This is really bad, I found some of my site has been affected by this plugin wp mobile pack. Traffic drop from 2K unique visitors daily into 400 unique visitors daily. I try to diagnose the problem and finally found it (after a month *lol*). This drop cause by wordpress plugin called wp mobile pack. It’s actually nice plugin to convert our wordpress site become mobile friendly site with option to view desktop version or mobile version.

The big problem is this plugin will make your wordpress site become mobile friendly without change any meta including your page title. For example my meta description is article title+20 words article content+site/blog title. If we enabled this plugin it will created an duplicated meta and duplicated title, in the end it will caused big problem impact in SEO.

Solution: I try to using google webmaster tools called parameter handling. But I’m not sure if this things will affect better on next index date. Actually I was thinking about giving meta noindex and nofollow on mobile site themes but it’s looks like this mobile themes can’t modified since theme structure following desktop version. I also thinking giving rel canonical maybe can help us to fix this problem.

The result in today is better than yesterday I seen traffic growth 40%-60% from normal time. I will removed this plugin from my site if there is no working solution for this problem.


Beside this problem there is some important changes needed for wordpress user to tell google and other crawl robots to only index articles and pages. I believe tags, archive, and category not needed to get index since it will only spam google index. We can do this using robots.txt, example:

#General Bot
User-agent: *
Allow: /
Allow: /wp-content/uploads
Disallow: /cgi-bin
Disallow: /wp-admin
Disallow: /wp-includes
Disallow: /wp-content/plugins
Disallow: /wp-content/cache
Disallow: /wp-content/themes
Disallow: */trackback
Disallow: /trackback
Disallow: /comments
Disallow: /category
Disallow: /category/*/*
Disallow: /tag
Disallow: /author
Disallow: */comments

# Google Image
User-agent: Googlebot-Image
Allow: /*

# Google AdSense
User-agent: Mediapartners-Google*
Allow: /*

#Google Adwords
User-agent: Adsbot-Google
Allow: /

#Google Mobile
User-agent: Googlebot-Mobile
Allow: /



This robots.txt sample will not allowed all crawler robots to index tags, archive, category, etc. It will crawl and index some of we allowed. We won’t need all our tags to get indexed since it will only spam google index right?

If you’re using sitemap generator plugins make sure to set it only generate articles and pages to be included in your sitemap. Remove tags and other from generated sitemap. I believe this can be done very easy even if you’re using another sitemap generator.

After this small changes I see better result for today but not sure if it perform better in the future. You should stay away from wp mobile pack plugin if you’re care about your SEO. Keep watching and stay update with any changes.

That’s my share for today, Have a good day 🙂
