As for me, I don't do link exchange that much. I've read somewhere that link exchange is quite risky nowadays, especially if the linking partner site is not relevant or not within the same niche as your site's. What I believe that's really effective for an
SEO campaign is 60% relevant quality backlinks, 20% non-relevant High
PR pages backlinks and 20% on page optimization including xml sitemap. and for link building strategies, I would really go for article submissions and microblogging that have quality content on it plus your keyword being an anchor text or included within the title

that really works fast, since google indexes them faster than other link building methods
