Is it legal to link or embed somebody else&#39;s content if I give credit?
<p>I want to embed <a href="https://ruwix.com/widget/notation/" rel="nofollow noreferrer">this website</a> as part of a website. If the website is commercial am I allowed to do this if I credit them?</p>

<p>If not, is it legal just to link to them as part of tutorial page?</p>

<p>You should assume everything on the web - text, images, designs and code - is copyrighted, because (mostly) it is by default under <a href="https://en.wikipedia.org/wiki/Universal_Copyright_Convention" rel="nofollow noreferrer">Universal Copyright Convention - Wikipedia.</a></p>

<p>And most sites have terms and conditions of your use of the site that you agree to by accessing the site; it's a good idea to look for a "Terms of Service" (TOS) or other such document when you have questions about the content or use of any website.</p>

<p>Read <a href="https://ruwix.com/terms-and-conditions-privacy-policy/" rel="nofollow noreferrer">Terms and Conditions/Privacy Policy - Ruwix</a> linked at the bottom of each page:</p>

<blockquote>
  <p>The Ruwix Plugins on this website are copyrighted and can be embedded
  in other websites only using the iframe codes provided by us.</p>
</blockquote>

<p>The Ruwix site terms say you can embed their widgets only by using their iFrames, which means they retain control of the display on your site and control how their copyright notice appears and how their website is linked.</p>

<p>The site's terms <em>do not say you can embed the entire site</em> by iFrame. They do say that</p>

<blockquote>
  <p>Unauthorized use of this website may give rise to a claim for damages
  and/or be a criminal offence.</p>
</blockquote>

<p>And Rumix can choose to change the terms to reflect that embedding the entire site by iFrame is an unauthorized use.</p>

<p>The legality of embedding an entire site is complicated: see <a href="https://en.wikipedia.org/wiki/Copyright_aspects_of_hyperlinking_and_framing#Framing" rel="nofollow noreferrer">Copyright aspects of hyperlinking and framing - Wikipedia</a>.</p>

<p>Re: your second question: plain text hyperlinking (or even linking via image, ad, inline text, etc.) from one site to other pages and sites is not a copyright violation (see link above); if it was, the entire <a href="https://en.wikipedia.org/wiki/Hypertext" rel="nofollow noreferrer">Hypertext</a> design of the internet would be called into question.</p>
