WordPress is one of the most powerful and famous platform that it can be used for CMS. There are many thousands of WordPress plugins you can use for free, and also there are more that you can buy for different purposes.Some researchers showed that the previous year (2012) there were more than 21.000 free plug-ins in the WordPress plug-ins repository. Really huge collection.
Question: Should you use all of them? Answer: If you use all or some of them, maybe you fail.
You have probably seen a sidebar or footer of blog with a mile long list of awards and a multitude of links to other pages or custom widgets like social media, galleries etc. Some people go as far as including hundreds of flashy widgets. If you are thinking to use several plug-ins, you should first learn why using too many of them will impact negatively on your readership.
You don’t lose so much time to add a plug-in in your theme. Really easy to install enough to be available for your WordPress version.
In my personal opinion this is the only positive affect, but the the negative aspects are much more from positive. Below becomes the analysis.
1. Free WordPress Plug-ins may not be available forever
Now, the WordPress release version is 3.5. If you research for free WordPress Plugins, you can see that many of them they have not been upgraded for 2 years.
Scenario: Imagine that you build your own theme and you use some free plug-ins. After some time for 1 or 2 years, these plug-ins not been upgraded by the developers. What are you doing? First, you can become a victim of hacker attack. The second thing is that you find another plug-in which is available for the WordPress version.
Briefly : Victim of hacker attack and waste of time.
2. They may ‘slow down’ your Website.
This slow down occurs because every plugin you use sends a server request when each of your readers loads the site. The more plug-ins you use the most slow down the website.
Scenario: Imagine the effect of having 10-20 plug-ins when 10 users are on your site. What about more plugins with a thousand users? Really, do you want your site to be that slow? If you want, you fail.
3. Some of WordPress plugins are not secure.
If a plug-in that you use works well, doesn’t mean that it is absolutely secure. In the past there are a lot of cases for many free plug-ins that users have been asked to update their passwords after it was realized they were not secure.
Briefly : The resource of plug-in must me secure and know.
4. Conflicts amongst different plug-ins.
As was mentioned above, if you use so many plug-ins it is inevitable not to become a conflict between them. Also, this can been happen between the functions that you write and plug-ins that you use. Therefore, it is often useful to make backup for your structure of code.
Briefly : Confusion with functions and Waste of time.
5. You don’t learn how to code.
This is the most important of all. If you use free of premium plug-ins you will not ever learn how to write code.
Scenario: Imagine the effect that you want to create a widget for Flickr. Why are you doing that with a plugin rather than code; In the first case you spent a little time to find and customize instead of the second case that you would spend more time to create, but you will learn. The more code you write, the most control you have.
