It's highly unlikely to rank a new keyword on the first page of Google within just 5 days, as it takes time and effort to build authority and relevance for a specific keyword. However, there are a few strategies that you can use to improve your chances of ranking for a keyword in a relatively short amount of time:

Optimize your on-page SEO: Ensure that your website and individual pages are optimized for the target keyword. Use the keyword in the title tag, meta description, URL, and header tags (H1, H2, etc.), and make sure the content is relevant and high-quality.

Build backlinks: Backlinks are an important factor in SEO, and they can help improve your ranking for a specific keyword. Reach out to other websites in your niche and ask them to link back to your content. Share your content on social media and other relevant platforms to increase visibility and attract more backlinks.

Use long-tail keywords: Targeting long-tail keywords (i.e., longer, more specific phrases) can be easier to rank for than shorter, more competitive keywords. Focus on long-tail keywords that are highly relevant to your business and have a decent search volume.

Utilize Google My Business: If you have a local business, make sure your Google My Business listing is optimized for your target keyword. This can help improve your visibility in local search results.

Use paid advertising: While organic SEO takes time to see results, paid advertising such as Google Ads or social media ads can help get your content in front of a wider audience in a shorter amount of time. However, this can be a costly strategy and should be used with caution.

Remember, SEO is a long-term strategy, and it can take several months to see significant results. Focus on creating high-quality content that is optimized for your target keywords, building backlinks, and engaging with your audience to improve your overall online presence.
