I am still in the process of updating the new Wordpress Theme. I have noticed a few things that I forgot to change while making the switch.
Tracking code
If you have any tracking code on your site from services like Google Analytics or Site Meter, remember to add it to your new theme. I manually place my tracking code into the footer.php page, so when I made the switch to this new theme, the tracking code was no longer there. Unfortunately, that means I didn’t get statistics for RevenueQuest for about three days.
Advertisements
Another thing I looked over, this time for only a day or so, was advertisements. Remember that when you change to a new theme, unless it is one of those made-for-Adsense themes, it won’t by default have advertisements on the pages.
Luckily, this new theme I am using has widgets for the sidebar. So now if I ever switch to another theme that is widget ready, I won’t have to worry about adding advertisements to the sidebar.
Plugins and such
Some plugins allow you to manually add code to different pages. For instance, you can add code to each post to display posts that are related. You can see on this blog that each post is given a popularity value. I used to display the most popular posts at the bottom of the main page, but I haven’t added that feature to the new theme yet.
Make sure you take a thorough look through the pages on your blog to see if it is missing any of these things when you make a theme switch.
