I have a box filled with search engine optimization (SEO) tools. I use some. Some have ceased relevance; some I don’t remember why I bothered. The one tool I continually use is Poodle Predictor by GRI Technologies.
I’ve got two sets. One SEO-specific; one SEO/Web Standards.
Poodle Predictor is an excellent SEO/Web Standards tool with a funny name. The title — “Poodle Predictor - See your site like Google does. Simulate search engines and predict your Google listings” — is regular Phineas Taylor Barnum.
Further, it visually displays sites as plain text. After all, search engines are themselves simply reading HTML sans presentational markup, e.g., CSS position:absolute, which makes The Poodle Predictor an invaluable tool for the resolution of Accessibility and search engine optimization issues. It’s very effective when explaining deficiencies with the overzealous use of AJAX or Flash in standards-compliant sites, by showing clients a—Mostly—blank page.
So, Yes. One can predict Google listings as well as every other search engines’ listings.
And, on that odd occasion, it will perform site validation. [Note: I seldom perform HTML validation on sites that only want SEO performed.] After analysis, this one particular site was fixed: titles, description, various other things and extensive copywriting. We waited two months but little improvement occurred in search results. I don’t remember—it could have beem content-to-code ratio—my reason but I ran one of the fixed pages through Poodle Predictor and found the problem. An unclosed
<a href> attribute twenty lines above the editorial content which was rendering all of the editorial (text) content as one very long link text. Google could not find any content. That error was corrected and search results improved.
[Elementary aside: An SEO reason why sites should undergo validation.]
Poodle Predictor is one of those tools that has duality of purpose I recommend.
