Quite the opposite, wordpress compiles with all the latest web standards, so any blog created with WP may have a slight advantage over other sites using out of date language that has lots of errors.
I use Wordpress on all my websites I don't have any problem. Wordpress is very SEO friendly and, unless you don't spam, you shouldn't have any problems.
If your WP blog is hit, you need to check the following: 1: Your content: it may be unique at the time you written it but it may be published on many other sites/blogs after someone find it useful. This makes your content a duplicate one after syndicating it to many other blogs. Check in copyscape for the duplicate. 2: Back Links: You may have lost the Quality back links that you were getting previously. 3: The On-Page: Check that if you have done something wrong with your On-Page SEO. 4: Page Load Time: Check if your site load time is too high There is nothing like google hates WORDPRESS otherwise wordpress would not be so popular among the developers and users.
Mine is doing fine... nothing wrong with wordpress. You just need to prove to Google that your site isn't a auto blog and provide unique content and good content. I find that once a few links are "naturally" linking back to my posts I get a nice boost. Just don't go spamming your posts everywhere - use quality plugins to gain links in your own posts. I do this: 1. Update my old posts with a link to my new posts that are relevant - with a thumb and a text link. 2. Use a internal linking plugin - that turns relevant text into links to your own posts. 3. Try to monitor what Google crawls for your index page - the text used for index - this is normally your first text on left of the page. 4. Monitor hot trends and recent hot events and blog about them. 5. Use facebook comments, likes, twitter buttons etc. - visitors will share your unique quality posts - you don't need to worry about this. Google uses a pattern, it's strange but my Blog seems to have a pattern of similar four days worth of traffic, and then it climbs and sits the same for another four days and then repeats the cycle. Just stick at it and keep experimenting - sit on the configuration for a few days - Google hates a blog that is forever changing in design and SEO - it see's it as a work in progress and not a finished site.
there are 1000 of WordPress blogs/ sites. who are doing very well without any doubt.so i don't think Google really hate them
