MetaTags
The MetaTags page looks very similar to that of the previous iJoomla MetaTag component, which was the predecessor of iJoomla SEO. MetaTags is a lazy web dev's metadata dream because you can automatically create meta title, keywords, and descriptions from your content, or even from other meta tags. It's always better to tweak these by hand, which you can also do here, but conveniently all in one page. This section is a tremendous time saver.
Redirects
Redirects lets you enter a link title or image, and a corresponding url, then gives you a code snippet like . You can then use this snippet in Joomla! content articles, or anywhere plugins are executed. This is a timesaver if there's a particular link you're always creating and you'd rather just paste this snippet, which can then be edited in one location if you ever want to change the text, link, or image. I like timesavers; the only thing that scares me is what happens if you choose to stop using iJoomla SEO one day? You'd have to update all these snippets. This is one of the only features that will cause (immediate) pain if you stop using the extension one day.
Internal Links
Internal Links is a super cool and powerful feature. You can create a keyword such as "projectfork". Any time this keyword occurs in content, it will now automatically link to any internal menu item, article, or an external link. This is great for internal seo, but also very promising for a link exchange deal where certain keywords link to partner sites and vice versa.

Keywords
My absolute favorite feature is Keywords. For all your keywords, you get the Google ranking (which can be checked manually), position change, link to Google page, and the number of times the keyword occurs. These stats work for Joomla! article, menus, Moset Tree, Sobi, iJoomla Magazine, Digistore, Newsportal, and K2, which is really cool. You can also make your favorite keywords sticky, to keep a closer eye on those.
From iJoomla: "a similar service would cost $50-250/month and the number of keywords would be limited". By these numbers, iJoomla SEO would pay for itself in 1-2 months.
This is the deciding factor for us to install iJoomla SEO on JoomlaPraise.com.

Pages
The Pages manager is an alternate way to view all your articles, but with a strong emphasis on SEO. You get a rolled up view of all your articles (with filters) where you can quickly see Outgoing links, Keywords/Phrases, and the number of keyword occurrences in these articles. You can quickly edit any article with a squeezebox view that also include that article's metadata. The squeezebox editor is a great idea and well executed.

Bottom Line
$100 is a lot for some people to spend on a Joomla! component to some, but that all depends on your perspective. Many companies using Joomla! are spending hundreds or thousands per month on Google Adwords alone, and countless hours (or dollars) tweaking content themselves. iJoomla SEO can certainly cut down the time invested in SEO (specifically metadata), automate several tedious SEO tasks, and present SEO solutions that many aren't aware of. Plus if you're paying for keyword tracking, this fee is nominal in comparison.
iJoomla SEO's strength lies in metadata. Some Joomla! devs have questioned the significance of this, as Google doesn't use meta keywords . This is true, but Google does use all the other meta info, which iJoomla SEO makes very easy to manage.
I've spent a couple of weeks with iJoomla SEO and would really need a couple of months to see the true SEO benefits, but my first impressions are great. I can say without reservation - there's no other Joomla! extension like iJoomla SEO out there. I'm installing it on our live site and putting it through some real-world tests. I'll post an update on the outcome.
