Here is a list of SEO best practices that every SEO agency will be aiming for on the year 2018

• Instead of keyword stuffing, focus will be on strategic placement of keywords. Add keywords in image alt text, titles, H1 and H2 headings and permalink. Deep content, that is, articles with 1500 or more words will be preferred by SERPS.
• Linking – Guests posts, inbound links from reputed sites, good research and less spam will be seen favorably.
• User Experience- Websites optimized for smartphones, easy user interface, bulleted lists instead of lengthy paragraphs in content will all rank well this year.
• Practical- Websites having less than 2 seconds of upload time and a user responsive, easily navigated interface will score more.
• Keywords – Low density long tail to medium tail keywords will be preferred by search engines.
