1. Yoast SEO :- It’s one of the most wholistic WordPress plugins for SEO, with features that ensure optimal success for your site when it comes to SEO.

2. All in One SEO Pack :- its features are similar with Yoast, All in One SEO Pack claims to be the only plugin that integrates with WordPress E-commerce sites. Also, one of its unique features are automatically generating meta tags and optimizing titles for better search ranking.
3. SEO Ultimate :- SEO Ultimate has the basic SEO features covered but adds unique ones that are designed to keep SEO practices at the forefront of content creation. In addition to title tags and meta description editors, it has a long list of deep linking functions that includes putting a link in a draft that activates when it’s published.
Another user-centric feature is the Author Highlighter, which includes an author’s Google+ profile in search results.
4. SEO by SQUIRRLY :- Squirrly’s only useful in Pro version, so we’ll talk about that. It also calls itself “a plugin for non-SEO experts” which is very apt.
