The tables in the WordPress database, what are they? What is each one for?

I always like to remember in the courses I teach that Web 2.0 exists thanks to the databases if there were no tables within databases to store the dynamic information that we upload or write directly to the Web would not exist, we would simply have read-only websites.

WordPress of course, also uses databases to store the necessary information to make it work. As soon as WordPress is installed, a series of default tables is created in the database which is good to know what each one is for, so let's see them in detail.

So these are and for this they serve, watch them and take care of them. If you want to see a graph of all the tables and their relationships, you have it right here …

WordPress and color blindness

An article written by Antonio Villegas, from the company A / B Testing that talks about the color blindness and WordPress .

In addition to describing what color blindness is, has called me a lot. offer a series of tools to check if you're colorblind, highlights the fact of how friendly WordPress is with people who have this difficulty to distinguish colors.

Specifically, Antonio points out that – also in this – interface of administration of WordPress offers a design of high quality, with colors of high contrast that do not mix the meaning of the elements of color something vital for the colorblind ones.

It does not pass the same with some plugins, and sets the example Yoast's WordPress SEO although it also offers some trick to fix it.

Accelerate WordPress with these tips

 optimize wordpress speed

Nowadays, the loading speed of a site is very important, so much that it is part of SEO. Because your website goes fast or Google or any other search engine, you can be penalized for it.

So I'll give you some good tips to put the turbo to your WordPress and accelerate it as much as you can.

With these I've seen WordPress tips that have increased speed by 30, 50, 200 or more percent.

But this depends on how you do it, hosting and other things that I'll tell you now. [19659004] I give you 5 minutes to make you a coffee.


Let's go to the mess.

The first thing is to see the speed of your WordPress and see what's wrong or get stuck. [19659004] For the record, it's not just for WordPress and you can apply it to any other type.

We can use Google Analytics Pagespeed and other tools.

But like every master has his book, I'll show you mine.

The tool I use is called G metrix and you can register (it's free) or not if you do not want to.

The advantage of registering is that you keep the urls and see the advances.

 GTmetrix "width =" 550 " height = "315" srcset = " 550w, -500x286.png 500w "sizes =" (max-width: 550px) 100vw, 550px "/> </p>
<p> If we put a url of either the main page or another of the pages, we can see the performance of the web both in <em> Pagespeed </em> as in <em> Ylow </em>but in a deeper way we will see where our web fails. </p>
<p> The greener a better section is. But you must take into account that there are things that can not be improved, since it does not depend on our website. </p>
<p> As for example links to social networks, the comment system <em> Disqus </em> and any other external service </p>
<p> In my case I am more aware of <strong> Pagespeed </strong> for errors and the <strong> Timeline </strong>since in the latter you can see if there is a file or url that is slow to load and slow down your site </p>
<p> An example of a website of mine, which I will certainly put on a diet right now that I see something heavy. </p>
<p> <img class=

For the record of 95 % of my website is after having chosen a good template and have done a good job to get this result.

Some of those problems are the ones that make web heavy and those tips I'll talk to you in this guide.

I will try to review the most problematic and what and or solution.

Before doing anything, I want you to write down the data that it puts you on the top right:

  • Page load time: The time it takes your web to load.
  • Total page size: What your website occupies.
  • Total number of requests: The number of requests made to the server.

Each time you carry out any of the tips, you'll see how your WordPress is taking the turbo and low in everything.

Specifies a cache validator

The cache is a system that saves a copy in the browser of certain static files such as images, CSS and others.

The advantages of this is if you usually enter a page from time to time, only new content will be loaded and you will not have to download images and more.

It saves time and effort to the server and you as a navigator, saves data and of course load time.

If you do not have it active, copy and paste the following in your arc hivo .htaccess .

Activate gzip compression

You may have marked that error if you do not have activated compression on your website.

That may be because your hosting does not activate it to your clients . If so, I would personally leave that hosting as soon as possible.

It is very important, since it reduces the size of files that can be compressed such as text, HTML, CSS, etc.

This saves a lot of traffic and the web loads much faster.

Ask your hosting to see what they say.

Activate Keep-Alive

This is a system that improves connections and this one almost certainly has your hosting activated, but we must also activate it in the .htaccess .

This improves the loading of the pages since it modifies the information of the headers, according to the client that receives the file.

The same, to .htaccess .

Deactivate ETAG

] The etags have to do with the versions of the files and usually tend to slow down the load and I think it is by checking them.

The solution is to remove them and problem solved.

Copy the following to .htaccess .

Remove the static resource request chains

This one I love.

It turns out that WordPress has a system of versions of files like JQuery and others.

Maybe the web has some scripts or CSS files that have version control of type file. css? ver = 3.2.4 .

This helps keep track of the file version, but apart from that anyone can see if the version of your script has a known bug, it also helps the web go slow

To remove this we have 2 options, but with the same code

Paste it into our file functions.php :
