Hello, I have few websites. I would like to put my one domain page link on other website on specific keywords. Is this worth? Is this ok? E.g. http://www.xyz.com/page1.html Here I have "computer" keyword, I want to put my other domain page link so user can come directly on my main domain. Is this worth?
YES of course just make sure the link on your other sites comes from a page with content relevant to your target site's topic. Use anchor text with relevant keywords relevant to target site/target page. example: your site 1 is about cars your site 2 is about bicycles but has a page comparing cars vs bicycles on that page you make a link with anchor text containing "cars" + 1-3 other relevant words pointing to your site 1 like a logical part of a phrase or your content - including the keyword "cars". since you own BOTH sites, best practice would be to have such links fully integrated into the content text rather than outside the content text block!
