-
What is an on-page in SEO?
On-page SEO, also called on-site SEO, is a type of search engine optimization that focuses on optimizing web pages to improve a website’s search engine performance in relevant search results. It also involves improving or enhancing key elements such as website content, HTML elements, page speed, and website structures to help websites become more readable, relevant, and valuable for browsers.
-
What is the difference between technical SEO and on-page SEO?
Firstly, both on-page and technical SEOs are part of every effective SEO strategy; what differentiates them are their focus and methodologies. On-page SEO works on optimizing individual page content and elements like title tags, keyword placement, and internal linking. It ensures content is optimized for maximum readability and relevance to browsers. On the other hand, technical SEO prioritizes enhancing the technical aspects of a website to improve its overall technical performance, like indexing and crawling. It works on maximizing site speed, improving mobile responsiveness, and fixing crawl errors. When combined together, on-page and technical SEO can supercharge any SEO strategy.
-
How much does on-site SEO cost?
The cost of on-site SEO will depend on several factors, such as the scale of the project, the current state of the website, and what type it is — if it’s going to be a one-time or ongoing project. Typically, when hiring a dedicated on-site SEO agency for comprehensive on-page optimization, the cost can range from $1,000 – $10,000. However, for larger-scale projects, the price tag can go as high as $20,000 – $50,000.
