1. SEO Audit: Comprehensive "medical examination" for the website

An SEO audit, or SEO check, is a comprehensive analysis and evaluation of your website. The main goal is to identify any issues that may negatively impact your SEO performance and then propose solutions to fix them. This process involves checking many aspects, such as:

Technical: Website structure, page load speed, mobile compatibility, indexing, etc.
On-Page : Content, meta tags, URL structure, image optimization, etc.
Off-Page: Backlinks, social media, brand reputation, etc.
So when should you do an SEO Audit?

There are two important times when you should perform an SEO Audit:

When your website shows signs of traffic loss: If you notice an unusual drop in website traffic, an SEO Audit will help you find the cause.
After each Google algorithm update : Google regularly updates its search algorithm. Auditing your website after each update helps you ensure your website complies with the latest guidelines.
