Among blog accessories that are not going to get you good reputation, I can't think of very many more obnoxious than the FaceBook "Like my blog, before you read it!" demand.
Currently popular with some WordPress blogs, this is yet another blog accessory that will eventually get the blog deleted, as a possible malware host.
Useful Blogger blog readers look for blogs with informative, interesting, and unique content. Hiding a blog behind a "Like my blog!" demand, to help you boost FaceBook popularity before the blog can be read, will not get you useful readers.
Similar to bogus page password protection, social networking popularity popups will impede access by malware scanning.
Robotic processes, such as search engine bots, cannot continue.
When a robotic malware scanning process encounters a FaceBook "Like my blog!" popup, it's going to simply add your blog to the queue to have it locked, as a potential malware host. You will later have to remove the popup code, and get the blog into the malware review queue - and suffer the inconvenience, and reputation loss.
Popup windows are not well regarded, in some security products. Popups have been long popular, with devious malware and spam vendors, to convince an unwary computer owner into "Agreeing" to have more malware installed in the host computer.
Even if the blog isn't locked as a possible malware / spam host, it may not be properly crawled. Both the AdSense ads classifier - and the Google Search crawler - may not index the blog. Both ad content - and search engine indexing - may be at risk, with popup windows covering the content.
The "Like my blog to read my blog!" popup is simply a way of buying Likes.
If you advertise your Blogger blog in FaceBook, simply to get people to read your blog and generate one more "Like" for your FaceBook page, so more people will read your blog, you are simply buying Likes. Eventually FaceBook will wise up, and stop encouraging this circular popularity boost technique.
Hopefully, Blogger Policy Enforcement can take action, before Blogger blogs gain one more bad reputation for scammery and spammery - and explicitly add this technique to the malware detection rules.
The readers that you do get won't read the blog content.
In the mean time, the readers that you will get will be similar to "GPT" technicians. These are the people who are not reading a blog, or the ads - because they are busy clicking to get to the next blog, and the next set of ads - because they, like the blog owner, want more money.
Even if you gain a "Like", you'll not be gaining an actual reader.
