There are four types of SEO: on-page SEO, off-page SEO, technical SEO, and local SEO.
On-page SEO is the process of optimizing a website for Google search with the goal of earning higher web traffic levels and improving the visibility of the site. This can be done by optimizing title tags, meta descriptions, images, and other elements on your website.
Off-page SEO is the process of building backlinks to your website in order to improve its authority and ranking in Google search. This can be done by creating high quality content that other websites will want to link to, as well as through guest blogging and social media outreach.
Technical SEO is the process of ensuring that your website is accessible and easy to crawl for Googlebot. This includes optimizing your site’s structure, code, and sitemap.
Local SEO is the process of optimizing a website for Google search within a specific geographic area. This can be done by claiming your business listing on Google My Business, optimizing your NAP (name, address, phone number) data, and creating location-specific content on your website.
