01) Page Loading Time
WordPress is still a slow platform because of the numerous plugins, overburdened databases, and codebases.
However, those aren't the only factors that can cause your site to load slowly. Large graphics, a lot of text on a page, and unstable hosting can all affect the speed of your website.
Without a doubt, WordPress's biggest flaw is its lack of security. WordPress is an open-source platform that mainly relies on plugins and themes to customize it. Because no one is monitoring the plugins and themes, they can easily contain bugs or harmful code lines. Furthermore, as previously said, WordPress is the most widely used content management system in the world today. Because of this, WordPress has become a popular target for hackers worldwide. WordPress is, in fact, the most hacked CMS platform worldwide, according to Sucuri research.
03) Updates are required frequently.
Simply installing WordPress will significantly assist you, as this platform requires a theme and at least a few plugins to function effectively. After a WordPress update, parts of your theme or some plugins may become unusable. The more plugins you install, the more likely you will run into compatibility issues. The entire WordPress maintenance process can be complicated, and you must be willing to make changes to your plugins and theme to have a functional website. If you don't have the budget or the knowledge (design, programming), and WordPress doesn't offer help in general.
04) Coding is required for customization.
HTML, CSS, and PHP knowledge are required to make specific changes to your WordPress site. If you want to customize it uniquely or improve the design, you may write many sophisticated code lines. Things can go well if you're in the category of individuals who know, but if you try to write code without having the right skills — which is the case for the vast majority of people in this category — you can cause a lot of damage to your website.
05) Poor SEO Ranking
WordPress is an SEO-friendly platform without a doubt. But WordPress also can cause plenty of issues for those with little to no SEO experience and knowledge. The most well-known is perhaps the one generated by the WordPress category and tagging system. Google will label the content as duplicate content if it is over-tagged or marked into many categories, which will impact your SEO rankings.
06) It might be costly.
While WordPress is free in and of itself, there are substantial fees when considering the complete picture. WordPress relies on plugins and themes for customization, and while some are free, they are not always dependable or secure. Furthermore, you must purchase a theme if you want your website to stand out and provide a positive experience for your visitors, as free themes are overused. Finally, it can be costly to maintain your website up to date, especially with so many upgrades coming out all the time.
