Our excellent WordPress SEO plugin costs you less than your web hosting. We are constantly developing it since release 2014 to make it the best SEO plugin in the world.

FAQ & support

We recommend the Block Editor (also known as Gutenberg Editor), which was introduced with WordPress 5.0. It is very easy to use and has a very search engine friendly source code structure. Our WordPress SEO Plugin also works with Elementor, Page Builder (formerly Visual Composer), Thrive Architect, Visual Columns and Advanced Custom Fields.

The best thing to do is to use an individual theme, which is developed exactly for your use. With Websei.de we also offer our own free WordPress SEO Theme, which is easy to customize and fast. But premium themes like Avada, Divi or Enfold also work. Important: The more extensive your theme and design, the more focus you should put on a PageSpeed optimization.

Quite normal :-) You can also use it to optimize categories, keywords and of course CPTs. It also offers you rules for indexing them in the metadata. A few tips on taxonomies: Define the appropriate keywords for them as well and add short introductions there. At the same time, reduce your categories, keywords, etc. to the minimum – we do not use keywords on our website and only have four categories in our blog.

We sell the licenses via digistore24. You will be redirected there by selecting a license and can pay by PayPal or credit card.

After purchase, you will receive the license key and will be redirected to the installation guide.

After one year the subscription will automatically be renewed. You can cancel it at any time.

You can still use our SEO plugin, but it will be reduced to the free version modules after the subscription has expired: metadata, sitemaps, statistics, and URLs. Your content optimization – SEO texts in the broader sense – will of course be preserved.

Yes, you will receive 25% commission on successful sales through your referral. You can register here.
