What is the ideal frequency for publishing articles and what should be the length of these articles for a website's SEO?

The number of blog posts recommended for SEO doesn't have a one-size-fits-all answer, but there are some general guidelines and best practices to consider:

1. Consistency Over Quantity:

- Regular Posting: It's better to post consistently rather than just focusing on the number of posts. For many businesses, posting once or twice a week is a good benchmark. However, even if you post less frequently, ensure that you do so regularly (e.g., once a month).

2. Quality Over Quantity:

- High-Quality Content: High-quality, informative, and engaging content is far more important than just publishing a high volume of posts. Google's algorithms favor content that provides value to the user.

- In-depth Posts: Longer, more detailed posts (1,500-2,500 words) often perform better in search rankings, as they tend to cover topics more thoroughly.

3. Optimal Frequency:

- Small to Medium Blogs: For small businesses or personal blogs, 1-2 posts per week is a solid frequency. Over a year, this would amount to around 50-100 posts.

- Larger Blogs/Media Sites: For larger blogs or news-oriented sites, posting more frequently—daily or even multiple times a day—might be necessary to stay competitive.

4. Long-Term Goals:

- Authority Building: If your goal is to build a significant online presence, aim for at least 100-200 high-quality posts over time. This level of content can help establish your site as an authority in its niche.

- Sustained Growth: The impact of content on SEO is cumulative. The more content you have (assuming it's high quality), the more opportunities you have to rank for different keywords and attract traffic.

5. Keyword Strategy:

- Diverse Keyword Coverage: More blog posts allow you to target a broader range of keywords. However, ensure each post is focused on specific, relevant keywords to avoid keyword cannibalization.

6. Monitoring and Adjusting:

- Analyze Performance: Regularly monitor the performance of your content and adjust your strategy accordingly. If you notice that certain types of posts perform better, focus more on those.

A consistent and quality-driven approach with a goal of steadily increasing the number of posts over time is ideal for SEO. For most blogs, aiming for 1-2 posts per week is a good starting point, with an eye toward producing 100+ posts over time for significant SEO benefits.
