The term “on-page SEO” refers to actions taken by the SEO company in London to improve the integrity and performance of a website, such as:

• Ensuring meta tags, title tags and headers contain keywords.
• Ensuring the website loads quickly.
• Making sure the site is mobile-friendly (extremely important).
• Eliminating duplicate content.
• Cleaning up the backend coding.
• Making sure all images are optimised and have “alt” tags.
• Replacing poorly written content.

How a website performs for visitors is an important factor Google uses to help them determine if a website is worthy of a high ranking in search results. So on-page SEO is actually very important.
