Correlation SEO In On-Page Optimization -- SEOKINGTOOLS.COM
Now that you know what Surfer can do, you’re most probably thinking, “How does Surfer know which ranking factors are the most crucial for SEO?”
Unfortunately, Google and other search engines aren’t transparent about their algorithm. Enter correlational SEO.
Correlation SEO analyzes various ranking factors in order to determine which ones have the biggest impact on ranking. Surfer’s data comes from reverse engineering the search engine results page (SERP)—it looks at what top-performing pages are doing that you aren’t.
Instead of giving you vague advice (“long content is better than short content”) or ballpark figures (“aim for 1,000-2,000 words per article), Surfer provides recommendations that are based on pages that already rank for your target keywords.
And this extends to more than just word count. Surfer also looks at what kinds of pages rank best (e.g. long-form vs. quick answers), what kind of media they contain (e.g. graphics, lists, etc.), what topics they cover, and what words and phrases are most commonly used.
Surfer wasn’t the first correlational SEO tool to hit the market. Cora and Page Optimizer Pro came earlier and are both exceptional tools as well.
One of the major criticisms of correlation SEO is that correlation doesn’t mean causation—just because a competitor is ranking while using certain practices, it doesn’t mean that those practices are the reason they’re ranking.
But by optimizing your content so that it’s similar (but higher-quality) than the content that Google ranks at the top, you are more likely to take the top spot.
The trick is to know which pages to compare yourself to, so that you aren’t introducing the wrong kind of change.
