Struggling Blogs

I got two new blogs that I made. One is for a wife's place where she can vent all thoughts and opinions on articles that are relevant to married life, relationships and family. I have this blog for more than four months now. I tried submitting it to a paid blogging site and has been rejected multiple times for many reasons.

The recent blog I made which is a month old is my gardening blog. I can understand why it hasn't been indexed by Google yet since it's very new still. However, I would love these two blogs of mine to be indexed by G so when it's time to submit them to paid blogging sites they will be accepted right away. Money is always scarce for me and for that reason, I make a way to bring in more through adding new blogs to submit.

These two new blogs I am talking about are somewhat struggling, aside from not being indexed in Google, they also have not ranked either. Perhaps, asking for link exchange helps? I might do that and visit those link exchange sites and see if it does help for I truly want my blogs to be accepted, let them be known to the blogosphere that they exist too.

I'll just give them time to grow for more months though. Anyway, I am in no hurry. I know it takes a while for a blog to develop, driving visitors into them isn't easy as well. You'll have to burn your time visiting from one site to another asking for blog authors to visit you back.
How about you guys? Do you find it difficult exposing your blog to your targeted readers? How long did it take you to stabilize your blog? How many blogs do you own?
