I don’t know what xfish is, but there are several ways to include meta tag information, though few search engines actually “use” the information any more since it has been abused. In developing my WordPress site, I haven’t put my meta tags back in and my page ranking has actually gone UP – I knew they weren’t being used much, but I didn’t believe it. Now I do.
Of all the meta tags you can use, keywords are the ones that are still of some value. There are several plugins you can use to put keywords in your site, so check https://www.wp-plugins.net to find one that suits your needs. I personally like Jerome’s keywords plugin but you can choose your own.
Now, a word of warning. If these plugins are deactivated for any reason, and the tag that calls out the info in the header for the keywords is still there, your site may choke and you will get a line error. They work great, but only when activated, so this is a minor nusiance.
Okay, as for the rest, there is also a very easy solution, if it is important to you to have this information in your header. Open the header.php
template file in the Theme you are using. In the normal place where you would have this meta information, type it in.
Instead of the information being specific to your individual web page content, make it specific to your site. So if your site is about growing flowers, make the description tag read something that groups all the information together like:
<meta name="description" content="The art of growing flowers website covers a wide range of plant and flower growing techniques including weed management, fertilizers, pruning, planting, as well as growing seasonal and annual flowers, flowering herbs, and wildflowers." />
You can even put in keywords without using a plugin setting the keywords list to reflect the content of the site in general.
