Let's start from the past: the Five of Wands indicates that in your past you have met a certain number of people who have not proved to be compatible with you. You may have had some heartbreaks, but that doesn't necessarily mean you can't find the love of your life online. The Five of Wands suggests that you are ready to let go of past disappointments and try something new.
The reversed Knight of Wands indicates that you are currently facing difficulties in finding love. It could be that you are afraid to open up to others or maybe you think you don't deserve love. This card suggests that you should overcome your prejudices and put all negative emotions aside in order to find someone who is truly compatible with you.
Finally, the Ten of Pentacles suggests that your search for love may finally lead to some positive results. The card suggests that you are starting to see some possible candidates to meet via an online dating site and while there may still be some moments of frustration, you will eventually arrive at some positive outcomes.
Bottom line, the cards suggest that your odds of finding the love of your life on an online dating site are good. Even if you have encountered some romantic disappointments in your past, you need to let go of those negative emotions and open yourself up to the opportunities the site offers. If you continue to be patient and positive, you will eventually achieve good results. So, the answer to your question is "yes".
