Basically Platinum SEO is a combination of the famous All in one SEO pack and Headspace2.   I think the author of  the platinum seo just modeled a lot of the code after these two plugins.  Even the set up looks similar under the setting section.

Is this bad?  Not entirely.   In fact, WordPress is mostly open to redesign and development by the community, that is that makes it so good, but people should give credit if credit is due.

This plugin is mostly the All-in-one SEO pack with ideas from headspace2.

Will headspace2 or All in one be bad if I use it?  No, they cover most of what you need for on-site factors, I like all-in-one over headspace2.

Platinum SEO pack is my new All-in-one for wordpress

For most of my sites, I am using the platinum SEO pack now as my main plug in on WordPress for on-site factors, even over all-in-one.  I personally modify my own templates so in reality most of the work for on-site factors is done but I use a few plugins anyway.

So if you want to keep your Search engine optimization simple for wordpress, try the WordPress Platinum SEO plugin.

Here is the truth. Headspace 2 is more complicated and powerful. However, it is marginally more powerful and greatly more complicated than the WordPress All-in-One-Seo plugin. So it is really a cost benefit choice.  For me the marginal benefit and great time I could spend getting up to speed on the wordpress headspace 2 plugin or working around some of the issues now, I could be exporing other ways to SEO my wordpress blogs.

Further at this juncture headspace 2 has some conflict problems with other plugins. All-in-one-SEO plugin not as many.

Further, WordPress is pretty good SEO ed out of the box. Only a few twicks are needed. More importance is the fundementals of SEO.

Therefore, All-in-One-SEO is better because of the ease of use. I am staying with this until I see a huge difference in those using Headspace 2 plugin for WordPress that can not be explained by link growth.
