Would've been easier to Google this. In a nutshell: <a href="h ttp://somesite.com" rel="nofollow">Some link</a> - Google and other legit search engines won't crawl this link (this link won't have any impact on the page ranking). To make a link dofollow simply avoid using rel="nofollow".
Do-follow" and "No-follow" are attributes used in HTML coding to give instructions to search engines about how to crawl and index the links on a webpage. Do-follow links: These are regular links that allow search engine bots (like Googlebot) to follow them and crawl the linked pages. They pass on "link juice" or "page rank", which is a measure of a page's importance in search engine algorithms. This can positively impact the SEO (Search Engine Optimization) of the linked page. No-follow links: These links have an additional HTML attribute "rel=nofollow" which tells search engine bots not to follow the linked page and not to pass any "link juice" or "page rank" to it. They are often used for external links, sponsored links, advertisements, and comments on blogs to prevent manipulation of search engine rankings.
Do-follow and no-follow links are two types of hyperlinks used in website content, each with distinct attributes and implications for search engine optimization (SEO) and link authority. Here's a professional explanation of both: Do-follow Links: Do-follow links are hyperlinks that allow search engines to follow them and pass link equity or "link juice" from one webpage to another. These links are considered endorsements from one website to another, signaling to search engines that the linked-to webpage is trusted and authoritative. Do-follow links are typically used for editorial purposes, such as citations, references, or recommendations within content. They contribute to the linked webpage's search engine rankings and organic visibility, making them valuable for SEO efforts. No-follow Links: No-follow links are hyperlinks that contain a rel="nofollow" attribute, instructing search engines not to follow them or pass link authority to the linked webpage. These links are often used to prevent the endorsement of questionable or untrusted content, user-generated content (e.g., comments, forums), or paid links. No-follow links were introduced to combat spammy link building practices and manipulate search engine rankings. While they do not directly contribute to a webpage's search engine rankings, no-follow links can still drive traffic and provide value in terms of referral traffic and brand visibility. In summary, do-follow links facilitate the flow of link authority between webpages and contribute to SEO efforts, whereas no-follow links signal to search engines not to follow them and are typically used for non-editorial purposes or to mitigate SEO risks. A balanced link profile consisting of both types of links can help improve a website's overall search engine visibility and credibility.
Do-follow links: These are like strong recommendations. They pass on "link juice" to the linked website, which can help it rank higher in search results. Getting do-follow links from high-quality websites is great for SEO! No-follow links: Think of these as friendly mentions. They don't directly boost SEO ranking, but they can still drive traffic to your site and show visitors you're connected to other relevant sources. They're still valuable!
