When creating your blog, you want to check if it works in different browsers. For these purposes, you can use the free extension of FireFox – User Agent Switcher. After installing this extension is added to the browser menus and toolbars. User Agent Switcher installed as add-ons for FireFox, Flock and Seamonkey, and can run on any platform supported by these browsers – Windows, Mac OS X and Linux. PS Unfortunately, my FireFox version 3.0.1 plug-in refused to work. Reported that required version below. Also, when promoting your blog in search engines, it is necessary that the content of your blog was very readable, not only for people but also for search engines. Google advises to check what they see on the search engines your site, view it using a text browser such as Lynx. With it you can see a text version of page (no tables, JavScript, cookies, session IDs, Frema, DHTML and Flash). And if all this without you can not see on the site of what we would like hence the search engine can not, so draw your own conclusions – change the design.
