WordPress is well-designed for SEO from the ground up, but you can improve it significantly. Whether it's by using appropriate permalinks, proper image captions, or even cleverly linking to your own and other sites. The basis of good SEO is of course quality content, which will sell itself to a certain extent, but you can still help a little.
A great WordPress SEO helper is then some specialized SEO plugin for WordPress. There are plenty of these on the market, including well-known stalwarts like WordPress SEO by Yoast or All In One SEO Pack. Alongside these, you can find other plugins specialising in WordPress SEO for videos, Google XML sitemaps, broken link checks and similar plugins.
