As of my most recent modification in September 2021, Web 2.0 sites are platforms that enable users to create and share content, generally in the form of articles, blog posts, or other forms of media. These strategies can be used to generate backlinks, but keep in mind that the SEO landscape evolves over time, and the effectiveness of specific techniques may vary.

When creating backlinks on Web 2.0 sites, keep the following factors in mind:

Platform relevance: Choose platforms that are relevant to your industry. Backlinks from relevant sites carry more weight in terms of SEO.

High-quality content: Write high-quality articles that offer important information. Google favours content that is valuable to users.

Avoid keyword stuffing and over-optimization using natural interlinking. Your links should be consistent with the rest of your content.

Diversification is not relying solely on Web 2.0 sites for backlinks. It is preferable to have a diverse backlink profile from many sources.

Look for platforms that are routinely updated and have a large community presence.

Consider the Web 2.0 platform's validity and authority. More authoritative platforms are more valued.

The following Web 2.0 sites were popular for building hyperlinks with articles as of 2021:

WordPress.com: is a well-known blogging platform. You can start a free blog and write backlink-rich articles.

Blogger: Google's Blogger is another popular platform for creating blogs and articles.

Medium: is a platform for publishing articles and stories. It has gained popularity as a venue for long-form content sharing.

Tumblr: Tumblr allows you to create blogs and share a variety of content, including articles.

Weebly: is a website builder that allows you to create blogs and webpages that include articles and hyperlinks.

Wix: is a website builder that, like Weebly, can be used to produce content and backlinks.

While Web 2.0 sites can be part of your backlink strategy, a well-rounded approach that includes a mix of other quality backlinks (guest posts, niche directories, industry websites) is recommended for a balanced and productive SEO strategy. Furthermore, because the SEO landscape is continuously evolving, maintaining current on the latest best practises and recommendations is always a good idea.
