Off-page optimization refers to optimizing a web page or website to improve its ranking in search engine results. This is a part of Search Engine Optimization (SEO) which is done off site. It's not controlled by the page's encoding, unlike overused pages. 

SEO Off-page optimization methods include article submission, directory submission, click-through rate, and inbound links.

Article submission is where articles whose content is related to one web page are published on another article submission site. These can be forums and blogs, and if the site has a high page rank, you can generate inbound links from those pages. 

When a website submits an article, the article must have its own link to that page. Articles must be relevant to the website the article is submitted to to be effective. There are free websites to submit and some high page rankings cost money due to the increasing number of websites using SEO. Articles should contain direct and complete titles as they will appear in search engine results.

CTR, another off-page optimization method, is calculated by tracking followed links in search engine results. A website's CTR increases when a web page includes a short description and professional meta tags, as this information often appears in search engine results. Submitting articles can also increase click density.

Off-page optimization methods carry more weight than on-page optimization, so businesses looking to drive traffic to their websites can use off-page optimization methods to improve search engine rankings.
