Excellent news that you were able to get it to work.

I'd say yes your social media links have zeroed out because they used the old URL without the www. It's not a Google thing though and won't be fixed by re-indexing the site. However, my understanding is that Wordpress 301 redirects the links from the non-www URL to the www URL so your link juice should still flow to the new URLs and the shared links will still resolve to the right page. The only caveat is that the actual number for likes and shares in your social share buttons has reset to 0.

In my opinion, it's a good move (you're just missing the "eye-candy" for now) and this number will rise again as people begin to share using the new URLs.

Edit: just saw you have already checked with FileZilla. I've created a new htaccess file and pasted in what Wordpress provides as an example then uploaded the new htaccess file to fix this on other sites.

Hi Scott, yes, this should be correct. After updating this value, you may need to log back in to continue using the admin area. This is because you are likely logged in at the old sub-domain of simply onestopmuscle.co.uk rather than the new sub-domain of www.onestopmuscle.co.uk and with the new redirect, you have to log in again. It's kind of strange behavior I know :).

In the Wordpress admin area, under General Settings, there is a input for WordPress Address (URL). Here, you can set the URL you would like to use for your base URL (e.g. http://www.example.com/). If you use www. here, your pages should use the www. version.

Hope this helps!

It's pretty easy to create a favicon.ico file. Favicons can be many sizes from 16x16 to 64x64 and, since you just want to get rid of your 404 results, I suggest going with 16x16 to start. This website is great for creating one without much work. Otherwise, you can use any image editor to create a small image and then rename it to "favicon.ico". Whichever method you use, I suggest creating a favicon that looks like your logo much like SEOmoz has done with theirs. Once you've created your favicon, upload it to your server.

Edit: I should also note you can remove the reference to the favicon.ico file altogether. To do this you would remove the following HTML from your webpages that are producing your 404 errors:

<link rel="<a class="attribute-value">shortcut icon</a>" href="favicon.ico" />

Your second 404 looks to be from a missing script that is often used to present Flash content. This file is also generated when you use Dreamweaver to create a webpage that includes Flash. You can either remove the call to that script from the HTML or look for a copy of the file online and upload it to your server.

To answer your main question, content aggregation is not good SEO.

First, search engines are going to see scraped duplicate content. Second, if you add any ads at all, you will only increase the odds you will be viewed as a profit-seeking-curated-content farmer which may as well be equivalent to spam.

Panda and Penguin were released to deal with sites that provide no-value content aggregation.

If you aren't adding value, don't do it.

OK, all that being said, I do find Flavors.me interesting.

I think it might work as a personal website used to drive traffic through to other channels. Like About.me, but with a bit more oomph!

Provide a solid profile (unique content providing value) that points to the places I spend my time on the Web.
