In theory, WordPress is just another way of putting your website online. So, in theory, SEO for WordPress should be subject to the same rules that apply elsewhere. And, to an extent, that's true. But there are some subtle (and not so subt) differences that you need to be aware of to make sure that your WordPress site is as well optimized for the search engines as it can be.
WordPress itself has the ability to be extended with "plugins" that hook into the heart of WordPress and allow you to do almost anything with it.
If you have not already done so, you should install an SEO plugin.
There are a variety of these available but the market leader currently is the one from Yoast, simply called WordPress SEO. It's well supported and regularly updated, which are both very good signs especially for something that you're going to be trusting your online success to.
The order of these boxes will vary according to your chosen plugin but they will include:
- Your target keyword phrase. This is optional but it allows the plugin to show you how well your page is optimized for that particular keyword phrase so I'd recommend that you complete the relevant box. It also has the advantage that if you go back to the page in a few weeks or months, you will not have to rely on your memory about what you were targeting!
- Your page title. Different WordPress themes handle titles in a variety of ways and do not always show the best possible page title to the search engines. An SEO plugin takes back this control so that you're not stuck with the default option given by your chosen theme.
- Meta description: this is again supported by different themes in different ways. It's easy to ignore as it does not actually show on the page on your site. But it does influence how your page shows up in the Google results as well as the default text that is put into the relevant boxes when your page is shared on sites like Twitter and Facebook.
There will also be other options – maybe hidden in an "advanced" section – that will tell you other things and allow you to easily fine tune the way that your WordPress posts and pages show up.
It's worth exploring those other options, even if they seem daunting at first. There are plenty of tutorials around that will help to explain anything that does not initially make sense. But because most people do not delve that far into things, it's usually safe to leave these at their default settings.
As far as plugins go, that's probably all you need to do.
The other things that need to happen are the same for WordPress as they are for any other website: making sure that your page content is good quality, that you update your site regularly, etc.
