WP-Optimize helps you to:

Make space: When you edit a post or page on your website, WordPress automatically saves the new revision to the database. If you edit things a few times (and particularly if the post is long), your database soon gets clogged up with old revisions that just sit there, taking up valuable space. WP-Optimize removes these unnecessary post revisions, freeing up valuable Megabytes of data and increasing speed and efficiency. It also cleans up your comments table, removing all the spam and un-approved comments that have built up with a single click.

Take control: WP-Optimize reports on exactly which of your database tables have overhead and wasted space, giving you the insight, control and power to keep your website neat, fast and efficient.

Keep it clean: Once enabled, WP-Optimize can run an automatic clean-up on a schedule, keeping a selected number of weeks' data, according to your specification.

When you use this plugin for the first time or just updated to major version, make a backup of your database (i recommend UpdraftPlus). Though none of the queries used are dangerous, it is always the best practice to make a database backup before altering your database.

1. Create unique Title Tags and meta tags for all pages and posts. (Try with All in one seo plugin or Yoast)

2. Create proper url structure for ex default url structure will be (example.com/?p=38), you can change to (http://example.com/wordpress-seo/). For changing the URL Go to Settings >> Permalinks

3. Fix the canonical issues i.e) use any one version of WWW or Non-WWW your website url. You can redirect by editing the .htaccess

# Begin 301
RewriteEngine On

RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

For optimization of Wordpress websites. There are two popular and easy plugins available for it. The one has name "All in One SEO Pack" and other's name is "Yoast". Both are widely used in the optimization of Wordpress website. According to my experience, "All in One SEO Pack" is best. You can use both and experience yourself that with which one do you feel comfortable.

Hello dear Webmaster. I want to share your experiences and mistakes when working with the plugin all in one seo pack. Very useful plugin for any webmaster, but the benefits it will bring when properly configured. I watched video tutorials on setting up this plugin, learned how to set it up for a couple of minutes. I decided to create a store on WordPress and installed the plugin all in one seo pack, everything is fine, created the site map, but store – it's many pages, how to register for each product meta name description? Very difficult to put it mildly. And the plugin all in one seo pack is a great opportunity auto fill description and keywords, well, I think the solution to the problem. It's all lazy, quickly, fast to create. Put a tick auto-fill the description and downloaded the goods. In the search after two updates, there were only a few pages. Not the result expected. This "experiment" I conducted on the shop kladproraba.com sad was the study of this miracle button to automatically fill in the fields description. You learn from mistakes. Will have to fix it, since the traffic is mainly expected to come from search engines. Spent a bunch of time wasted, one consolation – the store is not under the filter. Now, no automation, all manual, and what You suggest. Plugin all in one seo pack installed necessarily, but a tick on the automatic filling of description not set. Fill these fields yourself-handles. I hope my information will save You a lot of time and nerves, good luck and success!

I'd start with making sure it is grammatically correct before ever worrying about SEO. You can rank #1 for your targeted phrase but if the English on the page is poorly written, you might as well be in spot #100; nobody is going to trust the site.

I only mention this because of the grammar in the OP's question. If the site is written like that, you have far bigger problems than SEO.
