Recently I've noticed that google searches will only turn up links to my blog index page. This means that a visitor who searches for a certain keyword will get a result that leads him or her to a page that displays my ten most recent posts, instead of taking them to the specific, isolated blog post.
I am wondering if this is a configuration feature within word press, or if there is some server-side functionality that needs to be in place.
In some cases, I can do a google search that DOES turn up a link to an individual blog post, but the link looks like an error with the heading "WordPress > Error" and a description that begins, "Error establishing a database connection. This either means that the username and password information in your wp-config.php file is incorrect or we can't ..."
Clicking on this link takes the user to a valid page, but no user in their right mind would click on a link that said "WordPress > Error."
I am concerned that this problem with how search engines pull data and display results for my site is affecting overall traffic to my site. Does anyone have any thoughts on this issue? Is this a problem on Google's end?
For an example of this problem, google "jean-isidore isou jj murphy" and view the top two links. One takes you to the index page, with unrelated material on top because it is more recent, the other takes you to the correct page, but through a link that looks like it shouldn't work.
Thank you for any advice you can give.
