SEO Tune Up
– One of my favorite SEO analysis tools is this single page SEO Analyzer
from SEOWorkers. The in-depth results includes an HTTP headers check, meta tags analysis, keywords relevance, URLs found in the page, keywords found in the anchor text, keywords in the 'alt' attribute of images, and heading & phrase elements. The analysis also includes helpful articles to explain the results as well as videos from Google to clarify best practices on alt attributes, titles and Google's use of meta descriptions.
