Seo main factors
Search engine crawlers are able to follow the links of your website exclusively if they use proper <a> tags with resolvable URLs:
If a link is an <a> tag with an href attribute, crawlers will be able to follow it correctly; on the other hand, if the format is different (i.e. without an href tag or other tags relative to a link), crawlers will not follow it: this is due to the script events.For instance, crawlers can follow:
<a href="https://example.com"> <a href="/relative/path/file"> They can not follow: <a routerLink="some/path"> <span href="https://example.com"> <a onclick="goto('https://example.com')">
You have to be sure that in the <a> tag you are linking to a valid URL, namely that the crawlers can interact with it, such as:
https://example.com/stuff /products /products.php?id=123
What is not considered a valid URL:
javascript:goTo('products') javascript:window.location.href='/products' #
