If you make it your business to understand how well Web pages are optimized for search engines, proSEO is a good way to go for iPhone users. This handy app from Infinidigm enables to look at a Web page's keywords, tags, HTML and other important attributes that factor into a site's search engine ranking.
Enter the URL of the Web page you wish to analyze into the app's browser and bookmark it if you plan to revisit it. After the Web page loads, tap the Analyze button and proSEO does the heavy lifting.
You can analyze a page by selecting one of four options: Source Analysis, Body Text Analysis, Anchors and Link Text and Images and Alt Text. Tap, say, Body Text Analysis and you'll see the all the text that appear on your chosen Web page, the page's word count and its stop word ratio.
Some of that is evident, even for users who are unfamiliar with SEO jargon. Stop word ratio is a measure of the number of times words such as "the," "and" and other oft-used words appear on a page. Searchbots ignore commonly used words like those.
For example, a look at AppCraver's home page reveals 1979 words (which includes menus, captions and other text) with a word stop ratio of 43.507%. That means about half the words on the home page are indexed by searchbots.
Drill deeper into the Body Text Analysis by tapping the Phrases button and you'll get a list of words on the home page and how often each word appears. That alone won't tell you much. However, you also have the option to remove stop words and to use a slider to see which words appear in phrases.
So, for example, to see phrases of up to five words (the maximum), adjust the slider and up will come a list of phrases and the frequency in which they appear on the page. The phrase "apps in the App Store" appears four times on the home page. That's pretty good from AppCraver's point of view because that's one combination of words a person is likely to enter into Google or another search engine.
proSEO enables you to look at how well a page is optimized based on what are considered to be best practices. If you look at Alt tags — the text that describes an image's content — and see that the text is missing or does not closely match up to your the keywords you want on your site, you should fix that.
proSEO is not only useful for people who already know what SEO is all about but it's also a great learning tool for people who want to understand what goes on behind the scenes and see what sorts of stuff searchbots feed on.
There is a problem with proSEO, and it's one the developers readily acknowledge. That is, the app will bog down and even crash when your handheld is low on memory. Web pages with lots of content will do that. The app is also prone to slow to a crawl between page loads if connectivity is less than optimal. In other words, you'll be okay on a Wi-Fi connection; you'll be drumming your fingers over 3G; and you probably won't get anything done on EDGE.
If you need to look under the hood of Web pages, proSEO is worth its $9.99 price tag.
