Welcome to the Q&A Forum

If you merge the two sites say into atlantaeventscorporate.com and 301 all of atlantaeventweddings.com content to its new location at atlantaeventscorporate.com you will effectively be combining the page ranks and traffic scores of the two. Of course its not quite that simple and there are ways this could go wrong but I would look into that. Perhaps just turn wedding into a subdomain with a directory style url?

you would need to edit the single.php file.
look for:
<span < code="">class="post_date">`'j F,Y'); ?>`

change it to:
<span < code="">class="post_date date updated">`'j F,Y'); ?> then for author look for:</span <>``</span <>`

```<span < code="">class``=``"theauthor"``></span <>``or<span < code="">class``=``"theauthor"``></span <>``change to: <span < code="">class``=``"vcard author"``>
<span < code="">class``=``"fn"``>`

or
<span < code="">class="fn"``></span <></span <>`</span <>````` 
preferably you would copy the existing parent themes single.php file into a child theme and make the edit there

/e I should mention that it is common for theme creators to abstract out these functions into less comprehensible formats like this entry from the Avada theme:
| Personally either way I dont bother to fix these particular "errors". But that is mostly because authorship markup ranks nil in regard to what I am up to.

Your other option is to delete or comment out the existing related markup and write new or utilize one of many plugins that will address this particular issue.````

I'm tempted to say in order to optimize local search results I'd go with:

• www.website.com/city1/stop-smoking

• www.website.com/city1/weight-loss

etc..

Id probably go this route for a simple solve. I believe you would want to remove or disable the current handicapped markup.
