New to Blogging? - the worst blogging mistakes

When I started this blog, blogging wasn't a huge social phenomenon. At least, not as huge as making Youtube videos. However, with the growing interest in beauty that Guru's channels have arisen, and most Gurus also having their own beauty blogs, beauty blogging has reached unexpected proportions.
Over the past months, I witnessed a whole new and growing community, especially here in Italy.
When you are a blogging veteran already, you can certainly distinguish bloggers who start blogs just to get freebies, and those that have something true to say and have potential, although they still have some things to learn.

Therefore, this post is aimed to new bloggers who do have some passion and potential, but are taking some steps wrong. I think it might be useful to have some guidance, because I am one of those bloggers who adhere to the "Blog with Integrity" concept. Here are a few tips I want to share, for you to fix mistakes that you don't even realize you're making.

1. Don't post random comments on random posts, just to leave your blog's address: that's annoying, and perceived as spamming;
2. Don't even post pertinent comments under posts, leaving your blog's address at the end of it: that's also perceived as spamming, and a subtle way of doing it. Not classy;
3. Don't EVER post comments like this one: "Hi, I'm a new follower/new blogger. I follow you, can you reciprocate?". That is just the most CLASSLESS thing ever. Hence the banner that I have on my left-hand sidebar, which I share with lots of other bloggers (it was created by the gorgeous Aru from Glamorous Makeup);
4. Don't send popular bloggers e-mails advertising your blog, and asking them to follow you, just because you want their subscribers. That's just as bad as the previous 3 points. You see, if you have a blog, your profile is active already, therefore I can click on your name beside the comment and just check your blog out, intentionally! So there is no point in spamming! And most bloggers do check out blogs who comment them (at least, I do);
5. Don't host giveaways with the only intention of gaining followers. I personally think it is a bad move to say "when I reach X subscribers, I will host a MAC giveaway". It is nice to host giveaways when you want to thank people for their support, and it is obvious that it is also nice to have some new followers thanks to a giveaway, but...why should you collect followers just for the sake of it? Isn't it more rewarding to see people take the time to comment your blog, appreciate your work and support you? Giveaways are nice, fun, and easy, but they should be handled the right way;
6. Be original in both style and content: I know it is hard to stay original with backgrounds and stuff, but you can always make your blog more personal with sidebars, headers, fonts etc. It's not nice to see a thousand replicas of your blog;
7. Blog with integrity: post honest reviews, don't blog for the freebies. They'll come your way nevertheless if you work with passion and dignity (we all enjoy perks, so I won't pretend like I don't).

I hope this was helpful. Bear in mind that I don't really want to be harsh on anyone, just give honest tips to people who deserve them; people who have a potential, but are just starting.

Of course, I'm open to discussion ahah...
So let me know what your "worst blogging mistakes" or "blogging pet-peevees" are :)
