Hi, Long time did not ask optimization problem, analyzing some of today ranked on top 10 websites found two sites very fast, by querying technical articles, discovered the site by the CDN technology, will lower the experts, whether this technique Ranking play an important role? Thanks
Sorry, but your question isn't understandable. Are you asking if using CDNs will affect search engine rankings negatively? If that is your question, then no, they shouldn't. Scott
The site speed is a major factor in the SERPs ranking, the website's caching, and an effective use of CDN play a big role in the ranking factors. Use them wisely!
