SEO is the only way to rank your website high on search engines, and drive organic traffic, generate revenue and sales. Sometimes despite doing SEO, your site might not be ranked high. That’s because you have overlooked certain issues. One major issue is duplicate content. If your website has a lot of content that also appears somewhere else, it will harm your SEO performance. Slow loading speed and your web pages not crawling on search engines are some other common SEO issues that need immediate attention for better performance.
