEOcrawl in conjunction with Search Console is suggested for more in-depth analysis.

On-Page Optimization Checklist

On-page optimization involves optimizing individual web pages to rank higher in search results. The source materials emphasize the importance of targeting one primary keyword per page, supported by related secondary keywords. Keywords should be used semantically and incorporated into the URL, meta title, and meta description. The meta description should be between 150 and 160 characters, be unique for each page, address customer problems, present a solution, and highlight the outcome.

Website Feature Checklist

One source provides a broader website checklist encompassing elements beyond SEO. This checklist is divided into sections focused on attracting visitors, making a good first impression, building trust, and driving sales. Within the “Get Traffic to Your Website” section, organic search is highlighted, with keyword optimization as a key component.

Utilizing Google Tools

Multiple sources emphasize the importance of Google Search Console and Google Analytics. Google Search Console is described as an essential platform for gaining insights into website performance in Google Search, including performance metrics and updates regarding site issues. Google Analytics is presented as the tool for measuring the effectiveness of SEO efforts. Both tools are free and directly provided by Google.

Mobile SEO Checklist

Optimizing for mobile devices is presented as a crucial aspect of SEO. The checklists recommend ensuring the website provides a positive mobile page experience, including a secure connection, the absence of intrusive interstitials or mobile popups, and easily distinguishable content from advertisements. The content should also be visually appealing and easy to read on mobile devices.

Ongoing SEO Checklist

The source materials suggest that SEO is not a one-time task but an ongoing process. While specific details of an ongoing checklist are not fully elaborated, the emphasis on monitoring performance and adjusting strategy implies a need for continuous optimization and adaptation.
