Do the Little Things in SEO Make a Big Difference?

Many companies and professionals in the SEO sphere often make “best practices” recommendations to clients that include items like:

* Switch from underscores to hyphens to separate words in the URLs
* Employ the H1 tag for page headlines
* Use H2s and H3s for subheadlines
* Use the keyword you’re targeting on the page in bold/strong at least once
* Change your internal links to contain the anchor text you’re targeting on the page
* Move the keywords to the front of the title tag
* Reduce the code to content ratio
* Apply relevant alt tags to images & photos
* Nofollow links to pages like login, register and legal disclosures
